Using the existing rangewide genetic and demographic data, scientists from the USGS, USDA Forest Service, and University of Waterloo will assess the relative contributions of habitat and genetic connectivity to lek size and stability.

Prioritizing landscapes for sage-grouse habitat conservation is complicated by long-term changes in climate.

USGS and Colorado State University scientists are modelling multispecies connectivity through intact and disturbed areas of the sagebrush landscape.

USGS and Colorado State University scientists will use data about sage-grouse and mule deer population data across Wyoming to evaluate the effectiveness of disturbance thresholds and investigate the efficacy of other disturbance metrics.

USGS and Colorado State University scientists are using data and hierarchical community models to create predictive surfaces of bird use by habitat type and comparing these predictions to habitat prioritization derived from sage-grouse locations.

Little is known about the role of fire in the sagebrush ecosystem within the range of the Gunnison sage-grouse ( Centrocercus minimus), and fire has been mostly absent from these systems in the 20th century, partially owing to active fire suppression.

USGS scientists are using a time-varying approach to monitor and predict recovery of sagebrush ecosystems following disturbance.

USGS led an interagency team of Federal and State agency biologists to develop a report that synthesizes greater sage-grouse scientific literature.

The USGS is developing science and decision support tools to inform policy and management decisions about various aspects of the energy development life cycle.

There is a well-known bias in the location of protected areas both within the US and globally. Lands protected for conservation tend to be located on less productive soils at high elevations far from cities. USGS is exploring whether this ‘high and far’ paradigm applies within protected areas as well. That is, does human modification within lands that already have some degree of protection, also...

There is increasing support for adopting landscape approaches to resource management, including monitoring threats that affect multiple resources across broad extents. However, there remains a need to assess potential threats to individual species of conservation concern. USGS is evaluating the extent to which a generalized indicator of terrestrial development can be used to inform and evaluate...

Ecological integrity describes the condition of ecological systems, and has been quantified in aquatic systems for decades. The U.S. Forest Service is now required to monitor ecological integrity, and the Bureau of Land Management has an interest in doing so as well. As a result, USGS is working to define and quantify the concept of ecological integrity in terrestrial, multiple use landscapes to...
