Return of the Yellowstone Grizzly Bear
Yellowstone grizzly bears inhabit federal, state, tribal, and private lands, and long-term research requires careful coordination across governmental levels. The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 and today’s members include representatives from the U.S. Geological Survey, National Park Service, U.S. Fish and Wildlife Service, U.S. Forest Service, the Eastern Shoshone and Northern Arapaho Tribal Fish and Game Department, and the States of Idaho, Montana, and Wyoming. This interagency approach ensures consistency in data collection and allows for combining limited resources to address information needs throughout the GYE.
The study team, now led by the U.S. Geological Survey, has conducted research on this the Yellowstone grizzly bear for over 40 years, perhaps the largest collection of scientific information on any bear species in the world. This video highlights what decades of science tell us about this charismatic species and its conservation.
The USGS provides the unbiased science needed to manage America’s natural resources and to help endangered and threatened species recover.
The USGS led Interagency Grizzly Bear Study Team is part of the USGS Northern Rocky Mountain Science Center. The center is part of the Northwest Region of the USGS. Scientists from the Center work in the northern Rocky Mountains of the United States and across the U.S. Many of their scientists work throughout the world on issues as diverse as global climate change, aquatic ecology, wildlife diseases, bison ecology, and large carnivores.
