Climate change-induced warming can alter plant phenology and disrupt ecosystems like the sagebrush steppe in western North America. The invasive annual grass cheatgrass can thrive under these altered conditions, exacerbating wildfires and threatening wildlife habitat, carbon storage, and other important ecosystem services. We are studying how different densities of cheatgrass respond to increased...

City of Rocks National Reserve and Craters of the Moon National Monument and Preserve are lands managed by the National Park Service that contain ecologically valuable stands of sagebrush and unique forest communities that are at risk due to wildfire and invasion by exotic annual grasses. We are working to determine the extent of invasion and to provide park managers with wildfire risk assessments...

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...

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...

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.

Climate forecasts provide a unique tool to researchers and wildlife managers, allowing for a look into potential future climate conditions. Climate models provide multiple scenarios that assume different mitigation polices implemented by governments. By using these data in a statistical model to estimate soil-climate conditions, we can investigate the connection between future climate and...

Researchers from the U.S. Geological Survey are developing a strategic framework for assessing and monitoring the impacts of fuel breaks in sagebrush ecosystems of the western U.S. Fuel breaks are increasingly being used to reduce the threat of wildfire, but more information on their efficacy and impacts on wildlife habitat and exotic annual grass invasion is needed.

In Alaska, increased wildfire activity has been linked to warming temperatures. Summers with extreme wildfire activity threaten life and property, clog the air with smoke, and challenge the state’s wildland firefighters. While the largest fires are often started by lightning and burn in remote areas, these fires require significant resources to fight when they threaten life and property. Increas

In 2017, California was experiencing its most severe drought in over a millennia. Low rainfall and record high temperatures resulted in increased tree mortality and complete forest diebacks across the West. Though land managers scrambled to respond, they lacked information needed to make informed decisions. Focusing on California’s central and southern Sierra Nevada Mountains, this project seeks t
