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).
Bighorn Sheep and Mountain Goat Research in Western National Park Units
Mountain goat and bighorn sheep are iconic symbols of many national lands in the West. Both species have limited distributions that can be difficult to observe and face multiple stressors including disease, increasing recreation in remote areas, and shifting weather regimes that influence their forage and thermoregulation. As species with relatively small population sizes, understanding...
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. 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 hierarchical population monitoring...
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.
Northeast Amphibian Research and Monitoring Initiative
The U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.
USGS research on the effects of renewable energy on wildlife
Renewable energy development, such as solar and wind energy, is growing in the United States and is expected to continue expanding for the foreseeable future. However, renewable energy infrastructure can be a risk to some wildlife including threatened and endangered species. Wildlife managers and energy developers need wildlife risks to be assessed and effective strategies to mitigate those risks...
Decision Science Support for SARS-CoV-2 Risk to North American Bats
The Eastern Ecological Science Center is working closely with federal, state, and tribal partners to help inform decisions that reduce the risk of SARS-CoV-2 transmission from humans to North American wildlife, including bats.
Strategic Habitat Conservation for Brown Pelican
WARC researchers partnered with managers and species experts to develop a Bayesian network model and a geospatial habitat characteristics dataset to predict the number of Brown Pelican breeding pairs on islands in the northern Gulf of Mexico.
Decision science support for Chronic Wasting Disease
Eastern Ecological Science Center adds the decision analytical skill set to the existing body of USGS expertise on Chronic Wasting Disease (CWD), in support of our sister DOI agencies.
Understanding Avian Habitat Availability and Use After Barrier Island Restoration in Coastal Louisiana
Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.
