Sagebrush and Sage Grouse

Biological soil crusts (biocrusts) are a community of living organisms, like moss, lichen, and algae, covering soils in arid and semi-arid ecosystems, providing important ecological functions like carbon cycling and soil stabilization. Analyses show that biocrusts are negatively associated with the abundance of invasive annual grasses that are responsible for increasing fire across the Great Basin...

Sage-grouse, iconic birds of the American West, have experienced dramatic reductions and fragmentation of habitat, resulting in significant conservation concern. Genetic information can help inform priorities for protection and habitat restoration as well as strategies for translocations, but may be difficult for resource managers to find, interpret, and use in their decision making. In this work...

Greater sage-grouse ( Centrocercus urophasianus) management relies on the identification and protection of core habitat for the species. Core areas are often centered on leks where the potential impacts of anthropogenic development and other disturbances can be evaluated based on buffer distances around active leks. While buffer distances have been quantified for some regions, sage-grouse space...

Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) worked with BLM and State Wildlife Agencies to develop a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus) populations and the sagebrush ecosystems that they depend upon for survival and reproduction. This hierarchical population monitoring strategy now...

Sagebrush ecosystems and sagebrush-dependent wildlife species are likely to experience more frequent extreme drought and temperature conditions with changing climate. Greater sage-grouse ( Centrocercus urophasianus), an indicator species in sagebrush ecosystems, may experience habitat and population losses that are increasingly exacerbated by current and future climate change. However, the direct...

Land and wildlife managers require accurate estimates of sensitive species’ trends to help guide conservation decisions that maintain biodiversity and promote healthy 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 hierarchical population monitoring...

To support the Department of Interior's bureaus, states, and local communities, we are developing 1) a document highlighting remote sensing approaches that can be leveraged for site prioritization, recovery design, and long-term assessments of recovery trends, and 2) data products of vegetation conditions, change, recovery potential, and risk of exotic plant invasion on mine lands. We will...

Resource management decisions need to be informed by up-to-date, quality science and data. However there is sometimes an overwhelming number of scientific publications for managers to consider in their decisions. This project provides concise summaries of recent, peer-reviewed science and data products about different resources and topics of management concern, integrated into a searchable tool.

This project analyzes on-the-ground plant monitoring data across sagebrush and rangeland ecosystems to examine how fire, climate, topography, and plant communities influence the success of invasive annual grasses after fires.

The National Environmental Policy Act (NEPA) requires federal public land managers to assess potential environmental impacts of proposed actions. The USGS, Bureau of Land Management, US Fish and Wildlife Service, Colorado State University, and North Central Climate Adaptation Science Center are working together to develop science syntheses that can facilitate considerations of climate change in...

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.

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...
