The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native sagebrush, grasses, and herbaceous flowering plants that provide habitat for many native animals, including Greater Sage-Grouse. Changes in vegetation and fire management have been suggested with the intent of conserving Greater Sage-Grouse. However, the potential responses of other sensitive-status birds to these changes in management...

We are seeking to better understand networks among resource managers with respect to developing plans for climate change adaptation. We are pursuing this through a network analysis based on a survey of federal resource management staff and scientists in the southwestern and Midwestern U.S. Originally planned, this study was conceived to cover the Southwest and North Central Climate Science Centers, as defined by the USGS. In practice, surveys are most easily distributed within regions as defined by the federal resource agencies. Unfortunately, there is no uniform set of regions. We have tried to be comprehensive in our survey and cover at least the North Central and Southwestern Region.

High-frequency observations of surface water at fine spatial scales are critical to effectively manage aquatic habitat, flood risk and water quality. We developed inundation algorithms for Sentinel-1 and Sentinel-2 across 12 sites within the conterminous United States (CONUS) covering >536,000 km2 and representing diverse hydrologic and vegetation landscapes. These algorithms were trained on data from 13,412 points spread throughout the 12 sites. Each scene in the 5-year (2017-2021) time series was classified into open water, vegetated water, and non-water at 20 m resolution using variables not only from Sentinel-1 and Sentinel-2, but also variables derived from topographic and weather datasets. The Sentinel-1 model...

Climate change is altering the patterns and characteristics of fire across natural systems in the United States. Resource managers in the Southwest are faced with making natural resource and fire management decisions now, despite a lack of accessible information about how those decisions will play out as fire regimes, and their associated disturbances, will change across the landscape. Decision makers in natural-resource management increasingly require information about projected future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An accessible and forward-looking summary of what we know about the “future of fire” is urgently required in the Southwest and across the country...

Actionable science has evolved rapidly over the last decade, and the Climate Adaptation Science Center (CASC) network has established itself as a leader in the field. The practice of actionable science is generally described as user-focused, action-oriented science that addresses pressing real-world climate adaptation challenges. It is also sometimes referred to as usable science, translational ecology, and coproduction. Successfully carrying out actionable science projects requires a range of skills, mindsets, and techniques in addition to scientific knowledge. Those skills can include mutual learning with stakeholders, attention to social and political context, iterative creative problem-solving, and interdisciplinary...
