Rare East Side Salamanders

Two salamander species are found in the Bishop BLM Field Office jurisdiction: Hydromantes platycephalus (Mount Lyell salamander) and Batrachoseps campi (Inyo Mountains slender salamander). Both species are California Species of Special Concern and B. campi is a BLM Sensitive Species.

Hydromantes platycephalus was discovered accidentally in 1915 in pitfall traps set to survey mammals on Mt. Lyell in Yosemite. Salamanders in the southern portion of the range in Long and Owens Valleys were believed to be a different species but were recently shown to be the same (Rovito 2010). Found from 4,000 to 12,000 feet, a couple individuals have been located on BLM lands. I am yet to find one, but hope to by resurveying the locations.

Batrachoseps campi wasn't discovered until 1973 and is only known from 16 canyons and springs in the Inyo Mountains. The canyons are difficult to survey, with steep, rocky waterfalls I had a hard time getting up. Fortunately, at one location I found an individual beneath a rock at the foot of a steep face. Nothing like locating a rare salamander to make a biologist's day!
