In The Nature Conservancy’s California Chapter, Mark provides scientific leadership and guidance by developing analytical approaches to planning, conservation strategy development and monitoring. He is currently studying the relationships between water management, compatible agriculture and conservation of the Pacific Flyway.
Prior to joining the Conservancy, he was the Executive Director of Field Station Programs at San Diego State University. Prior to that, he worked for the University of California’s Natural Reserve System as Co-Director of the Sedgwick Reserve near Santa Barbara and as Co-Manager of Sagehen Creek Field Station for the University of California, Berkeley. He also worked as a wildlife biologist in Tahoe National Forest for the U.S. Forest Service. He holds a Ph.D. in Zoology/Animal Biology from the University of California, Berkeley and an M.S. in Zoology/Animal Biology from Idaho State University.
