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)
