John C. Tull, Ph.D.
John Tull is the Assistant Regional Administrator for the Southwest Climate Adaptation Science Center (SW CASC), one of the nine regional centers that form the National and Regional Climate Adaptation Science Center network. He also serves as the Acting Sagebrush Ecosystem Coordinator for the USGS.
John’s career has centered around protecting native plants and animals, particularly looking at the interactions of humans and wildlife to find solutions that balance the needs of both in resource limited contexts. His academic degree work measured impacts of human activities on wildlife through a variety of research activities in Arizona, California and Nevada. In his prior role as the Nevada Science Coordinator at the U.S Fish and Wildlife Service, John facilitated partnerships and collaborations to advance science and strategic application of management decisions for the conservation of native wildlife and their habitats in rangeland and desert ecosystems across the Intermountain West. As the Assistant Regional Administrator of the Southwest Climate Adaptation Science Center, John now helps build science partnerships to address some of the broadest and most vexing natural resource challenges that are important for both wildlife and humans in the Pacific Southwest.
