Terrestrial Ecosystems
The Northern Rockies are blessed with an abundance of plant and animal species that have remained relatively intact since the Lewis and Clark expedition in the early 19th century. Expanding energy development, increasing human population pressures, and the continued demand on global water resources make the management of wildlife more complicated than ever. NOROCK works collaboratively with partners to study key life history and habitat needs of these species.

Evaluating Transmission of Chronic Wasting Disease in the Environment
Chronic wasting disease (CWD) is a fatal disease of deer, elk, and moose and has been spreading in North America for the past two decades. The disease is spread by infected body fluids. Animals can become infected by coming into direct contact with a CWD-infected animal, or an infected animal can leave behind fluids (e.g., saliva, urine) that an uninfected animal will come into contact later...
Quantitative Disease Ecology
Researchers at the USGS are working on developing new quantitative methods to study disease dynamics in wildlife systems as well as systems at the wildlife-domestic-human interface. Much of our work focuses on how host population structure affects disease invasion, persistence and control in wildlife disease systems. We tackle these issues with a combination of simulation and statistical modeling...
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...
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...
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...
Impacts of Disease on Wolves in Yellowstone National Park
In 1995 and 1996, wolves were reintroduced into the Northern Rockies where they have since established and spread. Within Yellowstone National Park, one of the core protected release sites, the unmanaged population steadily increased to high densities, producing a large wolf population susceptible to infections such as canine parvovirus (CPV), canine distemper virus (CDV) and sarcoptic mange.
Pneumonia in Bighorn Sheep
Bighorn sheep populations are often impacted by outbreaks of pneumonia that are suspected to come from domestic sheep and goats.
NOROCK Large Carnivore Research Program
NOROCK has substantial expertise in large carnivore research, primarily involving species listed as Threatened or Endangered. NOROCK’s Large Carnivore Research Program includes scientists from NOROCK’s Headquarters, West Glacier Field Station, and the Southern Appalachian Field Station. Studies are conducted in a wide variety of landscapes throughout the U.S., as well as international research...
Energy development and the airspace
Today, the alternative energy and telecommunications industries are developing the airspace much the way metropolitan growth and mechanized agriculture develop the landscape. NOROCK scientists and partners are using both historical and traditional technologies in new and innovative ways to observe wildlife behaviors in response to these changing habitats.
Seasonal Movement of Wild Hogs in Big South Fork National River and Recreation Area and Great Smoky Mountains National Park
The wild hog (Sus scrofa) is an exotic invasive species that significantly impacts native resources and their populations are expanding significantly throughout the United States. In addition, wild hogs are likely contributing to the spread of disease such as pseudorabies. National Park Service units in the Southeast that have populations of exotic wild hogs include Big South Fork National River...
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...
