Interagency Grizzly Bear Study Team

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 as a direct result of controversy surrounding the closure of open pit garbage dumps within Yellowstone...

Science in Glacier National Park

Glacier National Park (GNP) is considered a stronghold for a large diversity of plant and animal species and harbors some of the last remaining populations of threatened and endangered species such as grizzly bear and bull trout, as well as non threatened keystone species such as bighorn sheep and black bear. The mountain ecosystems of GNP that support these species are dynamic and influenced by...

Western Waters Invasive Species and Disease Research Program

Researchers at the Northern Rocky Mountain Science Center's Western Waters Invasive Species and Disease Research Program work extensively with federal, state, tribal, regional, and local partners to deliver science to improve early detection and prevention of invasive species and disease; understand complex interactions that promote invasive species and disease, and their impacts (and associated...

Long Term Research in northwest Montana

The Northern Continental Divide Ecosystem (NCDE) in northwest Montana is one of the last strongholds of the grizzly bear in the lower 48 states. Of the six established grizzly bear recovery zones, the NCDE is the third largest in area, potentially harboring the greatest number of grizzly bears, and is the only zone contiguous to a strong Canadian population. However, little information exists...

Grizzly Bear Dispersal

This work has two components. First, we developed a method to use our family tree data to examine dispersal. Next, we would like to apply this method to our updated and more complete family tree to improve our understanding of how grizzly bears disperse.

Grizzly Bear Family Tree

Building a family tree of grizzly bears can both satisfy our natural curiosity about bear society and answer many ecologically important questions about the ways bears interact with each other and the landscape.

American bullfrog suppression in the Yellowstone River floodplain

The American bullfrog (Rana catesbeiana) has recently invaded backwater and side-channel habitats of the Yellowstone River, near Billings, Montana. In other regions, bullfrog invasions have been linked to numerous amphibian declines (e.g., Adams and Pearl 2007). Immediate management actions may be able to suppress or eradicate localized populations of bullfrogs because they are present at low...

An investigation of aquatic invasive species in pristine sites in the Greater Yellowstone Area

Aquatic invasive species (AIS) are aquatic organisms that move into ecosystems beyond their natural, historic range and cause severe and irreversible damage to the habitats they invade. Most AIS arrive as a direct result of human activity, such as boating and angling. The threat of AIS introduction is especially high in the Greater Yellowstone Area, as humans from all over the world come to see...

Predicting climate change impacts on river ecosystems and salmonids across the Pacific Northwest: Combining vulnerability modeling, landscape genomics, and economic evaluations for conservation

Salmonids – a group of coldwater adapted fishes of enormous ecological and socio-economic value – historically inhabited a variety of freshwater habitats throughout the Pacific Northwest (PNW). Over the past century, however, populations have dramatically declined due to habitat loss, overharvest, and invasive species. Consequently, many populations are listed as threatened or endangered under the...

Genetic status and distribution of native westslope cutthroat trout in Glacier National Park

After 14,000 years of surviving extreme environmental events, such as floods, fires and glaciations, Glacier’s greatest native trout is at high risk of disappearing from several streams and lakes east and west of the Continental Divide. The decline of westslope cutthroat trout (Oncorhynchus clarkii lewisi; WCT) in Glacier National Park (GNP) has been attributed to the establishment of nonnative...
