USGS Alaska Science Center Wildlife Tracking Data Collection

Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...

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) worked with BLM and State Wildlife Agencies to develop 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...

Hierarchical Population Monitoring Framework for Greater Sage-Grouse

Greater sage-grouse ( Centrocercus urophasianus ) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems. Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) worked with the Bureau of Land Management (BLM) and state wildlife agencies to develop a...

A targeted annual warning system (TAWS) for identifying aberrant declines in greater sage-grouse populations

Land and wildlife managers require accurate estimates of sensitive species’ trends to help guide conservation decisions that maintain biodiversity and promote healthy ecosystems.

Hierarchical Units of Greater Sage-Grouse Populations Informing Wildlife Management

Wildlife management boundaries frequently lack biological context, such as information on habitat resource availability and wildlife movements. To address this, we developed multiple levels of biologically relevant and hierarchically nested greater sage-grouse ( Centrocercus urophasianus ) population units that could facilitate management and conservation of populations and habitats.

North Pacific Pelagic Seabird Database

The North Pacific Pelagic Seabird Database (NPPSD) contains survey transect data designed and conducted by numerous partners primarily to census seabirds at sea. The NPPSD includes more than 486,000 transect segments and includes observations of over 20 million birds of 258 species collected over the span of 50 years (from 1973 to 2022).

Development and Implementation of Environmental DNA (eDNA) Tools to Aid Listing and Recovery Efforts for Imperiled and Common Freshwater Mussels

Researchers will develop and optimize an eDNA assay to delineate the current distribution of P. inflatus . The assay will then be used to provide up-to-date distributional information and detection rates for P. inflatus in the Pearl River basin.
