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.
