Alternative future vegetation pathways reveal potential transformations of western US ecosystems Alternative future vegetation pathways reveal potential transformations of western US ecosystems

Managing ecosystems in an era of rapid change is inherently challenging not only because of uncertainty in future climate but also due to diverse responses of ecosystems to climate. Projections of ecological transformation alongside information about plausible vegetation trajectories can help land managers explore divergent scenarios and consider how modeled outcomes match their...

Monitoring nesting waterbirds for the South Bay Salt Pond Restoration Project—2024 breeding season Monitoring nesting waterbirds for the South Bay Salt Pond Restoration Project—2024 breeding season

The San Francisco Bay supports thousands of breeding waterbirds annually and hosts large populations of American avocets (Recurvirostra americana), black-necked stilts (Himantopus mexicanus), and Forster’s terns (Sterna forsteri). These three species have relied largely on former commercial salt ponds in south San Francisco Bay, which provide wetland foraging habitat and island nesting...

Evaluation of pathogen risks and testing considerations for Chinook salmon egg movements between New Zealand and California Evaluation of pathogen risks and testing considerations for Chinook salmon egg movements between New Zealand and California

Executive Summary Oncorhynchus tshawytscha (Walbaum in Artedi, 1792; Chinook salmon) were historically abundant in the McCloud River but are now extirpated from this tributary owing to dam construction and lack of passage. Planning efforts to restore populations above Shasta and Keswick Dams are currently underway, including an evaluation of potential source populations. One potential...

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...

Greater Sage-Grouse Population Monitoring Framework

Greater sage-grouse ( Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits and their role as an ecological indicator for the health of sagebrush ecosystems. Multiple science centers with the U.S. Geological Survey (USGS) in conjunction with Colorado State University (CSU) have developed the Greater Sage-Grouse...

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

Researchers at the U.S. Geological Survey (USGS) and Colorado State University (CSU) collaborated with the Bureau of Land Management and state wildlife agencies to develop a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus) populations and the sagebrush ecosystems they depend on for survival and reproduction. This greater sage-grouse...
