Foothill Yellow-legged Frogs (Rana boylii) are currently recognized as a California Species of Special Concern, a non-regulatory designation intended to focus attention on animals at conservation risk, stimulate research on poorly known species, and achieve conservation and recovery of these animals before they meet criteria for listing as threatened or endangered under the California Endangered Species Act (CESA; Fish and G. Code, § 2050 et seq.). Under the California Code of Regulations, Title 14, Section 670.5, the following FYLF designations have been made: Southwest/South Coast, West/Central Coast, and East/Southern Sierra clades are Endangered; Northeast/Northern Sierra and Feather River clades are Threatened. The Northwest/North Coast clade is not listed under the California Endangered Species Act but retains the status of California Species of Special Concern.
