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.
