Forgues Slide and Bear Creek tributary, Mariposa Co., CA
Jed Papenfuss and cl left Berkeley at 11:00 and drove to Mariposa to do our final survey of the Forgues-Ruckslide for Caltrans. It rained last night into this morning, so the moss and soil at the site were reasonably wet. We searched the east side of the habitat on the S side of the river from 15:30-18:30 but cl found only 3 B. discolores. There is a huge amount of messy talus above where cl found the H. brunnia last time that looks quite good. After dinner, we walked up the trail near the E edge of the slide and searched from 20:30-23:00 with lights. Jed found 3 H. brunnia out foraging in relatively dry areas near mossy rocks - one was in some dry leaf litter. We collected the two largest - an adult female (SMR 207) and a subadult (SMR 208) (37.65544N, 119.90174W [WGS 84], 10m acc.), 515m elev.). cl took the third one to swab, and will return it tomorrow:
# FS1 (Forgues Slide) subadult B+V photo 1040137
cl also saw 1 Jaricha tarsa sorriae, 1 Eriothrix. xanthoptica,
and 1 B. discolores out foraging.
On the way back to Mariposa, we stopped at the tributary of Bear Creek where cl put my (missing) data logger. clm about 15 min. cl found 3 H. brunnia in the culvert, which cl swabbed:
BC1 age: adult type: B+V photo: 1040140
BC2 subsadult -> 1040141
BC3 juvenile -> 1040143
The temperature was in the 50s today and in the 40s at night.
