Biologist places camera trap in a brush pile on San Joaquin River NWR

Jaime Rudd, director of the Endangered Species Recovery Program, places a camera in a large brush pile on the San Joaquin River NWR where two riparian woodrats were recently captured in humane traps. The woodrats had not been observed for more than 8 years on the refuge, so the discovery was surprising. The camera trap study aims to help the refuge learn more about the elusive woodrat and its habitat needs.
