Greater Yellowstone Ecosystem

Greater Yellowstone refers to an enormous core of protected federal lands and private lands in three states including and surrounding Yellowstone National Park. This region is home to a rich variety of flora and fauna such as the Trumpeter Swan, Grizzly Bear, Gray Wolf, Bison, and Whitebark Pine. Fish and wildlife managers in this area also face threats from brucellosis and whirling disease.

UGSG logo The USGS Northern Rocky Mountain Science Center (NOROCK) is a key partner in the Greater Yellowstone region of Mountain Prairie because the center conducts research on natural resources in Montana, Wyoming, and Idaho. Much of this research takes place in the Greater Yellowstone Ecosystem. Projects include black bear demography, habitat modeling, amphibian surveys, bison management, plant ecology, and more.

Managing the Greater Yellowstone

GYCC logo

The Greater Yellowstone Coordinating Committee (GYCC) was formed to allow representatives from the National Park Service, U.S. Forest Service, and the U.S. Fish and Wildlife Service to pursue opportunities of mutual cooperation and coordination in the management of core federal lands in the Greater Yellowstone area. Go to the official GYCC website for information about the committee, their accomplishments, maps, and related resources.

CollapseBear Ecology in the Greater Yellowstone and Greater Glacier Ecosystems
Description: This site describes current research on grizzly bears in the Greater Yellowstone and Greater Glacier Ecosystems. In Glacier National Park, grizzly bears are studied using DNA taken from hair samples that were collected in the field. Researchers in Greater Yellowstone study bear-human interactions, current distributions, bear nutrition, use of whitebark pine, and other features of grizzly bear populations. Reports, publications, and remote camera photographs are available.

Species Spotlight

Whitebark Pine Tree

Whitebark Pine
Pinus albicaulis

Description: Whitebark pine is considered a keystone species in subalpine ecosystems because the survival of a large number of other species depends on its existence. It provides many ecosystem services: controlling runoff and erosion, influencing regeneration and succession, and providing a valuable food source.

Life History: Like most conifers, whitebark pine has wind-dispersed pollen. Seeds are dispersed by animals and birds, primarily the Clark's nutcracker (Nucifraga columbiana). The nutcracker has a mutualistic relationship with whitebark pine, and it relies on seeds from the tree as its primary food source.

Habitat: High-elevation, exposed sites near timberline

Distribution: Western United States and Canada

Status: In demise across their distribution due to fire suppression, mountain pine beetles, and an introduced blister rust
