Patricia Valcarcel

Wildlife Biologist


Patricia Valcarcel earned a MS in Wildlife Sciences while conducting research on the spatial ecology of the threatened giant gartersnake. She has worked on a variety of field research projects ranging from animal movements to behavior and reproduction. She has presented her work at many conferences and published in peer-reviewed journals.

Patricia has extensive experience working with giant gartersnakes in the Sacramento Valley and assisted with mark-recapture surveys for San Francisco gartersnakes in San Mateo County. She has performed surveys and other activities related to California red-legged frog in Alameda, San Mateo, Los Angeles, Solano, and Sonoma Counties. Patricia has also led trapping and relocation for Pacific pond turtle.  She also has extensive experience throughout California’s Central Valley including protocol-level surveys for Swainson’s hawk, burrowing owl, and assessments for San Joaquin kit fox and blunt-nosed leopard lizard.  In addition, she has conducted observations and coordinated compliance for Pacific herring spawning in San Francisco Bay.

Patricia’s primary responsibilities are to conduct surveys, habitat assessments, and write associated biological assessment and technical reports for special-status wildlife species.  She has experience with the San Joaquin County Multi-Species Habitat Conservation Plan as one of the on-call biologists for the San Joaquin Council of Governments.  In addition, Patricia is involved in environmental permitting, permit compliance, and mitigation and monitoring efforts associated with these permits.
