Alpine Vegetation Research

In 2003, USGS scientists joined the GLobal Observation Research Initiative in Alpine Environments (GLORIA) network in establishing vegetation plots at four alpine summits in Glacier National Park, MT, USA. Vegetation and temperature data collected at the GLORIA sites are used to understand trends in species diversity, composition, abundance, and temperature from climate sensitive alpine ecosystems...

Alpine Wildlife and Snowpack Dynamics in the North Cascades

Mountain ecosystems are expected to change with continued reductions in annual snowpack that have been observed worldwide over the past half-century. Recent snow droughts in North America have been attributed to unusually warm temperatures that cause winter precipitation to fall as rain, rather than snow. Many species of alpine wildlife depend on snowpack for insulation from extreme cold and for...

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...

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...

Wetland State-and-Transition Model Project

The Wetland STM project is creating a state-and-transition model to inform management of semi-permanently flooded wetlands in the Intermountain West and western Prairie Pothole Region, as well as designing a monitoring scheme to allow determination of current wetland condition.

Adaptive Capacity: the linchpin for understanding and addressing species vulnerability to climate-change impacts

When prioritizing natural resource management activities, managers need to understand how plant and animal species differ in terms of their vulnerability to variation in environmental conditions caused by climate change. Species vulnerability to climate change is controlled by (1) exposure to changing environmental conditions, (2) sensitivity to direct and indirect effects of those changing...

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...

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...

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...

Developing stream temperature networks for the Greater Yellowstone to aid in managing aquatic resources under a changing climate

The topographic diversity and extensive area of protected public land within the Greater Yellowstone demonstrate the importance of this region as a natural resource reserve. Understanding the effects of anticipated changes in climate on aquatic resources and means for managing these resources will ultimately require accurate linkages between empirical data and regional climatic patterns. This...

Forecasting the effects of climate change on the interactions of native and non-native salmonids

Changes in temperature and precipitation patterns under global climate change are expected to expand the range of suitable habitat for non-natives within stream networks, resulting in significant increases in the distribution and abundance of non-natives. However, our understanding of how landscape attributes can affect local thermal and hydrologic patterns suggests that changes in global climate...
