As a Conservation Scientist at WCS, Jon is the Connectivity Initiative Coordinator for the North America Program. As Principle Investigator or Co-PI on several projects in the Greater Yellowstone Ecosystem, the Sierra-Nevada, Great Basin, and other regions of North America, Jon’s current research and conservation portfolio includes: 1) examining impacts of natural gas development on pronghorn; 2) protecting ungulate (pronghorn, moose and elk) migrations by understanding and reducing impacts of wildlife-vehicle collisions and rural residential sprawl in migration corridors; 3) investigating and reducing human-bear conflicts along the wildland-urban interface; 4) using resource selection modeling, Brownian Bridge models, and circuit theory modeling to examine connectivity for large carnivores and ungulates; 5) examining impacts of the border fence along the US-Mexico border on wildlife connectivity (jaguars and other species); and 6) understanding how human-altered environments impact cougar ecology, behavior and population dynamics.
Along with >40 publications, Jon is lead editor on a book titled Safe Passages: Highways, Wildlife and Habitat Connectivity. Jon has given over 60 scientific meeting presentations and over 40 invited university and professional training presentations. His research has been the subject of more than 100 radio, television, and newspaper features including NBC Nightly News, Discovery Channel, NY Times, LA Times, Newsweek, National Geographic, and The Wall Street Journal. Jon applies science to affect conservation through the public policy arena; for example, his collaborative field research motivated the $9.7M construction of under- and overpasses on a Wyoming highway to provide the Path of the Pronghorn migration safe passage across the road, and his published research and outreach on human-bear conflicts prompted new bear-resistant dumpster laws and ordinances in several counties in California and Nevada.
