Remote Sensing Tools Advance Avalanche Research

The USGS Snow and Avalanche Project (SNAP) uses remotely sensed technologies to understand snowpack changes that influence water storage, recreation, avalanche hazard and acts as a driver of landscape change. Satellites, uninhabited aerial systems (UAS), and structure-from-motion (SfM) photogrammetry are some of the tools scientists use to collect high resolution imagery that supports ongoing snow...

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...

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...

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...

Yellowstone Lake Acoustic Biotelemetry Project Home Page

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...

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 resilient...

Evaluating the linkages between regional climate patterns, local climate data, and native Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and non-native brook trout (Salvelinus fontinalis) growth, survival, and life-history expressions.

Beyond large-scale climate models, it is becoming increasingly important to quantify how regional climate patterns link with in situ stream temperatures and hydrologic regimes and concomitantly, fish behavior, growth, and survival. Here, we are using comprehensive mark-recapture techniques to evaluate how changing climatic conditions are likely to influence native westslope cutthroat trout and non...

Bighorn Sheep in and near Glacier National Park

USGS collected GPS data as well as genetic and other samples on over 100 bighorn sheep east of the Continental Divide in Glacier National Park, Waterton National Park, and the Blackfeet Reservation. Bighorn sheep across the west are vulnerable to disease such as pneumonia. We are therefore working to improve our understanding of bighorn sheep movements, approaches for monitoring bighorns, and...

Ecology of Elk on Department of Interior Lands in Southwest Wyoming

Between 2005 and 2010, we radio- collared 61 female elk (Cervus elaphus) on Fossil Butte National Monument and 12 female elk near Cokeville, Wyoming, slightly northwest of the Monument, all from the West Green River herd. We are using the 209,250 locations from these elk to identify seasonal distribution patterns, evaluate habitat use, and assess factors influencing the timing of migration...

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...
