Sagebrush and Sage Grouse

Greater sage-grouse ( Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems. Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) worked with the Bureau of Land Management (BLM) and state wildlife agencies to develop a...

Scientific information is fundamental to understanding how proposed actions on public lands may impact the environment. Development of new science is occurring at rates that can make it challenging for biologists, resource managers, decision makers, private landowners, and other stakeholders to ensure they are using up-to-date, high-quality science information to inform their decisions. Further...

FORT researchers provide sound science to support the Department of the Interior in its efforts to streamline reliable energy development, enhance cost efficiency in public lands management, and manage fire-prone habitats for public safety. This research is developed in partnership with resource managers from local, State, Federal and Tribal governments, industry, and nongovernmental organizations...

In recent decades, wildfires have increased in size and intensity, and the fire season has lengthened. This and other factors have increased wildfire suppression costs and risks to human health and safety. Economists in the Social and Economic Analysis Branch (SEA) at FORT investigate numerous aspects of wildland fire, its impacts, and how to mitigate the risk wildfire poses to people, resources...

WebDART is an online ecological assessment tool available to a wide audience that incorporates Landsat satellite remote sensing imagery, topography, geology, soil conditions, and rangeland geospatial and vegetation mapping to compare altered terrain with an unspoiled area that has similar characteristics in the same region. The tool gives resource managers, landowners, companies, and other...

The USGS has initiated a new collaboration effort with Department of War (DoW) in the sagebrush biome. The goal of this effort is to establish a network with DoW resource managers to define pervasive natural resource issues facing DoW installations and to identify existing innovative USGS science and tools that support DoW resource managers. Through this effort, the USGS will provide subject...

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.

Encompassing over 175 million acres, America’s “Sagebrush Sea” is the largest terrestrial ecosystem in the lower 48 states. A predominately shrubland system, this landscape ranges over deserts, valleys, mountains, and mesas from the Canadian border to our southwestern deserts. The sagebrush ecosystem – the ancestral homeland of many Tribal Nations – supports critical agricultural and recreation...

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...

Invasive annual grasses are spreading across the sagebrush ecosystem, threatening the survival of native plant species and the wildlife habitats they support. Researchers from the U.S. Geological Survey, Colorado State University, University of Wyoming, the Bureau of Land Management, National Park Service, and the U.S. Fish and Wildlife Service are collaboratively investigating the factors that...

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, facilitated by a range of disturbances, are invading many areas within the sagebrush biome. Researchers from the U.S. Geological Survey, Colorado State University, U.S. Fish and Wildlife Service and the Bureau of Land Management are investigating which non-fire disturbances are most associated with the spread of invasive grasses. The findings from this study could guide...
