Sagebrush and Sage Grouse

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.

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.

Invasive annual grasses, such as cheatgrass ( Bromus tectorum ) and medusahead ( Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Fire rehabilitation programs have existed within federal agencies since the early 1960s. The U.S. Forest Service and Bureau of Land Management are the largest users of emergency stabilization and rehabilitation (ES&R) funds, but these agencies only sporadically implement proposed monitoring and rarely use common protocols. As a result, it is impossible to draw scientifically credible conclusions...

Fuel breaks have the potential to minimize catastrophic losses of sagebrush habitat and sage-grouse populations by altering fire behavior and facilitating fire suppression. However, they may carry risks to sage-grouse populations—of habitat loss, fragmentation, cheatgrass (Bromus tectorum) invasion, and alteration of sage-grouse movements—that have not been quantified.

Recent analyses of greater sage-grouse genetics have delineated areas of key genetic connectivity for this species and provided a prioritization tool for conservation and restoration of habitats essential for genetic exchange.

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.

Understanding potential changes in ecological, social, and climate systems can help managers and decision makers take actions to ensure that natural landscapes and human communities remain healthy and are able to provide essential ecosystem services now and in the future.

Lidar has proven itself as a valuable tool for providing high-resolution digital elevation models and for quantifying forest stand metrics utilized by the forest industry. Studies are only beginning to emerge relating lidar data directly to wildlife species occurrences and abundances. NPWRC has been assessing capabilities of lidar data in various ecosystems to include the mixed forests in Maine...
