Jerre has worked with CBI for 16 years as a conservation ecologist in endangered species research and landscape-scale conservation planning and management of natural resources in the U.S., Europe, and Mexico. She is passionate about developing and orchestrating partnerships among the academic community, government agencies, non-governmental organizations, and land managers to leverage funds and information for achieving conservation goals. Throughout her career, Jerre has researched and developed priorities for conservation and funding in California and Baja California, resulting in the acquisition and management of hundreds of thousands of acres for conservation, including the 240,000-acre Tejon Ranch in the Tehachapi Mountains, Donner Summit and Martis Valley in the Sierra Nevada (>15,000 acres), >100,000 acres in San Diego County, and Bahía de San Quintín in Baja California (>5,000 acres). She is project director for the Las Californias Binational Conservation Initiative which promotes creation of a binational park along the Peninsular Ranges of California and Baja-California. She has directed conservation planning, management, and monitoring for California’s Natural Community Conservation Planning programs in southern California, developed a regional program for coordinating management and monitoring in San Diego County, and currently works with land managers and researchers to develop management and monitoring plans for these programs. She coordinated development of the population monitoring framework for the six subspecies of Island Fox on the California Channel Islands and, through a grant from the David and Lucille Packard Foundation, developed a science-based regional planning framework for wind energy in the Tehachapi Mountains and southern Sierra Nevada. She serves as a science and education advisor for several land trusts. As a member of the board of Terra Peninsular, she is active in conservation in Baja California.
