Ronto, Sean 2006 Journal Tributary of Cottonwood Creek, Adden Trout Wilderness, and Charlie Canyon, N Fork Oak Creek, clnyr Co., CA May 24 I hiked from the Cottonwood Canyon trailhead up Cottonwood Creek for a short distance before turning west and hiking upslope to a saddle at the top of the ridge. From here, I hiked west at a more-or-less constant elevation (a little uphill) up the canyon of the unnamed tributary of Cottonwood Creek where my data logger is. I saw a gopher snake (Pituophis catenifer) among lupine and shrubs in sparse pīnör vegetation (36.44137°N, 118.09500°W [WGS84; Gm acc.), 1926 m elev). I also saw many Uta, Aspidoscelis and ground squirrels. I continued west and descended to the creek about 150m before the waterfall where my data logger is, and hiked up to the waterfall through dense willow, cottonwood and oak. I arrived to find that my data logger was flipped upside down, though still attached to its pole, and its data port cap was on the ground beside it. I tried but failed to download data, and the LED wasn't blinking; so I took the logger with me. I searched the area of the waterfall and then climbed up the left side; this was extremely dangerous and I would never do it again. I walked upstream about 200m through the narrow rocky canyon, flipping rocks along the stream, [illegible] and I stopped at the point where the canyon opens up and widens. There was one area near the top on the N side where several springs emerged from a granite wall, forming a wet messy area with rocks laying

Routes, Dear 2006 Journal May 25 Pine Canyon and Sawmill Canyon, Inyo National Forest, Inyo Co., CA I drove up the road to Onion Valley and parked at Strays Meadow campground. I hiked up Pine Canyon, just south of the campground, where Chris Fitchell found Hybomantea last summer. I started at the level of the road and hiked about two-thirds of the way up the canyon. The creek was usually bordered by very dense willow and wild rose as well as pines and other trees. Many areas had horsetails and grasses and looked like the habitat at Shanna or Charlie Canyon. I flipped many rocks on the way up along and near the stream, but found nothing. The vegetation was too dense to easily access portions of the stream, so I didn't search those areas. The rock was white and seemed almost like travertine--I don't know what it was. About halfway up, the stream formed a series of messy cascades with caverns on the sides, which I searched unsuccessfully. I turned back at 1:30PM, having gotten a good way up the canyon (high point: 36.77247°N, 118.30369°W [WGS84, 10m acc.], 2122m elev.) in two hours of hiking. I hiked down to my car and drove north to the mouth of Sawmill Canyon. I crossed through dense cottonwood and willow trees across Sawmill Creek at the mouth of the canyon. I climbed over a talus slope on the south side of the canyon and reentered the vegetation below the rocky south wall of the canyon. After a brief search under rocks and logs along the stream, I found two juvenile H. platyphalus under granite rocks in leaf litter next to the stream (36.91242°N, 118.29037°W [WGS84, 14m acc.], 1512m elev.).

Pinto, Jean 2006 Journal May 25 Pine Canyon and Sawmill Canyon, dnyrs NF, clgyr G., CA (cnt.) ...cl collected both (SMR 95+96) since all the tissue from her juvenile was ground for allergene work. cl found another salamander in a mossy area next to the stream under a rock, but it fell into water below some tree roots and escaped. cl found a fourth juvenile in a mossy seep area at the base of the canyon wall; and took both dorsal and ventral swabs (for hybrid testing). (SmC1 - Sawmill Canyon 1). There were several other small seep areas, but none had rocks to turn. cl searched up the stream a bit more but found nothing; altogether, cl searched from 4-5PM. This canyon has the most shaded areas, mossy spots and leaf litter of any cl have seen yet, and appears to have a lot of suitable reparation habitat for these salamanders. cl walked back to my car and drove to Pine Creek to camp. The day was clear and hot, with a high of around 95F. May 27 Pine Creek, Shanna Canyon and Sparkle Canyon, dnyrs NF, clgyr G., CA cl woke up and hiked up the side canyon of Pine Creek where my data logger is (site PC(1)). The lower part of the canyon was filled with snow; up to about where my logger is. Lots of debris and sand indicated that the canyon had flooded, and the area around my logger had lots of dried mud and dead plants. The logger itself was still attached to the pole and apparently functioning, but the pole had bent in the middle at a 45° angle. cl searched the creek for about 50m above the data logger, flipping rocks near the stream, and found 3 adult H. platycephalus.

Ronto, Sean 2005 Journal June 5 Half Dome and Vernal Falls, Yosemite National Park, Mariposa Co., CA Last night, cl stopped at Camp Curry with Chris Martinez, Solano and David Buckley. We hiked through the tent cabin area to a small stream and then followed the stream up to the granite wall at the south end of the camp, where it became a waterfall. There were lots of mossy cracks and plenty of wet areas, some with significant flow. cl found a juvenile Hydrotaphalus crawling on the wet granite wall at 10PM. The air temp was 82.0°F and 69.6% RH. We continued searching and found a Pseudacris, as well as another H. platycephalus which I collected (SMR 97: 37.73538°N, 119.57471°W [WGS84, 14m ase.], 2282m elev.). There seemed to be a lot of very suitable habitat near the waterfall, but the rock elsewhere was dry. The next morning (June 5), we hiked out from the Happy caves trailhead up the John Muir trial, starting at 10AM, and arrived at the top of Half Dome at 2:36PM. It was a sunny and clear day; and fairly warm (probably in the 80s). On top of Half Dome, there was a small snowfield in the center, with a lot of seepage and exfoliated granite rock on the NW side. David and cl searched and found 14 juvenile, 1 subadult and 5 adult H. platycephalus between 3 and 4:30PM (37.74507°N, 119.53387°W [WGS84, 7m ase.], 2622m elev.). cl got dorsal and ventral swabs of the adult and subadult salamanders, but the juveniles were all too small to swab. We searched all of the available habitat on this side of...

Davis, Dean 2005 Journal June 13 Crooked Creek and Cottonwood Creek, Kings National Forest, Mono Cr., CA - I drove out to Bishop yesterday from Berkeley to meet Sean Schrihle. This morning we drove up into the White Mountains and stayed at the Crooked Creek station. We drove down the Crooked Creek road until it became too muddy, at which point we walked down along the creek. The area was grassy with sagebrush, with some aspen along the creek. We flipped rocks along the creek and Sean found a few cardinal beetles. We continued down the creek to an area with some willows, but there wasn't much leaf litter or many cover objects to turn (37.4981°N, 118.1124°W [WGS84, 7m acc.], 2798 meters). We searched along the creek from 12:30-2 PM, but there wasn't an area that looked like good salamander habitat. We attempted to drive down into Cottonwood Creek but the road was too rocky. We returned to the Cottonwood Creek road at 7:45 PM, parked and walked down the road until it met the creek. The water emerges from a spring just above the road, goes through a meadow and then flows through dense willow growth. Sean and I searched from 8:30-9:30 PM. There were some areas below the road where there was a thick, moist layer of leaf litter and some dead wood. At the end of the area (east end) that we searched, there were some good-looking mossy areas along the creek (37.53138°N, 118.16267°W [WGS84, 5m acc.], 2828 meters). We did not find any salamanders, but this area has a fairly large area of suitable-looking salamander habitat. The weather today was cool, mostly clear and windy.

Ronto, Sean 2006 Journal Chiatovich Creek, Emeraldia Cr., Nevada June 14 Sean and I drove from Grocked Creek down to Hwy 178 and into Nevada and north through Fish Lake Valley. We went up Chiatovich Creek Rd. and drove until the road ended at about 8000 ft. We started up the North Fork of Chiatovich Creek at 12 PM. Around 10,000 ft the stream was bordered by willows and had many branches with some areas with extensive leaf litter. We began searching at this point and worked our way upstream. The canyon became narrower and snowier, and we flipped rocks along the stream near the snow. We stopped in the wide area near the top of the canyon, just below the steep snowy slopes leading up to the crest (37.79529° N, 118.32421° W [WGS84], 9 m acc.), 3363 m elev.) at 4 PM. We hiked over the ridge to the south to enter the South Fork of Chiatovich Creek, arriving at some springs feeding into the creek near the top at about 5 PM (37.78350° N, 118.31048° W [WGS84], 5 m acc.), 3293 m elev.), above the treeline in a grassy area. We walked downhill along the stream, flipping rocks and wood. We passed into a pine forest (lumber pine, I think) where there were many logs to flip, but it was only wet within a foot or two of the stream. The area around 9000 ft looked particularly good, with many logs and rocks in wet stream areas, and could be suitable for salamanders. As we descended, the stream passed through grassy areas and became less suitable. We stopped at 6:30 PM (37.79452° N, 118.29086° W [WGS84], 9 m acc.), 2759 m elev.) and walked back to the car. The day was cool and cloudy. We drove back to Bishop, and it rained lightly along the way.

Ronto, Sean 2006 Journal June 16 Great Falls Basin, China Lake Naval Air Weapons Station, Inyo Co., CA Ted and I met Tom Campbell and a team of archeologists from China Lake and drove to the junction of the road to Mt. Maturango Peak and the road to Birchen Spring. A fuel truck met us there and we waited until a helicopter arrived. The archeologists wanted to look at several petroglyph sites and we wanted to put pitfall traps into several springs in Great Falls Basin below Argus Peak. We all got into the helicopter at 10AM (it fit 9 people) and flew south. Ted and two friends of Tom were dropped off somewhere in the general area of Deep Canyon Spring and then I flew north. The east slope of Argus Peak coming down into Great Falls Basin seemed to have superior spring habitat in nearly every canyon, and some springs appeared to have surface flow and larger trees (probably cottonwoods). A GIS contractor named Dave and I were dropped off in the canyon west of Willow Spring at 10:30AM. We hiked down off the small flat ridge where the helicopter landed into the stream area. There were several pools of water with Bufo punctatus larvae in them, some of which were extremely small and shallow and others of which were at least a foot deep. There were probably at least a hundred tadpoles between all the small pools. I found 2 small toads and collected one (SMR99 - use GPS from trap 3). We walked upstream to find good areas for traps. Most of the streambed was either dry sand or damp sand, with isolated pools of water. Thick, tall grass and clumps of willow bordered the stream. We had a hard time finding areas that were moist and shaded but out of reach of flooding.

Frinto, Dean 2006 Journal Great Falls Basin, China Lake NAWS, dnyrs Co., CA (cont) June 16 We put in the first trap in a clump of willows in moist soil (Trap 1: 35.85536°N, 117.39775°W [WGS 84; error not] UTM Zone 11:N 3967979 E464087, 977m elev.) Each pitfall trap consisted of a paint can filled with 0.5L of propylene glycol (antifreeze) and had a 18in. square tile lid supported by 3 small rocks around the can and weighed down with a big rock on top. We put Trap 2 in the center of a clump of willows just above a small pool of water in moist soil with leaf litter on the S side of the stream (35.85492°N, 117.39853°W [WGS84], 982m elev; N 396793G, E 464017). We put the third trap under a very large boulder in a cave-like area with a sandy floor and a damp area where the rock met the soil (35.85503°N, 117.39739°W [WGS84], 967m elev.). The area under the rock had damp soil with holes and dead roots where salamanders could live. We put traps 4 and 5 next to the stream in a small clump of willows just upstream of the largest pool along the stream (35.85428°N, 117.39653°W [WGS84], 960m elev.). The stream habitat appeared to get even better below us, but we had no time to look. The helicopter collected us after 12:30. We attempted to find another spring with surface flow and a suitable landing site in the area, but couldn't find one, so the helicopter dropped us off at Bircham Spring. Most of the spring was dry and the bushes were impenetrable, so we walked back to the fuel truck. Jedi's group came back without seeing any amphibians, and we drove back to Ridgecrest. The day was hot and sunny, in the 90s, with some breeze.

Fronto, Dean 2006 Journal Eagle Lake, Lassen National Forest, Lassen Co., CA June 18 Yesterday I drove from Redcrest up to Eagle Lake to join the MVT team doing survey work there. Along the way, I stopped at the H. platycephalus site at Lake George in the Mammoth Lakes basin to try to get limnetic swals samples. There was a lot of snow all around, but the salamander bog habitat was snow-free. I turned all the rocks in the immediate area and found only a single juvenile Hydromantes. It was too small for limetal surveys, but I took a ventral swals for chytrid testing - Lake George ! [LG(1)], I searched the area for about 20 min but saw nothing else. Today, Chad Martin, an undergrad working for the Lassen transect survey, and I went to the mouth of Pine Creek on the west side of Eagle Lake to look for frogs. We checked an array of pitfall traps there but found nothing. We then walked down to the wet area along the lake shore and found many B. boreas tadpoles and metamorphs, as well as 1 live and 3 dead Spea intermontana tadpoles and one Rana cascadae tadpole. We collected specimens of each (SMR 104-108). We also caught 2 adult Thamnophis elegans (SMR 102+103). The habitat was wet and marshy with tule reeds and grass. There were lots of birds including Blackbirds, terns and white pelicans. Next we headed up a dirt road to a section of Pine Creek west of Spalding. We searched for about 30 min: I chased a Sceloporus that escaped, and Chad caught a S. gracilis at 1:30PM. The habitat was ponderose pine forest with lots of downed wood and rocks. We drove back to camp, prepped specimens, and went road cruising at dusk but found nothing. The day was warm and sunny, and cool in the evening.

Pinto, Dean 2006 Journal Papoose Meadow, Eagle Lake Area, Lassen National Forest, Lassen Co., CA June 19 Chad Martin, Allison Schultz, and I drive to Papoose Meadow, just south of Eagle Lake. We parked at the SW end and surveyed from the edge of the meadow into open ponderosa pine forest to the west. We saw many Leucorrhinia frigida juveniles in the grassy areas, and I collected 2 (SMR110,111). I found a large adult B. horvathi under a log (SMR112). In the middle of a grassy area in the forest, I saw what looked like an Elysis among a pile of leaves, but I only got a good look at the tail; it may have been a Scalopus. I collected a juvenile S. gracilicornis that was foraging on a log. We surveyed this area from 9:15-10:50AM and then drove north along the west edge of the meadow to an abandoned cabin. We checked the wood and tire around the cabin but found nothing. Chad searched around the woodpiles in the meadow while Allison and I walked across the meadow. We made it about two-thirds of the way across; the meadow became wet, with water above the knee in places, and thick grass. We caught a L. frigida juvenile and a tadpole (SMR120,119) in a deep pool. In a shallower grassy wet area, we found a B. horvathi metamorph (SMR122) as well as a Theranophis elegans adult (SMR121). We saw 3 other T. elegans but let them go. We caught an adult J. vernalis in a drier grassy area near the wet part of the meadow. Near the woodpiles, Chad collected a T. elegans (SMR114) and 2 J. vernalis (SMR117,118) under logs as well as a L. frigida (SMR115). We stopped searching at [illegible] and headed back to camp. We intended to drive for hours, but ended up preparing specimens until after sunset. The day was fairly hot and partly cloudy.

Hosts: Sean 0605 Journal Breckenman lava flows and Merrill Creek, Eagle Lake area, Lassen National Forest, Lassen Co, CA June 20 Chad and I drove north on Al (Eagle Lake Rd.) to the Breckenman lava flows where the mammal survey team had trapped earlier. We drove down the dirt road to Breckenman lava flow until it became too muddy and then parked and began to search at 9:15. The area had ridges formed by lava rocks with sparse vegetation interspersed with sandy scrub/brush areas with juniper, a few pines and some shrubs. We saw many Xalopurus occidentalis on the lava rocks, and many D. gracilis on the rocks and on the sandy soil. The D. gracilis seemed to stay nearer to vegetation while the D. occidentalis were more on top of large rocks or in crevices. I caught two of each species and Chad caught 1 of each (CMM12-17) between 9:15 and 11:45. We did not see any other horps at this site (40.58621°N, 120.84012°W [WGS84, 10m acc.], 1555m elev.). We drove south and stopped at a small, rather stagnant muddy pond with sparse vegetation at the entrance to Christle Campground. (40.56727°N, 120.83918°W [WGS84, 10m acc.], 1566m elev.) CMM18+19 We quickly collected 2 R. dequilla juveniles and one T. elegans (CMM 20). We then drove south to Merrill Creek, drove ~100m W up a dirt road and began to survey at 12:20. I quickly found a D. gracilis along the creek (CMM21) and Chad caught another (CMM22). (40.54576°N, 120.80999°W [WGS84, 11m acc.], 1579m elev.). We searched up a branch of the creek that opened up into a large meadow, but found nothing and stopped looking at 13:15. We went back to camp and propped specimens. Jim McCluskie and Craig Morty arrived in the evening; Craig and I went night driving around the lake but saw only 1 BOR Colder.

Pants, Sean 2006 Journal June 21 Area east of Eagle Lake, Lassen Co, CA Craig Norris, Jim McGuire, Chad Martin and I drove to Golding and stopped to survey the area near Pine Creek where mammal trapping had been done (40.66074°N, 120.79124°W [WGS84, 6m acc.], 1576 m elev.) on the W side of Golding Road. The area had yellow pine, sagebrush and lava rock. We searched from 11:00-11:35 and caught S. occidentalis and S. gracilis (13 total, to get Jim's catalogue numbers). We drove around to the north end of the lake and stopped in an area with sandy soil, sagebrush and grass in full sun. We searched for about 20 min in the sandy and rocky areas but got only 1 female S. gracilis at 12:10 on sandy rocks (JAM6 - 40.58896°N, 120.78606°W [WGS84, 10m acc.], 1569 m elev.); we saw many more S. gracilis. We then turned south on Hwy 139 and stopped 1.6 mi S of the intersection with AI (JAM 7). We searched up the rocky slope covered with sagebrush and juniper from 12:55-13:35 and caught 2 S. occidentalis. Chad found a dead Masticophis tarasius with its head on a rock, but we didn't collect it. We stopped 13.1 mi S of the intersection with AI to collect a roadkilled C. constructus at 14:20 (JAM 8) and then drove east of Susanville on A27. We went up Word Lake Rd for 1.9 mi N and searched between (40.41970°N, 120.42339°W [WGS84, 6m acc.], 1300 m elev.) and (40.42434°N, 120.42543°W [WGS84, 6m acc.], 1285 m acc) between 15:45 and 17:30. The area was flat with sagebrush and very dry, with no trees. There was a ditch bordered by two rock walls. We caught several S. occidentalis on the rocks as well as 3 Crotaphytus viridescens. We then caught 4 Gambelia wislizenii including a gravid female. Chad saw 2 Aspidoscelis tigris but

Rosita, Dean 2006 Journal Virginia Lakes, Mono Co. and Convict Creek, John Muir Wilderness, Mono National Forest, Mono Co., CA July 1 Yesterday I drove from Bariboy up to Sonora Pass. I offloaded the data from my logger at the 9000 ft sign onto the shuttle at 3:50 PM. I searched in the area below the logger near the stream where there were some mussel cracks with seepage and saw 1 adult female (SP17), 1 subadult (SP18) and 4 juvenile I. platycephalus. I got dorsal and ventral swabs from SP17 & 18. I drove to Virginia Lakes and stopped at Sardine Falls on McKay Creek, on the E side of Sonora Pass on the way. I searched a seep area next to the falls and a little of the spray zone for ~30 min (1445-1815) but saw nothing. The habitat looked perfect, and Chris Fitchell found salamanders here last year. On the morning I hiked west from Virginia Lakes looking for seep zones. I made it as far as a small lake past Corney Lake (38.84-863°N, 119.28121°W [WGS84, 13 max], 3158 m elev.). But could see no suitable habitat, even using my binoculars. I left, drove to Convict Lake, and hiked up the Convict Creek trail to my data logger. The creek was extremely high and only ~10m of habitat was exposed. I searched it from 1400-1445 and found 7 juvenile salamanders, as well as the following ones that I swabbed (dorsal/ventral): Swab # Age/Sex Photo Swab # Age/Sex Photo CC17 subadult 1030018 CC20 subadult 1030024 CC18 subadult 1030019 CE21 adult ♀ 1030030 CC19 subadult 1030020 I also saw 2 subadults that escaped. I offloaded my data logger at 1516 and then pulled it out and took it with me. The day was sunny and warm, in the 80s. 38.30849°N, 119.62140°W [WGS84, 5m acc.] 2676m elev.

Ravito, Dean 2006 Journal July 3 Sixty Lake Basin, Kings Canyon National Park, Fresno Co., CA Yesterday, I met Dean Schenille at Onion Valley in the morning and we hiked up Kearnsburg Pass, down to the PCT, and over Glenn Pass. On the north side of Glenn Pass, we hiked down over lots of snow and then up "Shortcut Pass", between Glenn Pass and the 60 Lake Basin. About 200 m NW of the bottom of Glenn Pass on the ridge, Dean found a subadult H. platycephalus. He then found 5 juveniles, all under rocks along snowmelt streams on granite, with grass and heather among the rocks. I found another [illegible] subadult at 1550 and collected it (SMR [illegible]) (36.79549° N, 118.41489° W [WGS84, 5 m acc.], 3454 m ele.). We found the salamanders in the same area where Tate Funstall had seen them several years ago. We met Nancy Brodenburg and Tate in 60 Lake Basin and stayed at their campsite. We spent this morning waiting for Nancy and Tate's supply helicopter and moving their supplies to camp. In the afternoon, we went to the lakes east of Mt. Clarence King (lakes #10-14) to do frog surveys and swabbled ~40 tadpoles (saw many more), but found no R. muscosa adults or metamorphs. We then hiked up to the waterfall south east of Mt. Clarence King where Tate and I collected Hydrobatotes suks last year. We started searching along the bottom of the waterfall and then climbed up the left (west) side. About halfway up the waterfall, Dean found an adult salamander at about 1500 under granite rocks with seepage. Dean, Tate and Nancy proceeded to find 5 other salamanders in the area, but two of the subadults escaped before I could swab them. This is the same location where I got adults from last year, so I continued with my Sixty Lake (2) [SL(2)]

Ronto, Dean 2006 Journal July 4 Sixty Lake Basin, Kings Canyon National Park, Fresno Co., CA I hiked up the stream on the east slope of Mt. Cotter and started surveying the seep zone on the south side of this basin at 0930. I continued up the south slope, flipping rocks in the seep areas, but found nothing. I made it all the way to the base of Mt. Cotter at the top of the basin and then started down the north side. Most of the seep areas were dried up, but I found 3 juvenile I. platycephalus under small rocks in a fairly dry granite seep zone with a little grass and heather (36.84231°N, 118.43736°W [WGS84, 7m acc.], 3465 m elev.) at 1115. This is the same spot where I found salamanders last year. I walked down to the small waterfall above the lake. The habitat looked perfect for salamanders, but I found only 1 Iolivia, which I collected for Dean & . It started to rain (some freezing rain) and thunder at 1200, so I went back to camp. Nance, Jate and Dean returned and we sat in the tent and drank lots of whiskey. I went to sleep at 4PM, waking up at 2100 to set before going back to bed. Dean and Nance went to the seeps on the S side of Mt. Cotter, in the general area of my data logger. They swabbed 5 salamanders, including one found out on the snow, at (36.81178°N, 118.43306°W [WGS84, G mass.], 3376 meters). No photos of the salamanders were taken.

Povits, Sean 2006 Journal Lake George, Mammoth Lakes Basin, Mariposa Co., CA (cont.) July 6 ...Finally, I drove to Lake George in the Mammoth Lakes Basin to try to get more samples from the site I found there last year. I walked past the usual site to a larger seep area just to the south (37.59714°N, 119.01509°W [WGS84, 8m acc.], 2799m elev.) and started searching at 1810. The habitat looked perfect but I found nothing. At 1835 I walked over to the seep habitat where I've found salamanders before and searched until 1905. I found 3 juvenile H. platyphena, one under a rock and the other 2 in mossy rocks. Water has stopped falling from above and this area will be dry soon. I think it would be necessary to search at night to find adults here, although I did look once at night last year and didn't see any adults. Today was warm, in the upper 80s, and mostly clear. Half Moon Lake, Resolation Wilderness, Eldorado NF, El Dorado Co., CA July 7 This morning I drove north to Lake Tahoe and past Fallen Leaf Lake to the Resolution Wilderness trailhead at the west end of the lake. I hiked up the trail to Half Moon Lake and searched a big waterfall and seep zone along the west side of the lake (38.89439°N, 120.14374°W [WGS84, 10m acc.], 2523m elev.). The rocks was volcanic but with lots of cracks, and lots of good rock-on-rock seep areas. It looked great for salamanders, but I saw none from 1555-1710. I did collect 1 Eurycea for Dean & S. On the way back I saw a potentially good seep zone on the N side of Cracked Cog, to the south of me. It was warm in the morning, with rain at 1700 when it cooled off.

Rostis, Sean 2006 Journal Bullfrog Lakes, Golden Trout Wilderness, Sequoia NF, Tulare Co, CA July 18 I hiked south from Mineral King in Sequoia NP over Farewell Pass. I left my pack in a grove of forest pines and walked with a daypack up a seldom-used trail to Bullfrog Lakes. I walked to the east end of the lower lake and started searching for salamanders at 1520. There were only a few small seeps here and none looked good. I searched along the brook to the upper lake and then began searching the extensive seep habitat on the northeast side of the lake around 1600. I found Pletharia for Seem 1 at 1605 (36.39803°N, 118.55389°W [WGS84, 7m acc.], 3335 m elev.). Much of the granite slope above the lake on this side was covered by extensive seeps and streams, with almost no vegetation aside from a few grasses, scattered herbs and moss. I found and collected an adult female H. platycephalus (SMR 138) at 1640 (36.40046°N, 118.55233°W [WGS84, 7m acc.], 3405 m elev.). I continued searching and found 6 more salamanders under rocks, 5 of which were gravid (36.40078°N, 118.55228°W [WGS84, 7m acc.], 3417 m elev.) - I sampled all of these. I also saw 3 tiny juveniles. Many of the adults here were speckled with orange-cream. It rained lightly in the morning and early afternoon, then cleared and was rather cool.

Priorito, Dean 2005 Journal July 20 Pear Lake, Sequoia National Park, Tulare Co., CA I hiked from Wolverton trailhead up to Pear Lake. Dave Draber gave me a list of salamander sightings in the park, and several were on the Watchtower trail. The Watchtower itself as well as the area above it looked pretty good for salamanders, except that the area is now completely dry. I stopped at Heather Lake and searched a large seep zone from 1130-1230 (36.60008°N, 118.68683°W [WGS84], 16m acc.), 2845m elev.) on the south side of the lake. There was lots of water dripping down and plenty of good rocks, so the habitat seemed perfect but I found only 1 beetle for Dean S. I continued up to Pear Lake. It started to rain and thunder around 1330 and continued intermittently until about 2100. I camped at Pear Lake and decided to search the extensive seep and waterfall habitat at the south end at night. I went down to Ranger Rick's cabin to find Nance, Dean, Andrea and Cherie Briggs, who I thought might be staying there. Nance and Dean gave me a H. platycephalus they had found the night before near a waterfall at the S end of Pear Lake after 24 hrs of searching. I went back and searched much of the habitat at the S end of the lake from 2145-2330. There were at least 5 large waterfalls and a huge amount of great-looking seep habitat with lots of water flowing, but I found nothing. This area surely supports (or could support) a large population of salamanders, but they seem to be quite hard to find. The area I searched was around (36.59607°N, 118.66487°W [WGS84], 22m acc.), 2979m elev.).

Fresno, Dean 2006 Journal Sierra Bear Lakes Basin, John Muir Wilderness, Sierra NF, Fresno Co., CA July 26 Dean, Schivile and I hiked from the Pine Creek trailhead up to the Bear Lakes Basin over Mt. Pass. On the way, we saw hundreds of Bdfo tadpoles and several small toads (B. cayugus, I think) in moisten habitat along the trail above Honeycomb Lake. The weather was cloudy in the afternoon but it didn't rain. We camped in the Bear Lakes Basin just east of Grant Lake. We searched in the seep area at the outlet from Grant Lake towards Little Bear Lake from 2130-2230 but found no salamanders. This is where I found one last year. We did collect a lot of Nebria for Dean. I pulled my data logger out at 2210 and deployed it at 2250. I was somewhat surprised not to see any salamanders, since conditions in the seep looked good, but this seems to be a hard site to find them at. There was still a lot of snow all around the basin. Sierra Bear Lakes Basin, John Muir Wilderness, Sierra NF, Fresno Co., CA July 27 Dean and I walked down to the bottom of the seep habitat below Grant Lake, to the area where I found a single H. platycephalus last year. We flipped rocks from 0934-0951 but found nothing. We then followed the creek down from Little Bear Lake west and then walked south to a large area of seep habitat, ~300m N of the Seven Adels Lakes west of Noe Lake. We started searching at 1045 and stopped at 1130. The habitat looked great, with extensive seepage over bare exfoliating granite with a southern or western exposure. Dean found an adult female H. platycephalus under a rock.

Ronto, Jean 2006 Journal Aug. 2 Wapama Falls, Hatchetchy, Yosemite National Park, Juneau C., CA I drove from Berkeley to Mariposa and then to Bridalveil to get my data logger, which I offloaded and pulled at 1455. The 140 was closed by a rockslide after Bridalveil so I couldn't get to my logger at Hite Cave from there. I stopped at my logger site at the Bear Creek tributary, pullout between Bridalveil and Midpines but could find no sign of my data logger- something must have happened to it. I drove back through Mariposa and then on 49 to Bagby, where I stopped to offload and pull my logger at 1610. Finally, I drove to Hatchetchy, where I camped. After dinner I walked along the N side of the reservoir to Wapama Falls, arriving after dark. The flow was greatly diminished from when I was here in April 2005. I searched a small area on the E side of the falls where lots of water was flowing down the granite face, but found nothing from 2050-2105. I walked around to the W side of the falls and searched the spray zone which was quite wet and buffeted by spray, from 2127-2137 without success (37.76416°N, 119.76690°W [WGS84], 11m ase.), 1201m elev.). The habitat looked pretty good for salamanders, but there were few wet rock-on-rock areas, and not many cracks in the granite walls. I think the salamanders probably don't live here. I noticed that Jewelala Falls is now completely dry- it looked like a good site in April. The day was sunny and hot, and the night was clear.

Paso Robles, San Luis Obispo 2006 Journal Bridalveil Falls and Cathedral Lakes, Yosemite National Park, Mariposa and Tuolumne Cos., CA Aug. 3 I started the day by trying to drive to the South Fork of the Merced, but Hwy 140 was closed before the confluence due to the rockslide. I drove to Cascade Creek and hiked up to the falls closest to the road. The area around the falls looked good for salamanders, but was inaccessible due to a large pool at the base of the falls and because of the sheer granite walls. I next went to Bridalveil Falls. After ~30 min of searching, I found it, offloaded the data at 1315 and pulled it out (37.71708°N, 119.64800°W [WGS84], 14m acc., 1275m elev.). I walked up to the falls, which were blowing from side to side erratically, making it hard to search. I searched most of the spray zone from 1325-1350, but water was pouring down periodically into the spots where I have seen salamanders before under rocks; I suspect they could not be under the rocks or on the ledges in these conditions. The cracks across the cliff might still offer them protection. I found a single dead, battered and decomposing H. platycephalus at on the same ledge where I have found salamanders before and collected it (SMR145). Finally, I hiked into Cathedral Lakes near Tuolumne Meadows and camped there. I explored the seeps above the lake where I found a single H. platycephalus in August 2004 (SMR18). I started searching at 2045. There was extensive water flow over the granite in the seep areas and conditions looked very good. I found the first salamander at 2158 and proceeded to find 3 more. All were on the west side of the seep zone, in

Rivets, Sean 2006 Journal "Fourth of July Chutes", Ellis Peak area, Eldorado National Forest, Placer Co. and Conness Lakes, Inyo National Forest, Mono Co., CA Aug.12 Yesterday, I hiked out from Smith Lake and drove to the Echo Lakes trailhead. I hiked to the southeast end of Lake Aloha along the PCT. The west side of the lake looked like it had some seep habitat below large patches of snow, but I didn't have time to hike all the way there. I hiked out since I couldn't see any nearby habitat to search, and camped at the Cascade Falls trailhead. This morning I met Will Richardson and Chris Seiger, grad students at the University of Nevada, Reno. Will had discovered a new population of H. platycephalus at a place called "Fourth of July Chutes" near Ellis Peak in mid-July. We drove up Barker Pass Rd. and parked in a turnout at a trailhead near the top. We then walked up the trail, which goes from the road to Ellis Peak, until we reached a switchback near the top. We continued south off the trail from here, putting us on the talus slope just below the top of the ridge on the east side. We walked ~100m to the base of the cliff below the ridge, where Will saw the first salamanders last time (39.06666°N, 120.22490°W [WGS84, 9m acc.], 2473m elev.). This spot had no snow, so we walked S and turned rocks around a small patch of snow but found nothing. We continued south to a large patch of melting snow beneath larger cliffs. We turned rocks on the talus slope next to the snow and found 2 juvenile and 2 adult H. platycephalus. All were under stones or moist soil from the melting snow, and 1 adult was under some of the abundant Griera primrose on the slope. I collected both adults (5MR146+147: 39.06560°N, 120.22768°W [WGS84, 5m acc.], 2484m elev.).

Kosito, Dear 2006 Journal Aug. 15 Lyell Canyon, Yosemite National Park, Tuolumne Co., CA Yesterday, Dean Schivile and I hiked from Tuolumne Meadows to near the top of Lyell Canyon. We camped in the meadows area beneath the upper bowl of the canyon, where Emily Rudige, Jim Patton, Les Chow and Peggy Gransta and Carol Patton were working. Dean and I searched some seep habitat just above camp to the east at night for ~30 min but found nothing. Today, we walked to the head of the canyon and searched an extensive seep area that stretched from near the canyon floor to almost the top of the ridge, on the east side of the canyon (37.75174°N, 119.25568°W [WGS84, 8m acc.], 3452m elev.). The seeps looked like spectacular salamander habitat, with lots of wet areas and grass, moss, Minulus and other vegetation. We searched from 1000-1115 but found no Salamanders. We then searched another set of seeps at the very end of the canyon; these had almost no vegetation and looked like excellent habitat as well (37.74903°N, 119.26000°W [WGS84, 7m acc.], 3405m elev.). We searched from 1240- 1320 but found no salamanders. On both areas, but especially in those seeps, some areas were fragni; made me wonder if the cold nights had caused the salamanders to retreat into cracks. We returned to the first seep (E side at top of canyon) with Emily and one of the botanists' friends who hiked in yesterday and searched from 2045- 2200 without success. Emily and the other girl stayed in the bottom part of the seeps while Dean and I climbed nearly to the top. The day was mild and sunny, and the night was clear with lows below 0°C.

Rivito, Dean 2006 Journal Ridge above El Rincon, Depto. San Marcos, Guatemala Aug. 26 After breakfast, the Wakes and Carlos went to Buena Vista (W of San Marcos) while Gabriela, Ted, Antonio and I drove to the village of El Rincon, just W of San Marcos on RN1. We turned off on a road that led up to the low point on the ridge (the "saddle") where many B. rostrata were collected in the 1970s. We parked where the road became impassible and hiked up to the saddle. We started searching at the top at 1030, but the habitat no longer looked good for B. rostrata. The formerly open areas had become overgrown with bushes and there was almost nothing to turn. We walked south and came to an area with some bromeliads. The first one we opened had a B. moris in it (14.9574°N, 91.85475°W [WGS84, 10m acc.], 2836m elar). Antonio found 2 more in a mass of fern rhizomes (like a rotten log) nearby. We continued south along a path through secondary forest and found 4 B. moris under rocks and 1 Theopsis morelata (14.95547°N, 91.84607°W [WGS84, 19m acc.], 2789m elar). Further down, we found 1 B. moris and 2 small B. lincolni under rocks along the path (14.95289°N, 91.84604°W [WGS84, 10m acc.], 2779m elar). The banks along the path looked good for Pseudocryaea but we didn't find any. We finally arrived in a planted cypress area with many bromeliads. I found 1 B. lincolni under the bark of a fence post (14.95094°N, 91.84686°W [WGS84, 15m acc.], 2766m elar). We pulled down bromeliads out of a cypress and found a tiny Baardstrita bromeliacea that was missing its tail. We then got ~10 more bromeliads from a large hardwood tree and found 4 more D. bromeliacea. I got 2 more bromeliads from a

Aug. 27 ... to walk around the lake, flipping and opening logs and flipping the few rocks we saw. The forest was in great condition and there were many big trees with some bromeliads (which we didn't open) and a lot of bamboo. Conditions seemed perfect, but we found nothing from 1130-1300. Antonio's finally found an adult Pseudoeurycea [illegible] under the trunk of a big log on the far side of the lake (14.78755°N, 91.65855°W [WGS84, 19m acc.], 2722m elev.). We searched until about 1500, with a 40 min lunch break but found nothing more. We searched in many excellent logs and CL was surprised not to see more salamanders. We walked back to the car and drove through Izuetaltenango and up to the radio towers on Volcan Siote Orejos. We searched in the open areas and cypress plantation/secondary forest at the top for ~40 min in a cold rain but found nothing (14.79280°N, 91.58773°W [WGS84, 6m acc.], 3104m elev.). There were some stumps to look in and the habitat looked OK. We drove down to ~2500m and searched for ~20 min but found nothing, and the habitat looked good. We drove to Xela, had dinner, and returned to San Marcos. Dave, Marshall and Ted had found 1 B. morio at Las Tules, but said the forest was gone. They found a P. dieg under a clump of mud in forest, 1 B. morio in a stump under trunk and a B. rzedowskii in a roadbank at Km 232.6 on the road from San Juan Ostuncalco to Palestina de los Altos.

Pinto, Dean 2006 Journal Aug. 28 Gordo Obtagel and Smith transect area, Depto. San Marcos, Guatemala. We spent the morning taking photos of salamanders in Buena Vista. The women there found one small B. maric for us. In the afternoon, we drove out of San Marcos, turned off RN1 at Pajapan, drove south through Jamil and then uphill towards the radar towers on Cerro Obtagel. We drove to the end of the road just below the towers and continued on foot. The area was largely corn fields but there were some open areas with rocks and brush that looked good for B. marictrata. We started searching at 1520 and Antonio immediately found a B. lineolus under a rock (14.70916°N, 91.81213°W [WGS84, 10m acc.], 3031m elev.). I continued uphill and found 1 B. lineolus under a dead agave in an open area and another slightly higher up in a stump in the forest. There was a lot of secondary forest further up the hill which looked good, but I found nothing more. I hiked all the way to the antennas on top of the hill, where there is a house. There was another open area that looked good for B. marictrata (3240m elev.) but I had little time to search there. I returned to find that the others had found 1 more B. lineolus and 2 Geophis godmani. We stopped searching at 1700 and returned to San Marcos for dinner. After dinner, we drove to the south transect by turning off at Pajapan from RN1, giving a short distance to a T-junction, and going right and passing the school. We searched the roadbank here from 2005-2125 and found 1 B. maric, 2 B. lineolus, and 4 B. franklini of franklini x lineolus hybrids (14.73616°N, 91.84349°W [WGS84, 9m acc.], 2475m elev.). All but the B. maric were in cracks in the only rocky area. We saw 2 more B. franklini and got a tail from one that was in a crack.

Royster, Dean 2006 Journal San Marcos to Tapachula, Depts. San Marcos, Guatemala and Chiapas, Mexico Aug. 29 We left San Marcos and drove to Tapachula, Mexico, where we spent the night. Between San Marcos and Malacatan, we stopped in Alden Colina II and searched in a banana grove next to a house from 1300-1320. We found 6 B. occidentalis under banana leaves (CRVA1035-1041: 14.99770°N, 91.95895°W [WGS84], 6m acc.), 758m elev). We also saw many tiny Craugastor here. We drove on to Tapachula and were hoping to look for B. thelwanus in roads in the rain, but it only rained from about 1600-1730 and the roads dried out. We drove up the road to Nueva Alemania and found a Bufus gansing on the road ~1.7km from the turnoff to Carrillo Puerto (14.9775°N, 92.2472°W [WGS84], 6m acc.), 342m elev). We swaddled it and released it later. We then took the road to Carrillo Puerto and found a Brachycephalus leuconotus 2.3km from the intersection with the road to Nueva Alemania (14.96002°N, 92.21344°W [WGS84], 8m acc.), 275m elev). We then found a Bufus walkiaps 3.7km up from the intersection with the main road. We drove further up the road but found nothing more; most parts were too dry for salamanders. Metajinta area, Chiapas, Mexico Aug. 30 We spent much of the day getting Mexican car insurance and getting the car through customs. We then drove to Metajinta, which took a long time because the road was badly damaged in last year's hurricane. We then drove back up to the pass on July 200 and

We stopped at a dirt road heading S, km from Hwy 200, and searched from 1800-18450.cl found a [illegible] in a bromeliad (15.36917°N, 92.33580°W [WGS84, 1m acc.], 2041m elev.). We then drove up the road and were dropped off at different points to search the road bank. cl search an area with high mossy rock walls, 20.5km by road from the highway.cl found a [illegible] and an adult B. franklini nigriflavescens on the rock wall between 2000 and 2100 (15.41922°N, 92.33464°W [WGS84, 12m acc.], 2538m elev.). Ted searched further up the road and J. debiola a few km further down; both found nothing. We picked up Antonio, who had found 2 Electryxyla along a stream 14.1km by road from the highway (15.38387°N, 92.38753°W [WGS84, 15m acc.], 2259 m elev.). Finally, we searched an area 3.1km from the highway for ~ 15 min and found another [illegible] (15.34473°N, 92.29615°W [WGS84, 9m acc.], 2063m). We spent the night in Motozintla. Cerro Motal, Motozintla area, Chiapas, Mexico Aug. 31 This morning, we took the road from Hwy 200 to El Porvenir and drove to the microwave towers at the top of Cerro Motal. Mariela immediately found a B.f. nigriflavescens under a piece of wood at 1210 (15.42621°N, 92.3496°W [WGS84, 8m acc.], 3016m elev.). cl found another one under a rock a few minutes later. cl searched in excellent- looking pine forest with lots of rotting logs and moss

We should have found Pseudourysces here but we didn't, even though the habitat seemed good. We drove km down from the top and searched along an abandoned road in secondary pine forest with some hardwood trees and many bromeliads from about 1400 to 1500. I found a Cerophidion godmani under a rock (15.42799°N, 92.33536°W [WGS84, 8m acc.], 287m elev.). The others got 3 B. f. migriflavescens and 1 Mesaspis modelti. We drove back to Motaguitla in a very heavy rain and had to wait ~1.5 hrs for a landslide to be cleared. We drove from Motaguitla south towards the town of Niquinil, but did not get far enough to find a good spot to work before dark. This area would be a good place to work in the future. Sept. 1 Cerrito Izantehuitz, San Cristobal de las Casas, Chiapas, Mexico We left Motaguitla and drove to San Cristobal de las Casas. On the way, we stopped about 4km S of La Fronterita to look for Bolitoglossa atrosti (16.08334°N, 92.04447°W [WGS84, 7m acc.], 1536m elev.). We searched from 1530-1600 under limestone rocks and in a few bromeliads in dry forest. The area was fairly moist and conditions seemed good, but we found nothing. We continued on to San Cristobal and drove to the top of Cerrito Izantehuitz, parking at the microwave towers. We searched on the roadbank with lights from 2000 until about 2100 in a light rain. We found 11 B. leopoldi; 1 juvenile and
Page 167
Havito, Jean 2005 Journal Sept. 1 Cerro Jaguachin, San Cristobal, Chiapas, Mexico (cont.) ... 1 subadult B. rostrata, 1 Bufo limacoides and 1 M. marabli. Conditions seemed good and I was surprised not to see more B. rostrata; they were apparently much more common than B. hartwegi in the past. We spent the night in San Cristobal. Sept. 2 Huitopee and San Juan Chamula, Chiapas, Mexico We traded chytrid swabs for our salamanders from yesterday, tropical frogs and went to the market in the morning. In the afternoon, Antonio and his partner Nora joined us and we drove to the Reserva Ecológica Huitopee, run by Pemex. The oak forest (Quercus rugosa and Q. crassifolia) was in good condition with lots of logs and some rocks to turn, and lots of moss. We searched from 1506-1600 and I found an adult B. hartwegi inside a stump. (16.75393°N, 92.68167°W [WGS84, 11m acc.], 2326m elev.). We then drove past San Juan Chamula towards Pantelho for 8.5 km on the main road and then turned right onto a dirt road and drove 0.2 km. We searched in the mud of the road bank and found 1 B. hartwegi and 1 B. lineatus in 30 min of searching (1700-1730) (16.84268°N, 92.69220°W [WGS84, 9m acc.], 2179 m elev.). We drove 1.0 km further and searched from 1740- 1825, and found 3 B. hartwegi, 1 B. lineatus and 1 Graugaster glauens (16.83866°N, 92.68642°W [WGS84, 5m acc.], 2196 m elev.). We then drove back past San Cristobal and towards Justita Gutierrez on the free highway and took the road

Ravito, Dear 2006 Journal Cerro de los Monos, near San Lorenzo, Finca de las Minas, Depto. Zacapa, Guatemala Sept. 6 Today we worked on Cerro de los Monos in the Finca de las Minas. We drove from the main road, took the turnoff to Ojo de Agua and drove on a dirt road through a locked gate with a guard for the marble mine at San Lorenzo. We went up a star but easily, possible (in our 4x4 truck) 19.7 Km from the highway to the marble mine and small village of San Lorenzo. We then turned onto a fairly good but seldom-used road leading N from San Lorenzo to Cerro de los Monos. From the Montania Valley, the vegetation changes from dry forest to pine oak forest to a forest with some small Bromeliads just below San Lorenzo. Above the level of the mine, the forest begins to have more bromeliads and gradually changes to excellent-looking cloud forest with large hardwood trees and many Bromeliads. We drove up to 2200m and stopped where a tree with bromeliads had fallen across the road. Carlos opened one bromeliad and found a subadult male Bolitoglossa with webbed feet, a red-brown color and spots on top of its tail at 133o (CRVA1042: 15.11328N, 89.67802W [WGS84, 9m acc], 2200m elev). Ted said it was the same as the Bolitoglossa sp., now "Finca Planada" collected here (a few) and at nearby Finca Planada (many). We walked up the road searching mainly in bromeliads and found a tiny juvenile of the same species in a large bromeliad growing at the top of the bank, only a little off the ground. The habitat here was more disturbed so we walked back to the car and drove ~10m down the road. I found a Cryptotriton sp. adult in a bromeliad in a pine tree (CRVA1044: 15.11223N, 89.67793W [WGS84, 9m acc], 2200m elev). Ted found a Xelopus tonacanonis here. We opened many bromeliads here but found nothing more. We drove down the road towards San Lorenzo,
Page 173
Ravito, Sean 2005 Journal Sept. 6 Corra de los Moros, Cerro de los Minos, Depto. Zacapa, Guatemala (cont.) ...opening bromeliads and searching in trunks and stumps until 1830 but we didn't find anything more. The habitat in this area was very good as well, and we could hear howler monkeys on the hill above us. We drove back down to the highway and the pine forest below the marble quarry looked like good habitat for mostly terrestrial salamanders (like B. melanura) but we had no time to search there. This area could use a lot more work in the future. The weather today was cloudy and warm. Sept. 7 San Jose Union, Depto. Zacapa, Guatemala We went to look for Cryptotriton mayesi, known only from the holotype. We drove from Rio Hondo and then to Escuintla, and then south on R0-5 for San Jose Union. We went SSE by road from San Jose Union and stopped 6.5 Km from town at an area of Cafetales. On the way from town, we passed through primary cloud forest with huge trees. I started searching in bromeliads from cypress trees at approximately 1200 but found nothing. Carlos and Ted moved on to riped bananas in the cafetal. Carlos quickly found an adult male salamander with brown speckling, swollen feet with somewhat triangular toes and black/brown speckled or mottled ventral coloration (14.93 768°N, 89.27569°W [WGS84], 9m acc., J, 1409m ele.) in a banana plant (CRVA1049). It appears to be either a Honduran species we aren't familiar with or a new species. Ted also found 3 B. infuscatus, and Carlos found a Amphisbaena taeniata. I found a nest of angry wasps. We searched here until 1420 and then drove 0.6 km down

Francis, Dean 2006 Journal Sept. 7 Near La Union, Depto. Zacapa, Guatemala (cont.) ... the road away from La Union to another cafetal with more bananas. In 30min of searching (1515-1545) d found 5 B. Rufescens and Carlos found 3 more, all in bananas (14.93264N, 89.27491W [WGS 84, 7m acc.], 1383m elev.). We drove back to La Union through the cloud forest, opening all bromeliads within reach along the road. The trees here are huge, and most of the forest appears to be intact primary cloud forest. Near La Union in tine forest, we found a female mouse opossum with 2 young in a bromeliad (14.95696N, 89.28109W [WGS 84, 11m acc.], 1347m elev.). We searched bananas in 1 more cafetal opposite Finca Santa Fe, 1.6km by road from La Union. Jed found a B. rufescens in ~20min of searching (14.95991N, 89.28574W [WGS 84 5m acc.], 112m elev.) at 1835. We drove back to our hotel, and Carlos collected a POR Bufo marinus 2.4km by road from Rio Montagua on the way from La Union to the highway. The weather today was hot and sunny with more clouds in the afternoon. Sept. 9 Coro San Gil, Matanzas del Mico, Depto. Chiquimula, Guatemala Yesterday, we drove from Rio Hondo to Santo Tomas, stopping at Antigua. We stayed at the Ocean Bay Hotel and tried to go up the road to the towers on Coro San Gil at night, but found out that the road is destroyed beyond the first kilometer due to storms this year. Carlos found some frogs (Rana palaveri, Leptodactylus labialis) on the hotel grounds at night, along with a Leptodyra. We spent all

Honto; Sean 2006 Journal Sept. 9 Corro San Gil, Montanas del Mico, Dept. Izabal, Guatemala (cat.) ... morning trying to get permission from FUNDAIO (Guatemalan NGO) to work on the reserve on Cerro San Gil, finally getting it in the afternoon. We drove up towards the GUATEL towers, parked at the guard station and started walking at about 1845. We walked up the road for ~1 Km, then Ted turned back to search on leaves at night, cl walked ~ 1km more and then turned back. At this point we found several Rana berlanderi (collected) and Agalychnis tadpoles in a puddle (15.68777°N, 88.66544°W [WGS84, 12m acc], 503 m ele.) at 1945. cl walked back, and collected 1 Craugastor along the way (15.68974°N, 88.66219°W [WGS84, 17m acc] at 2027. cl also saw a spider monkey. The forest was mostly secondary growth with some big trees, and lots of Heliconia and large-leaved aroid plants that looked good for salamanders. Carlos and Hugo walked on for about 30 min more and found 4 Bolitoglossa mexicana out on leaves, starting at 2000. They found a large (~1.2m) Bothrops asper male on the trail and killed it to collect it, since they had no snake [illegible] bag. They also caught a Liron and an clmantrides. Ted returned with another clmantidea sercora, a Craugastor and a Simlicola barlimi. cl stopped searching at about 9:15PM and the others stopped shortly after (2130 & 2145). clt started to rain heavily as we left, and Carlos got another Bufo vallecipi on the way back to the main road.

Photo, Year 2005 Journal El Cariche, Npio. Fajio, Depto. Cundinamarca, Colombia Sept. 28 I arrived in Bogota, Colombia on the night of Sept. 25. The next morning, Juan Paeira and I drove north to a small private nature reserve, El Cariche, just west of Fabio. Juan is working on his hummingbird project there. We set up his nets in the afternoon in a dwarf forest with lots of orchid shrubs and small trees, many ferns, lots of bromeliads, more Espeletia and a carpet of moss. I opened a few bromeliads and searched briefly but found nothing. After dinner, we walked to the Rio Chico, which begins at the reserve entrance and has a much taller forest with cedar trees, big ferns, and many bromeliads. The forest only covers the bottom and sides of the canyon and is bordered by eucalyptus. We searched from 2000-2300 along the creek but found nothing. There were two small waterfalls along the creek with excellent looking moss-covered walls that seemed perfect for salamanders. The next morning, I helped Juan with mist netting and we caught several hummingbirds. I searched for about 2 hours in bromeliads, but most were quite full of water and I found nothing. It seems very dry here and the carpet of moss on the ground was only barely moist. At 1500, I found a Phrynosaurus under a shrub and collected it for Juan's friend Rosario who studies this group (SMR 163: 4.93007N, 74.91208W [WGS84, 29macc], 2875m elev). I searched in bromeliads a bit more, and after dinner we returned to the mossy cascades along the creek and searched for ~45 min but found nothing. The day was sunny and fairly warm. This morning, I searched along the creek in logs, bromeliads and under rocks for ~45 min but found nothing. We must rested until noon and then drove back to Bogota.

Bogota, Dean 2006 Journal Parque Natural Chicaque, San Antonio de Tequendama, Apts. Cundinamarca, Colombia Oct. 3 Yesterday morning Juan and I arrived in Chicaque, a private reserve outside Bogota. We stayed in the upper camping area. The cloud forest here is in good condition, with lots of huge tree ferns, much bamboo, and fairly large trees including some Podocarpus. There are a few birdlife but not many, and most are out of reach. We spent the day setting up mist nets for hummingbirds. Before dinner, we walked up to the mirador and I found a small Bolitoglossa (adspersa?) under a rock in a grassy area on the edge of the cloud forest, along with 3 lizards (Phyllodactylidae) at 1800. I collected the salamander (SMR164: 4.60747°N, 74.30658°W [WGS84], 8m acc.), 253m elev.). We searched from 2000-2100 with lights in the forest and on banks on the edge of the path, but found only a single Eleutherodactylus. The next day, I spent most of my time at the nets with Juan. I returned to the mirador at 14:30 and found 2 more Bolitoglossa under a single rock in a small cleared area next to the path surrounded by ferns (SMR165+167: 4.60674°N, 74.30672°W [WGS84, 9m acc.), 2584m elev.). I quickly found a 4th salamander in the same spot as yesterday; it had been extremely dry but it rained a bit this afternoon, very lightly. Two of the salamanders are light brown in color, one is darker with light bands down its body and a light tail, and one is dark brown with lighter spots, especially on the tail. I flipped more rocks in the forest but found nothing. At night, I searched the same area as last night, along the trail below the camp towards the refugio, from about 19:45-20:30 but found nothing. The evening was clear and fairly cold.

Rivito, Sean 2007 Journal Feb. 14-15 Hite Cove, S Fork Merced River and Hell Hollow, Mariposa Co., CA Ricardo Pereira and I drove out to Mariposa Co. to check his pitfall traps for Ensatina and to get more buccal swab samples for my project. We drove to the locked gate on the road to Hite Cove from Jerseydale, arriving at 7PM, and hiked down to the salamander locality. I got my data logger, which had clearly been moved around then replaced by someone, and it wasn't working anymore. The weather was cool and fairly humid, and the ground was quite moist since it rained a few days ago, so conditions seemed ideal. We searched from 20:[illegible]50-[illegible]22:20 and Ricardo found an adult female Hydromantes brunus under a rock on the east side of the path. I got buccal and ventral swabs from it (HC4), I found only 1 Ensatina e. xanthoptica out foraging, which I didn't collect. Surprised not to see more salamanders out. We hiked back up to the gate and camped. The next day, we checked Ricardo's traps at Shingle Hill, Marble Latch, Wagner Ridge and Kingsley and got a fair number of Ensatina, especially at Wagner Ridge. We took the traps from Kingsley and moved them to a higher elevation site to the east near Anderson Flat. We spent the night in Shingle Hill and drove back to Hell Hollow after dinner to look for Hydromantes. We started searching at 20:05 at the locality in the first draw up from Lake McClure near Bagby and I found an adult H. brunus almost immediately. Again, conditions seemed very good for salamanders. We found a total of 4 H. brunus, all of which I swabbed:

Rovits, Sean 2007 Journal Ferguson Slide, near junction of South and Middle Fork of the Merced River, Mariposa Co., CA March 22 Yesterday, Ted Papenfuse and cl drove out to the rock slide site on Hwy 140 that we are surveying for Catrans. We searched this same site last week but found only a few Batrachoseps diabolicus. Last night, we searched the roadbank and nearby forest on the E side of the slide on the S side of the Merced; cl found 184 Ensatinia e. xanthoptica (collected #2- SMR 177-188) and 2 Taricha t. sierrae along the roadbank in mossy areas (37.65513°N, 119.89921°W [WGS84; 13m acc.], 435m ele.). We drove east 1 mile past the junction with the S Fork Merced and stopped for ~10 min to search a roadcut with some seeps. cl found a juvenile Ensatinia xanthoptica (SMR 193). We then drove back to the confluence of the South and Middle Forks and searched a mossy talus slope of Madrone and oak on the W side of the S Fork. The habitat looks ideal for H. burnsi, but we found only 3 Ensatinia e. xanthoptica (SMR 189-191) and 1 B. diabolicus (SMR 192) in ~15 to 20 min of searching. The next day (3/22) we returned to the Ferguson Slide and spent most of the day searching under rocks on the E side of the slide. We found 2 B. diabolicus (SMR 202-203) and cl got an adult female H. burnsi under a rock in a nice area of mossy talus in the woods (SMR 206) (37.65355°N, 119.89977W [WGS84; 10m acc], 502m ele.). This area is in a more open part of the woods but is still shaded and looks like great habitat. This is the first new population of H. burnsi that cl have ever found. In total, we searched this area from 11:30 - 14:00. and I Ensatinia, as well as some Taricha and a Orestias diogenus and a Heterophry punctatus and Ted found a B. diabolicus (SMR 194)

Hosts, Dean 2007 Journal April 30 Biosphere del Quetzal, Purulha; Depto. Bajo Verapaz; Guatemala I flew to Guatemala City overnight with Jed Paperfuss. We met Carlos Nasquez and his friend, Justino, who is interested in working with salamanders. We drove to the Biosphere del Quetzal near Purulha, where we had gotten permission to collect. We started searching along the shorter loop trail at 18:45 as it became dark. We walked the short loop with lights until 21:00. Carlos got a Electryhyla; and Jed got a Graugaster and a Plethodyle. I found a Thorops, a Graugaster sp., a different Graugaster sp. and saw a Electryhyla in a high bromeliad that escaped. I also found an adult male Bolitoglossa lehmanni foraging out on a Heliconia leaf. Conditions were rather dry, although it had rained the day before, and the temperature was mild. I think conditions are good for bromeliads but perhaps not good for looking under cover objects. May 1 Finca Sachet and Biosphere del Quetzal, Purulha; Depto. Bajo Verapaz; Guatemala We got a fairly late start today, since I barely slept the night before. We drove to Purulha and then 5 out of town and stopped to talk to Don Gregorio Cristo Xicel, who owns Finca Sachet, where Justino has worked before (tel: 59642195; 54870475). He owns 3 caballerias of forest that he wants to set up as a private nature reserve. We worked in good secondary forest on his land from 10:30 - 12:30. We mostly opened bromeliads (50-80 total) but I also searched in logs and under bark.

Rarity: Star 2007 Journal May 3 Finca Placida de Margoth, Depto Jucapa, Guatemala We met Julio Nargas in the town of Las Delicias after breakfast and drove through the town of Espinillo, through Finca El Cedral and arrived at his finca, which is called Placida or Margoth. He remembered Eric Koford, who collected mammals and salamanders here in the 1970s. He sent a man who lives in the village of Moran, Rodrigo Morales Aparicio, with us to the spot where he said Koford collected salamanders. The area around the finca is mostly second growth forest or scrub, but Rodrigo cut a path uphill to an area with bigger trees, which appeared to be primary forest that had been selectively logged (perhaps). There were many broadleaf trees with a lot of Bromeliads and epiphytes and a lot of big tree ferns. We started cutting down bromeliads at 12:10 and worked our way uphill. I found a Cryptotriton auramineus in a bromeliad after a short time in a nice area of forest. It looked like the one we found on Cerro de los Monos (it has a yellow ventor) unlike the grey ventor of C. aerapagis. It was also extremely active and actually jumped when disturbed - I have never seen a salamander do this before. We continued uphill through some less good secondary forest, and then got to the start of what Rodrigo said into a huge stretch of primary forest uphill. Carlos found a big C. siobrainensis in a bromeliad here (CRVA 117). We continued uphill and got to an area with huge trees and many bromeliads. I found a small Bolitoglossa larvichi or galapensis (CRVA 118) in a bromeliad. We continued
Page 235
Pinto, Jean 2007 Journal May 3 Finca Planada de Marzoth, Sierra de las Minas, Depto. Zacapa, Guatemala (cont)... to work in this area but found nothing more. I'm sure that if we had more time to work here, we would have found more salamanders. It started to rain at 17:40 and it became hard to work, so we stopped for the day and started back, getting soaked in the process. It stopped raining by the time we got almost back to the house. We cut down three very big bromeliads from a pine tree on the edge of the forest and got a big B. helminthi - a nice way to end the day. We returned to the house, where Don Julio was waiting for us with coffee and dinner ready - he really went out of his way to host us. He told us stories about his life and plans for the finca - he wants to build some cabins and start an extension program. He says that he has made a big effort to conserve the forest, and it appears to be true. May 4 We woke up early this morning and went out with Rodrigo after breakfast along an old road that goes down from the house. After crossing 3 creeks, we walked uphill into some primary forest. We started opening bromeliads at 9:00 and found 2 Bolitoglossa in bromeliads; one of which lost its tail and later died. I think that the larger, while one is Bolitoglossa zacapensis, the new species we are describing from here. Just up the road, we found 2 more Bolitoglossa in bromeliads; at least one of which is the new species, I think. B. zacapensis has front, less webbed toes than B. helminthi.

Ranito, Sean 2007 Journal May 6 Laguna Chupala, Ndean chupala, Rasto, Chequirima, Jutiapa, Guatemala (cont) ... we should have taken. We parked on the W side above a small village and walked ~45min up; it was fairly steep and extremely hot. There is thick scrub all the way up to the top on this side. We had to wait at the CONAP guard station while they found someone to accompany us - it is a reserve and they were rather particular about our permits. Our guide didn't seem to care as we sat down some of the many bromeliads in cypress near the entrance, where I found a Schlunzia stauferi. We then went to the lower shore where we cut down many bromeliads but found nothing. This area has big trees with more huge bromeliads than I have ever seen. We ate lunch and then walked to just above the mirador, where I found 2 more Schlunzia in big bromeliads as it rained lightly. We walked over to the wetter, N-facing south shore and searched in bromeliads first in the natural broadleaf forest and then in the extensive area of planted cypress, but found nothing more. In all, we searched from 12:00-17:00 and probably opened >100 bromeliads. It seems like some species of salamander must be here, although perhaps not, given the extreme isolation of this forest. We could see Volcan Suchitan to the SW - this seemed like a great place to work. Gustavo said Manuel Acevedo found a Boldoglossa sp. there. This entire area needs much more exploration and I hope that I can return to Ndean Chupala. It's an incredibly beautiful place. On the way back, we collected a Bufo lutkenii in the town near Julio Vargas' house.

Roiter, Sean 2007 Journal May 7 Aldea Pinalito, in mountains E of Zacapa, Depto: Zacapa, Guatemala For our last day of the trip, we tried to get to an area in the mountains east of Zacapa where the map shows a dirt road goin near 1700m. We set out early, drove through Zacapa to La Frementia, and then took a dirt road that branched off to the left at a creek. We drove on this road, which was awful, for ~40 min until we arrived at a locked gate, where we had to stop. We could see forested mountains from here, but apparently the land is all private. We need to get better maps. We drove back down, got better directions, and went on another dirt road that goes out of La Frementia to Matanzas. The road climbs steeply and soon enters oak and then pine forest. We eventually reached a puesto de salud, and continued straight until we arrived at Aldea Pinalito, where there is a mission run by Americans - Michael and Rocky Boone (52058135 - cell, 24311160 - house, [email protected]). They told us that the trail off for Matanzas is at a soccer field near the puesto de salud, and that it goes up to the cloud forest. They also told us that we could walk up to the forest in 30 min. We quickly checked some red banana trees in the area of their health clinic and found 4 B.rufescens. We left a big log with some kids who seemed willing to search more and walked up a steep path out of town through cattle pasture with 41 boys from the village. It was extremely hot and it took us, more like 45 min to get to an area on top of the ridge where the forest begins. We worked in a small, rather
Page 245
Rivita, Sean 2007 Journal May 7 Aldea Limaito, mountains E of Zacapa, Dept: Zacapa, Guatemala (cont) isolated fragment and another area just on the edge of the forest. The cattle pasture seems to meet primary cloud forest here, and we could see many big trees in the forest. There were areas of the ridge much higher than where we were that looked spectacular. We searched in bromeliads (including the 4 boys to varying degrees) and found many salamanders in a short time (16:00-17:40). Carlos, Ted and I, boy Daniel, found 2 B. Rufescens, 3 B. cranti and 2 black Salamanders that may be Bolenni in the more isolated fragment, while Mustafa, 2 boys and cl found 1 B. Rufescens, 1 B. cranti and 1 B. dunni (?) on the edge of or in the cloud forest. I think we could have found many more salamanders if we'd had more time. There should be both B. delfini and C. mangina here, and the loasted hills seem like a better place to look for Cryptotriton Othan at da Union, which we could actually see to the E on the way up. Our guides told us that there is a hut of some sort (apparently w/no roof) where one can stay in the forest. This seems like a very exciting place for future work. We walked down, since it was near dusk, and found out that the kids (4 & 5) had collected 6 more B. Rufescens in town for a total of 10. This is the most salamanders in a day on this trip, with little effort. We drove back to Zacapa in the dark and took swabs for chytrid from the salamanders we collected at the upper site. This was a great end to the trip for me.

Photo, Dean 2007 Journal May 21 Donora Pass, Inyo Co. and Owens Valley, Inyo Co., CA Dean Schiitle and I drove up to Donora Pass to get salamanders for my physiology experiments. I immediately found 2 in seeps below the road [illegible] near the 7000 ft sign. Both were small adults or subadults (SP Phys 1+2). We walked up to the cascade where I found many in 2005, but it was covered in snow. We walked back to some small trickles of water on a west-facing slope above the small creek that leads to the road, a spot where Dean got some swals for me. We found 2 more subadults/small adults (SP Phys 3+4) by turning status along the wet areas, and saw about 5 juveniles. In all, we searched for ~40 min here. We drove down to the Owens Valley lab in Bishop, where we are staying. After dinner, we went to Charlie Canyon, where the habitat was very dry except under the biggest rocks and along the stream. We found 5 big adults (ChC Phys 1-5) and 4 juveniles between 20:00 and 20:30; one adult was foraging along the stream and all the others were under rocks. Finally, we went to Sawmill Canyon. After some pointless bushwacking due to my confusion about where we were, we arrived at the place where I found salamanders last year. It was fairly wet in the seeps along the cliff wall, and I found 6 adults (tore 5-5m C1-5) and 4 juns here; it was very dry everywhere else. I also collected an Elyaria multicarinata from the branches of a shrub. We searched from 21:30-22:30, but only spent 10-15 min in the good salamander habitat.

Kanto, Dear 2007 Journal Silver Creek, White Mtns., Kings Cr. and Lake George, Mammoth Lakes Basin, Mono Cr., CA May 22 I spent the morning trying to regulate the temperature on the fridges and environmental chamber for my physiology experiments. Then we drove up to Silver Creek in the White Mtns. N of Bishop. We parked where the road turns N away from the stream (37.40112°N, 118.22158°W [WGS84], 6m acc.), 2491m elev. and searched here for ~30 min. There are lots of birch trees along the creek, which has a good flow of water. I found some good looking spots for Batrachoseps, with rocks and moist leaf litter similar to the B. sample site at Barrel Spring, but didn't find any. We ate a quick lunch and then walked upstream, stopping to search at 2 spots. Both looked good - I had a small cascade and the other had limestone with moss and leaf litter. These seem like good Batrachoseps habitat. We searched a bit at the point where the canyon branches (37.39684°N, 118.21114°W [WGS84], 7m acc.), 2496m elev. and then headed back. In all we searched from 12:30 - 16:30. After dinner, we drove to Lake George, where it was quite snowy. We found 2 juvenile and 1 adult male R. platycephalus in ~15 min of searching in the seep, and Sean found an icecrawler and a Helixia on the draw. When we got back to OVL, I found that 4 of 5 salamanders from Charlie Canyon that I put in the small fridge were frozen. One wasn't totally frozen and recovered completely. Another was frozen and slowly regained the ability to move. The last two were dead, and I had to preserve them (SMR246+247). I put all the salamanders at 15°C - can't trust the small fridges.

Harris, Dean 2007 Journal Olancha Creek, Inyo National Forest, Inyo Co., CA June 1 I drove along the LAOWP canal behind Olancha and parked where it meets the creek. I started at 11:45 and hiked up on the N side of the creek (much easier than other side) to near the mouth of the canyon. I climbed up the steep slope north of the canyon mouth to a small saddle and then tracked down on the other side to the creek. The creek is impassable starting from the mouth, so this is the only way in. I started climbing up the creek and searching. I got to a spot where there was a damp, mossy/dirty area next to the creek that may have seeps also or it in wet periods. I found 1 juvenile and 3 adult H. platycephalus here under rocks (36.26535°N, 118.07087°W [WGS84, 2Gm acc.], 1719m elev.) at 15:09 and collected 2 adults (SMR255+256). Continuing up the creek, there are some nice cascades and mossy seep areas that look like perfect habitat. I found another adult H. platycephalus under a rock along the stream (36.26461°N, 118.07266°W [WGS84, 11m acc.], 1760m elev.) at 15:40. Continuing up, I got to an area with willow covering an area along the stream, with some rocks sitting in leaf litter. I found a subadult (SMR257) and a juvenile Batrachoseps holbrooki under 2 of these rocks, as well as 2 juv. H. platycephalus under the same rock about 1m away from the Batrachoseps rock (36.26482°N/118.07347°W [WGS84, 7m acc.], 1779m elev.). A short distance upstream, I found a big adult Batrachoseps and a juvenile Hydromantes under the same rock! (SMR258). A bit up upstream, I found 2 juvenile Hydromantes under a rock on a big granite exposure along the stream at 16:40, at which point I stopped searching and headed back.
