North American Bat Monitoring Program (NABat)

Bats are essential contributing members of healthy, functioning ecosystems. They perform numerous ecosystem services like insect pest control and plant pollination, and provide enormous economic benefits through ecotourism, medical research, and novel biotechnologies. North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, and wind energy...

USGS Chronic Wasting Disease Research at NOROCK

Chronic wasting disease (CWD) is a growing management issue in the U.S. and has been detected in 36 states as of April 2025, including many western states. There is no cure or vaccine for CWD, and the disease threatens economically important animals like elk and deer. NOROCK scientists have taken a multi-pronged approach to develop actionable science including 1) evaluating CWD management options...

Deriving Spatial and Temporal Waterfowl Inputs for Disease Risk Modeling

USGS is creating spatially and temporally explicit inputs to improve avian influenza transmission risk modeling. This project places special emphasis on wild bird distribution and abundance models as well as avian influenza prevalence models.

USGS Chronic Wasting Disease Research at the National Elk Refuge

Over the past 20 years, chronic wasting disease (CWD) in Wyoming has been spreading slowly outward from the southeastern corner of the state into the Greater Yellowstone Area and Wyoming's elk feed grounds. CWD detections have been getting closer to the National Elk Refuge, which provides supplemental feeding to approximately 8,000 elk and 500 bison each winter. NOROCK scientists have been...

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 36 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 36 states and four provinces and in captive cervid facilities in 22 states and three provinces.

The influence of natural mineral licks on wildlife disease dynamics

Some locations on the landscape can aggregate animals of multiple species and could become hotspots of disease transmission. One example of this are areas of localized concentrations of minerals that animals like deer, elk, bighorn sheep, and mountain goats use and diseases like chronic wasting disease or respiratory diseases could spread among or within species who use natural mineral licks...

Understanding Avian Influenza Exposure and Antibodies in Understudied Species

Recent outbreaks of highly pathogenic avian influenza have impacted a dramatically wider range of bird hosts than ever before. USGS researchers are working to identify which bird species have been exposed, which have developed immune responses, and how these species may influence viral ecology to inform risk management activities.

Using Telemetry to Understand Overlap in Habitat Use Between Waterfowl and Agricultural Birds in North America

USGS researchers are using telemetry to improve our understanding of how wild birds move throughout their environments and the potential implications for disease transmission within and to domestic poultry.

Avian Influenza Spread, Prevalence and Persistence

USGS researchers seek to understand the factors influencing the spread and persistence of avian influenza viruses on the landscape. This research also addresses how novel strains of highly pathogenic avian influenza are impacting a larger number and diversity of host species, including waterfowl, shorebirds, raptors and other birds.

Avian Influenza Host Movement Ecology

Understanding disease systems requires an understanding of the basic ecology of host species. USGS is involved in global efforts to explore the movements of bird species that are hosts of avian influenza as well as the potential impacts of changing landscapes on avian influenza.

Advancing Risk Modeling for Highly Pathogenic Avian Influenza

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. Researchers at the USGS Eastern Ecological Science Center have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and...
