Sagebrush-Associated Species

The Greater Sage-grouse Population Monitoring Framework fills a prominent information gap to help inform current assessments of sage-grouse population trends at nested spatial and temporal scales. It is centered on four objectives: (1) create a standardized database of lek counts; (2) develop biologically based spatial population structures by clustering leks; (3) estimate spatial trends at...

Long-term wildlife monitoring is imperative for understanding population changes that can inform managers. However, working with population data collected by different organizations across multiple jurisdictions and over long time periods can be challenging due to varying data management approaches and organizational priorities. Through this project, we aimed to collaborate with eleven state...

Greater sage-grouse ( Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits and their role as an ecological indicator for the health of sagebrush ecosystems. Multiple science centers with the U.S. Geological Survey (USGS) in conjunction with Colorado State University (CSU) have developed the Greater Sage-Grouse...

Researchers at the U.S. Geological Survey (USGS) and Colorado State University (CSU) collaborated with the Bureau of Land Management and state wildlife agencies to develop a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus) populations and the sagebrush ecosystems they depend on for survival and reproduction. This greater sage-grouse...

Land and wildlife managers require accurate estimates of sensitive species’ trends to help guide conservation decisions that maintain biodiversity and promote healthy ecosystems. Multiple science centers with the U.S. Geological Survey (USGS), in conjunction with Colorado State University (CSU), developed a hierarchical population monitoring framework for managing greater sage-grouse (...

The sagebrush biome is one of the largest ecosystems in North America. Encompassing nearly one-third of the continental U.S., it provides critical resources for millions of Americans and a home for hundreds of plants and animal species in the West. Natural resource management in sagebrush ecosystems can be complex, and science can support management decisions by providing knowledge and tools to...

The Wyoming Landscape Conservation Initiative (WLCI) addresses the impacts of land-use and habitat changes on Southwest Wyoming’s natural resources. This long-term project involves partners from 12 Federal, State, and local natural resource agencies, as well as non-governmental organizations. NOROCK scientists, partners, and scientists from other USGS centers conduct integrated research to support...

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...

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...

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...

Diseases are challenging to manage in wild ungulate populations, particularly when there are many ways the disease can spread. Wildlife management agencies often need to take action to control disease spread, but it is unclear which actions are most effective in constraining disease because the importance of different spread mechanisms is not fully understood. This project will aid state wildlife...
