The California red-legged frog Rana draytonii has been declining across its native range since the 1960s and was considered extirpated from most of southern California. In February 2017, a population of R. draytonii was re-discovered in the San Bernardino Mountains of Riverside County, California, where it has not been documented since 1959 (LACM 91074). This population belongs to a mtDNA lineage thought to be extinct from this species within the United States but still extant in Mexican populations. This discovery increases the potential for future, evolutionarily-informed translocations within the southern portion of this species range in California.
