The fisher is a rare forest carnivore whose West Coast population has been proposed for listing under the federal Endangered Species Act. Using field and laboratory techniques, we’ve discovered the most common cause of mortality for fishers is predation by larger carnivores, mainly bobcats and mountain lions. These three carnivores coexist in California forests and likely have complex relationships that range from competition for food, predation, possibly to indirect benefits. The investigation of the story of these three predators continues. Dr. Wengert is assistant director and ecologist for Integral Ecology Research Center, a non-profit research organization dedicated to wildlife conservation, and is also a lecturer at Humboldt State University. Greta earned her B.S. in Wildlife Biology at Cornell, her M.S. in Wildlife Ecology at HSU, and her Ph.D. in Ecology at UC Davis. Most of Greta's research focuses on interactions among species and uses both a molecular approach to identifying predator species and disease, and a field approach to describe habitat overlap and spatial interactions between species. A Native Predator Zone, featuring these species, is a featured part of the Zoo’s master plan.
