Sage-grouse

In partnership with the United States Fish and Wildlife Service, and other partners, scientists from USGS Fort Collins Science Center are working to create a suite of prioritization scenarios that will inform adaptive management for Gunnison sage-grouse.

In 2021, the Fort Collins Science Center initiated a research effort to 1) assess how traffic in Wyoming has impacted sage-grouse population growth rates, 2) identify the spatial scales at which these effects are most evident, and 3) identify what levels of traffic result in sage-grouse population declines.

In 2021, the Fort Collins Science Center initiated a research effort to estimate road age and annual traffic volumes across the majority of roads in Wyoming for assessing impacts to wildlife. Data on roads often focus on the ‘where’ (for example, spatial features) but neglect the ‘when’ (for example, road age) or ‘how much’ (for example, traffic volume). Knowing these characteristics is critical...

Roads and their associated infrastructure can cause substantial and pervasive effects on adjacent ecosystems but are necessary for the movement and redistribution of goods, people, wealth, and natural resources in modern societies. The Fort Collins Science Center has initiated research looking at how roads and traffic may be impacting sagebrush ecosystems and the wildlife inhabiting them. This...

We are working with Colorado Parks and Wildlife (CPW) to pilot an expansion of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET; Duchardt et al. 2021) across northwestern Colorado. We are in the initial phase of a two-phase project where we are leveraging existing data resources to provide customized scenarios that directly guide landscape-scale conservation delivery by CPW. This...

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)...

Arid shrublands of western North America face growing threats from disturbances such as wildfire, drought, and invasive species. These threats are increasingly altering the sagebrush (Artemisia species) biome and degrading habitat for species of conservation concern such as greater sage-grouse (Centrocercus urophasianus). Effective management and restoration are needed to slow or reverse these...

Wildlife management is frequently conducted to benefit a single species, despite evidence that suggests such an approach often fails to adequately address the needs of other species within a region. Managing for multiple species’ habitat requirements is even more critical when large scale habitat management efforts change vegetation conditions at the landscape scale, or when management occurs at...

To support strategic ecosystem management across the imperiled sagebrush steppe in Wyoming, USA, we developed an extension of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET). Our expanded tool leverages emerging spatial data resources to provide a structured but customizable set of scenarios that can guide landscape-scale planning efforts by prioritizing conservation and...

We are using existing datasets that span broad spatial and temporal extents to model the efficacy of invasive annual grass treatments across the sagebrush biome and the influence of environmental factors on their success. The models we develop will be used to generate maps of predicted treatment efficacy across the biome, which will be integrated into the Land Treatment Exploration Tool for land...

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 spatial...

USGS researchers are using remote-sensing and other broadscale datasets to study and predict recovery of sagebrush across the sage-grouse range, assessing influence of disturbance, restoration treatments, soil moisture, and other ecological conditions on trends in sagebrush cover. The results will be used to inform conservation prioritization models, economic analyses, climate change projections...
