Brief Biography
John is Director of The Nature Conservancy's (TNC) Wildland Invasive Species Team. He is based in and has an unpaid appointment with the Department of Vegetable Crops & Weed Science at the University of California, Davis. John heads a small team that provides leadership, scientific support, information and advice on issues regarding invasive species, their prevention, and their control on Nature Conservancy sites and selected conservation areas across the U.S. and the other 23+ nations where TNC works. He also helps develop public policy approaches designed to prevent new invasions and minimize the spread and environmental damage cause by already established species with public agencies and private industries. John helped found the non-profit California Exotic Pest Plant Council (CalEPPC) and served as its first president in 1993 and '94 and served on the Board through 2000. John is on the Board of the Center for Invasive Plant Management based in Missoula, MT. and is also a member of the IUCN (World Conservation Union) Invasive Species Specialist Group and the steering committee for the U.S. Forest Service's Forest Health Technology Enterprise Team. He co-edited the books Invasive Plants of California's Wildlands (2000) and Invasive Plants: Weeds of the Global Garden (1996). John completed a Ph.D. in Ecology at the University of California, Davis in 1991. His research project focused on the biology and control of the non-native invader, bull thistle (Cirsium vulgare) in Yosemite Valley. He received an MS in Marine Science from Louisiana State University in 1986 and a BA from Cornell in 1982.
