Glaciers—Understanding Climate Drivers
Across the globe, glaciers are decreasing in volume and number in response to climate change. Glaciers are important for agriculture, hydropower, recreation, tourism, and biological communities. Loss of glaciers contributes to sea-level rise, creates environmental hazards and can alter aquatic habitats. These are among the cascading effects linked to glacier loss which impact ecosystems and human...
Western Bumble Bee and Native Pollinator Research
The western bumble bee was historically one of the most common bumble bees across the western U.S. and Canada. However, our research and others found it has declined substantially across its range and the U.S. Fish and Wildlife Service is considering it for listing under the Endangered Species Act. Bureau of Land Management, National Park Service, and other land managers need information to inform...
Remote Sensing and Fire Science
NOROCK science has developed capabilities for the remote sensing and evaluation of burns. Working with diverse institutions and individuals in fire science and information technology, we advance mutual interests of fire science partners by undertaking relevant research, and by disseminating findings through coordination and technology transfer.
Improving our understanding of forest-road effects on substrate in headwater streams of the Southwest Crown of the Continent
In 2010, Congress established ten decade-long Collaborative Forest Landscape Restoration Program projects to carry out fuel reduction and ecological restoration treatments on public lands across the country. The Southwest Crown of the Continent was selected as one of the locations under this initiative, given the importance of this region to the economic vitality of local communities and the...
Status of Glaciers in Glacier National Park
Glaciers on the Glacier National Park (GNP) landscape have ecological value as a source of cold meltwater in the otherwise dry late summer months, and aesthetic value as the park’s namesake features. USGS scientists have studied these glaciers since the late 1800s, building a body of research that documents widespread glacier change over the past century. Ongoing USGS research pairs long-term data...
Restoring Montana Pothole Wetlands - Demonstration Sites and Adaptive Management
Geologic processes from the last ice age have generated extensive areas of pothole wetlands in several Montana landscapes. The Laurentide ice sheet, originating in the Northwest Territories, provided the dominant force in eastern Montana. Similar landscapes developed in the broad valleys of western Montana through the actions of the Cordilleran ice sheet, originating in the mountains of British...
Identification of Fire Refugia in Rocky Mountain Ecosystems of the U.S. and Canada: Development and Application of the Refugium Concept for Biodiversity Conservation over Large Spatial and Temporal Scales
We described the climate space of fire regimes in northwestern North America (Whitman and others 2015), and we are refining an approach to identify fire refugia – areas that do not burn or burn with lower severity through multiple fire events. We continue our collaboration to test the function of refugia for biodiversity conservation under current and future climate and fire scenarios. We continue...

Assessing the impacts of mining in the Transboundary Flathead and Kootenai River systems
The Transboundary Flathead and Kootenai Basins in Montana and British Columbia host some of the most diverse and unique native aquatic ecosystems throughout North America. Headwaters of these basin feed into Waterton-Glacier International Peace Park (U.S. and Canada) and Flathead Lake, and Lake Koocanusa and the Kootenai River in the U.S. Despite the tremendous historical and ecological value of...
Evaluation of alternative dam operations on the movement and habitat use of bull trout and westslope cutthroat trout
The goal of this project is to quantify the operational impacts of Hungry Horse Dam on native bull trout and westslope cutthroat trout in the upper Flathead River system, Montana.
