Habitat Disturbance, Loss, or Degradation

Pollinators, including bees, flies, butterflies, bats, birds, and other animals, are critically important to U.S. ecosystems and agriculture. Recent reports of declines of pollinator species have led to widespread actions to conserve pollinator habitat and recover imperiled species, but resource managers need accurate data and science to support management actions. USGS pollinator research helps...

The SAGE Wildlife Research Group consists of a large team of research scientists with an interest in conservation and management of wildlife and their ecosystems. Broadly, research involves understanding animal-habitat relationships, with an emphasis on conservation ecology and population demography, and a focus on shrubland, alpine, and grassland ecosystems. We are addressing the effects of...

FORT researchers provide sound science to support the Department of the Interior in its efforts to manage wildfires, conserve water, reclaim public lands for multiple uses, and promote food security. This research is developed in partnership with resource managers from local, State, Federal and Tribal governments, industry, and nongovernmental organizations, empowering local and rural communities...

Wildlife movement and distribution can be influenced by local conditions like topography and landscape features, and the distances within which species respond to their landscape – scales of effect – can vary over space and time. We are estimating scales of effect for wildlife population trends to help land managers determine the distance within which wildlife will respond to landscape change.

Federal lands of the US contain important reserves of oil, gas and other resources important for Unleashing American Energy (SO 3418). After development of these resources is complete, successfully reclaiming disturbed lands is a necessary step towards restoring wildlife habitat, forage production, and maintaining natural resources for future use. To improve reclamation outcomes on these lands and...

USGS and Colorado State University researchers are conducting analyses and predictions of sagebrush recovery in the Great Basin and Wyoming and assess the role of weather, soils, and reseeding treatments.

This interdisciplinary project combines expert judgment on treatment costs with spatially explicit ecological modeling to estimate the financial resources needed to address the threat of invasive annual grass across the entire sagebrush biome. Results of the assessment will provide economic insights that can inform cost-effective resource allocation to efficiently achieve sagebrush conservation...

Through a collaborative effort with multiple state and federal agencies, university researchers, and individual stakeholders, we are producing a set of predictive seasonal habitat maps for greater sage-grouse ( Centrocercus urophasianus) spanning the entirety of the species’ U.S. distribution. This is the largest habitat modeling effort of its kind for the species and uses a large, compiled...

The Southwest Montana Sagebrush Partnership (SMSP) team, including land managers, landowners, and scientists, is implementing conifer removal projects encompassing over 55,000 acres of private, state, and federal lands throughout the region. To date, little place-based information exists regarding likely vegetation and bird responses to such treatments in Southwestern Montana. To address this...

Researchers at USGS are using historical wild horse survey and monitoring records to conduct a study of horse density across sagebrush ecosystems of the western United States. Researchers will develop generalized density maps for the species that will enhance concurrent evaluations into the ecological effects of wild horse populations.

Invasive annual grasses can replace native vegetation and alter fire behavior, impacting a range of habitats and species. A team of researchers from the U.S. Geological Survey, Colorado State University, the Bureau of Land Management, and the U.S. Fish and Wildlife Service are working to identify factors that influence changes in the distribution and abundance of invasive annual grasses (IAGs)...

Atmospheric nitrogen deposition, changing environmental patterns, and recreation are rapidly altering high elevation ecosystems. This project will evaluate long-term biogeochemical, hydrological, and ecological trends in Rocky Mountain National Park to understand the causes and rates of change in alpine and subalpine waters, soils, and vegetation. Resource managers of high-elevation, protected...
