A user-friendly decision support tool for monitoring and managing greater sage-grouse populations

Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) developed 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 serves as a foundation for future...

Southwest Energy Exploration, Development, and Reclamation (SWEDR)

Approximately 35% of the US and approximately 82% of DOI lands are “drylands” found throughout the western US. These lands contain oil, gas, oil shale, shale oil, and tar sand deposits and the exploration for and extraction of these resources has resulted in hundreds of thousands of operating and abandoned wells across the West. These arid and semi-arid lands have unique soil and plant communities...

New Tools for Modern Land Management Decisions

In an era of rapid land use changes and shifting climates, it is imperative that land managers and policymakers have actionable and current information available for decision processes. In this work, we seek to meet these needs through new data products and decision support tools built on digital soil mapping, new vegetation cover maps, agency inventory and monitoring data sets, and cutting-edge...

Changes in Sagebrush Ecosystem Connectivity

Disturbances, management, and changing environmental conditions have reshaped the sagebrush biome within the western United States. As a result, sagebrush cover and configuration have varied over space and time, influencing ecological processes and species' use of the landscape. Characterizing changes in sagebrush ecosystem connectivity over time will help us understand the effects of those...

Ecosystems We Study: Coastal

Coastal ecosystems provide critical local and national societal benefits such as coastal protection and fish nurseries but are some of the most heavily used and threatened systems on the planet. The Mangrove Science Network is a collaboration of USGS scientists focused on working with natural resource managers to develop and conduct mangrove research.

Ecosystems We Study: Alaska Bioregions and Arctic

Alaska is simultaneously a landscape of extremes requiring specialized adaptations by plants and animals to survive the winters and a landscape of abundance that supports breeding birds each summer from as far away as Africa. Terrestrial Alaska also supports iconic species such as caribou and muskoxen whose population dynamics, predator/prey relationships and habitat ecology are researched by USGS...
