Brad McRae

Senior Landscape Ecologist

Brad McRae is a senior landscape ecologist for The Nature Conservancy’s North America Region. He provides science support for large landscape-scale conservation projects, and conducts research on climate change adaptation, wildlife corridors, restoration planning, and conservation genetics. Brad pioneered the use of circuit theory to model connectivity and gene flow across fragmented landscapes, garnering coverage in media outlets like Wired Magazine and Conservation Magazine. He leads development of Circuitscape and Linkage Mapper, two software packages that help conservation planners around the world design wildlife corridors and healthy landscapes.

Brad received his Ph.D. from Northern Arizona University and his M.S. from the University of Wisconsin-Madison, and holds an affiliate assistant professor position at the University of Washington’s School of Environmental and Forest Sciences. He studied mountain lion populations for his Ph.D. before doing postdoc stints at the US EPA in Corvallis, Oregon, and the National Center for Ecological Analysis and Synthesis (NCEAS) in Santa Barbara. Brad lives in Seattle with his wife, where they enjoy hiking, skiing, canoeing, and biking.
