Patricia Valcarcel, CWB®

Senior Biologist

Overview

Patricia Valcarcel is a Senior Biologist with WRA, Inc. and leads the company’s regulatory practice group. She has a wealth of experience in both wildlife biology and wildlife regulations.  Patricia’s focus is reptile and amphibian species, but she has broad experience with wildlife species in northern California and California’s Central Valley including Swainson’s hawk and burrowing owl. She earned an MS degree in Wildlife Sciences while conducting research on the spatial ecology of the threatened giant gartersnake, and has worked on a variety of field research projects ranging from animal movements to behavior and reproduction. Patricia also leads training on collection of samples for environmental DNA (eDNA) analysis and implemented this method for detection of giant gartersnake in project planning.

Patricia blends her knowledge of wildlife into permitting complex projects involving special-status species and advises on project design to reduce impacts and improve the approval process. She is one of WRA’s leading Habitat Conservation Plan (HCP) experts and is currently working on an amendment to the Clark County, Nevada Multi-Species HCP for their Desert Conservation Program. She leads an on-call service contract with the San Joaquin County Multi-Species Habitat Conservation and Open Space Plan (SJMSCP). Patricia consults with both federal and state wildlife agencies and prepares federal Section 7 Biological Assessments, federal Section 10 HCPs, and California Incidental Take Permits for complicated and long-term projects.  In addition, Patricia provides oversight of complex environmental permitting, permit compliance, and mitigation and monitoring efforts associated with these permits.
