Unified Interior Regions

Montana

Welcome to the Midwest Region! Our region includes 18 Science Centers in 11 States from the Great Lakes to the Dakotas, south to Missouri and Kentucky. Our streamgage network is used to monitor and assess water resources across the region. Other research focuses on fisheries and aquatic ecosystems, midcontinental plant/animal species, invasive species, wildlife disease, and energy and mining.

Amphibian Research and Monitoring Initiative: Rocky Mountain Region

The Rocky Mountain Region of Amphibian Research and Monitoring Initiative (ARMI) encompasses Montana, Wyoming, Colorado, and New Mexico. Two USGS Science Centers initiate and develop ARMI projects in this region. Investigations at NOROCK are headed by Dr. Blake Hossack. Investigations at the Fort Collins Science Center (FORT), Colorado, are headed by Dr. Erin Muths. The ARMI program is based...

Climate Change in Mountain Ecosystems (CCME)

Climate change is widely acknowledged to have a profound effect on the biosphere and cryosphere with many and diverse impacts on global resources. Mountain ecosystems in the western U.S., and the U.S. Northern Rocky Mountains in particular, are highly sensitive to climate change. Warming in western Montana is nearly 2 times greater than the rise in global temperatures over the last 100+ years...

Fishery biologists and managers are increasingly consumed with the recovery and restoration of native trout and salmon throughout the western United States. These fish historically inhabited a variety of freshwater habitats, but have declined due to habitat degradation, fragmentation and introduction of nonnative species. Introduced fishes constitute a major threat to the persistence of native...

Predicting Effects of Climate Change on Native Fishes in Northern Great Plains Streams

The Northern Great Plains of North America are a region of profound global importance because organisms that live in these semi-arid prairie environments have developed a unique ability to live through conditions of extreme heat, cold, floods, and drought. Prairie streams are essential components of these ecosystems because they provide critical “green lines” of habitat for both aquatic and...

Estimating Future Streamflow in Eastern Montana Using the Precipitation-Runoff Modeling System and the RegCM3 Regional Climate Model

Streams in the Northern Great Plains provide critical “green lines” of habitat for aquatic and terrestrial wildlife. However, changes in water quantity associated with global climate change may transform some prairie streams from essential refuges to habitats no longer capable of supporting fishes. Although studies have examined climate change effects on larger river basins across the United...

Drivers of Drought in the Upper Colorado River Basin

The purpose of this project is to investigate Colorado River basin droughts, and the role of temperature in influencing runoff efficiency. The project uses paleoclimatic data to extend instrumental climate and flow records, along with projected warming to assess the range of possible conditions that may be expected to occur and to determine how warming temperatures may influence river flow and...

Extinction dynamics and microrefugia of the American pika as climate changes.

Accurate projections of climate change and associated impacts on wildlife are now essential to conservation planning, but predictive models of range shifts for many species are often coarse, ignore extinction dynamics, and overestimate suitable habitat. Recent studies suggest the American pika (Ochotona princeps) is vulnerable to increasing heat stress in the Great Basin yet appears more...

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.

Predicting changes in Bear Foods

Huckleberries are central to the diets of bears, grouse, and other animals, as well as being a cultural and food resource for humans. Approximately 15% of the diet of bears in the Whitefish range and Glacier National Park is huckleberries, and huckleberries help bears gain weight for hibernation. Changes in climate lead to changes in vegetation phenology, productivity, and quality that may...
