CRLF Monitoring

A biologist evaluates the size and health of this CRLF to ensure long-term survival.

Mitigation credits are currently available at Ridge Top Ranch. We are available to discuss your mitigation needs for impacts to these federally-listed species and their habitat: California red-legged frog (CRLF) and Callippe silverspot butterfly (CSB).

The Ridge Top Ranch Wildlife Conservation Bank, approved in late 2014, is a 745-acre conservation bank in Solano County, California. The bank is approved by U.S. Fish and Wildlife Service to offer credits for both species as single or combination (dual) credits.

CRLF were successfully translocated to the habitat. There are 13 stock ponds and a large riparian corridor on the property suitable for CRLF breeding and non-breeding hydration habitat. The uplands provide suitable aestivation and dispersal habitat for CRLF. Habitat is being enhanced with native wetland plantings. Furthermore, the uplands support extensive nectar and larval host plants (Viola pedunculata – California golden violet {aka Johnny jump-up}) for the CSB. The property hosts an extensive amount of nectar plants, larval host plants, along with ridgelines and hilltops suitable for dispersal and mating. CSB has been documented onsite consistently over the last 11 years.

Mitigation credits from the bank can be offered during formal and informal consultation with the U.S. Fish and Wildlife Service for impacts to CRLF and CSB.
