Patricia Valcarcel, CWB®

Senior Biologist

Overview

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 conferences and published in peer-reviewed journals. She is also trained on a variety of sampling techniques including collection of samples for environmental DNA (eDNA) analysis and implemented this method for detection of giant gartersnake. The results are used in combination with other methods to help inform on presence of the cryptic species.

Patricia has extensive experience working with and permitting for special-status species in California. Her focus is reptile and amphibian species, but has broad experience with wildlife species in California’s Central Valley.  Her primary responsibilities are to conduct habitat assessments, prepare associated technical reports and permit applications, and consult with wildlife agencies on special-status wildlife species. She consults with both federal and state wildlife agencies and has prepared federal Section 7 Biological Assessments, federal Section 10 Habitat Conservation Plans, and California Incidental Take Permits for complicated and long-term projects.  In addition, Patricia is involved in environmental permitting, permit compliance, and mitigation and monitoring efforts associated with these permits.
