The yellow-blotched salamander (also known as the
yellow-blotched ensatina) is a medium-sized, brown to black
nocturnal salamander that is found only in a very narrow range in
South-Central California. It is one of seven subspecies of
Ensatina eschscholtzii,
each of which is found in a
limited
range in mountains and foothills encircling California's
Central Valley. The yellow-blotched ensatina occupies one of
the smallest of these ranges; it's limited only to the Tehachapi Mountains and extends into the Los Padres
National Forest in the vicinity of Mt. Pinos, Frazier
Mountain and Alamo Mountain.
As with
many different salamanders and other amphibians, the
yellow-blotched salamander prefers to inhabit cool, moist
places, under the soil, under debris, or near water. It
remains underground during hot and dry periods as well as
during cold or very severe weather, and is most active
during wet or rainy nights. The salamander breeds during the
fall and spring and
possibly throughout the winter, and lays its eggs
underground or under debris, such as bark or rotting logs.
The young salamanders are fully-formed when hatched.
On Alamo
Mountain the yellow-blotched salamander inhabits a very
narrow band of the forest, where the geology is such that
there is an abundance
of rock outcrops and springs, with corresponding moist soil
and vegetation for cover. The salamander also thrives on the
old growth nature of this
forest, using fallen and
rotting logs for hiding out in dry
weather
and laying its eggs.
While the impact on the
species from the 2006 Day Fire is not completely understood,
fire most certainly has a negative impact on this species by
not only killing those that can't burrow deep enough, but
also by removing the fallen vegetation on which the animals
depend.
As Alamo
Mountain recovers from the effects of the 2006 Day Fire, the
remaining salamanders in the area are now more vulnerable to
further disturbance, such as the proposed salvage logging
operation along Alamo Mountain road. The presence of this
species on Alamo Mountain is one reason ForestWatch is
encouraging the Forest Service to conduct an Environmental
Assessment before beginning their logging operation.
