Range-wide population trend analysis for greater sage-grouse (Centrocercus urophasianus)—Updated 1960–2025 Range-wide population trend analysis for greater sage-grouse (Centrocercus urophasianus)—Updated 1960–2025

Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) are at the center of State and national land-use policies largely because of their unique life-history traits as an ecological indicator for the health of sagebrush ecosystems. This updated population analysis provides State and Federal land and wildlife managers with the best available science to help guide...

Mountain lion prey-selection in a community comprised of native and introduced ungulate species Mountain lion prey-selection in a community comprised of native and introduced ungulate species

Species introductions are a hallmark of human influence on ecosystems worldwide. In communities where native and introduced fauna coexist, predators may select prey based on availability or vulnerability. Free-roaming feral horses (Equus caballus) are a recent addition to North America and have become widespread, abundant, and in some areas serve as major prey for mountain lions (Puma...

Data Harmonization for Greater Sage-Grouse Populations

Long-term wildlife monitoring is imperative for understanding population changes that can inform managers. However, working with population data collected by different organizations across multiple jurisdictions and over long time periods can be challenging due to varying data management approaches and organizational priorities. Through this project, we aimed to collaborate with eleven state...

Actionable science for managing public lands

Our team of biologists, ecologists, and social scientists focuses on coproducing actionable science products to support natural resource planning and management. Broadly, our research involves working to better understand and bridge the research-management gap through a variety of mechanisms, including coproduction and relationship-building, science synthesis and summary, and identification of...
