The Blunt-nosed leopard lizard (Gambelia sila) is an endangered and charismatic lizard species native to California’s Central Valley. In partnership with The Bureau of Land Management and the Telemeco Reptile Ecology and Evolution lab at California State University, Fresno, emergency permission was granted to collected adult G.sila (4 male and three female) from the Panoche Hills plateau. This colony was taken to Fresno Chaffee Zoo to form the first captive assurance colony of G.sila. Since the 2020 collection the program has produced over 60 lizards and have produced F2 animals. Our presentation will review our program successes, challenges and the future of our work this species.
