P092: Effectiveness of Reintroductions and Probiotic Treatment as Tools to Restore the Endangered Sierra Nevada Yellow-legged Frog

The Sierra Nevada yellow-legged frog (Rana sierrae) is a special status species that was historically abundant in the central and northern Sierra Nevada, including the Lake Tahoe Basin. As a consequence of its precipitous decline, it is increasingly the focus of conservation and restoration efforts led by both federal and state agencies. The project provides critical information and guidance on the effectiveness of frog reintroductions as a means to reestablishing R. sierrae populations in areas from which they were previously extirpated.
