Central Owens Valley
Along the Owens River are extensive, large tree stands with other riparian vegetation. Such growth is also present around creeks draining the Sierra Nevada (Fig. 10.8). Along the Owens River many side pools provide breeding habitat for amphibians.
In this list only riparian-associated species are discussed. For other species in the area, refer to the southern White Mountains list (except for the Panamint Alligator Lizard, Elgaria panamintina , and the Gilbert Skink, Eumeces gilberti ).
