Hell Hollow, Shadow Creek and N Fork Merced River, Mariposa Co, CA
Jan 7 and two adult H. lewisi (SMR 78+79) (37.58272°N,
120.05229°W [WGS 84, 10m acc.], 294m elev.). cl took 2
month swabs and photo vouchers for the other 8 H. lewisi,
and then released them. Conditions were very good today and
the moss was quite wet. This site appears to have a
large area of suitable mossy habitat on the stream bank
and along the road. We saw no limestone and all the
salamanders cl found were under shale.
We drove up 49 to Coulterville, through Brodley Hill to
the Bridging Rd and then 5 to a turnoff to the North
Fork of the Merced, heading to the junction of the N Fork
and Indian Dutch where Mike had found salamanders several
times before. We stopped a little (~500m) above the river
and flipped mossy shale rocks right along the roadside.
The vegetation was oak and chaparral, with a lot of damp
moss. We found 1" H. lewisi, 2 Ensatina eschscholtzii
xanthoptica, and 3 B. dialohus under the rocks between
about 4:15 and 5:30PM. Two of the H. lewisi were crushed
when we flipped rocks, so cl collected them (SMR 84+85). cl
also collected the Batrachoseps (SMR 87,88+89) and Ensatina (SMR
86 ) (37.65744°N, 120.05032°W [WGS 84, 9m acc.],
420m elev.). cl got month swabs and photo vouchers of the
other 6 H. lewisi. Once again, we saw only shale and no
limestone. The surrounding areas look very inhospitable to
salamanders, although the area of mossy hillside is quite
extensive and continues further up the road.
