In response to a petition to relist western gray wolves, USFWS concluded that relisting in the western U.S. was not necessary. The species status assessment included research from our Idaho Unit. Images: USGS.

Invasive American bullfrogs are a threat to wildlife in southeast Arizona, including some endangered reptiles and amphibians like Chiricahua leopard frogs & northern Mexican garter snakes. These bullfrogs can spread quickly and reproduce easily!.

We partner with the USGS Eastern Ecological Science Center and five National Wildlife Refuges where there is a high risk of Bsal, a newly emerging pathogenic fungus of amphibians. Our research may support management decisions for reducing these threats.

Boreal toads were once common in the La Barge Creek watershed in Wyoming but have experienced significant population declines. These declines are linked to habitat loss and infection by the fungal pathogen Batrachochytrium dendrobatidis. #amphibianweek .

The crawfish frog is rapidly declining across its range! This unique species lives primarily in upland habitats and relies on crayfish/mammal burrows. We are using radiotelemetry to track the frogs to better understand their habitat requirements.

Did you know that American bullfrogs are causing BIG problems for native wildlife in Arizona? These non-native frogs are a threat to species like the Chiricahua leopard frog and northern Mexican garter snake, which are already struggling to survive!.

The risks posed to amphibians by roads include vehicle collisions, habitat fragmentation, and barriers to seasonal movements. We are leading research to assess road risks and developing solutions in Iowa. #AmphibianWeek. Images: NPS and USGS

Bighorn sheep face threats due to M. ovi, a pathogen that causes respiratory disease. Discover our ongoing partnership with the Montana Department of Fish, Wildlife and Parks and the Wildlife Biology Program at the University of Montana. Images: USGS

Chronic wasting disease (CWD) is a fatal disease threatening deer throughout the U.S. It spreads naturally or though human activities. CWD has been detected in 34 states, with increasing risks of it entering Massachusetts. Image: USGS.

In 2022, U.S. residents spent $99.4 billion on fishing. Smallmouth bass fishing is important in WV and contributes to the economy. We are working with the WV Div. of Natural Resources to understand factors affecting the health of the fishery. Pics: USFWS.

Agrivoltaics is the use of land for both agriculture and solar energy production. While this approach has potential to lessen competition for land, it’s effectiveness and impacts on agroecosystems are not well understood. Images: USGS.

Solar is growing in the U.S., however the effects on birds are poorly understood. Information on the number of species and the presence or absence of birds may help managers monitor biodiversity, raise public awareness, and guide management. Pics: USFWS.

We are excited to release “A Hawk’s View of 2024” and “10-Year Overview.” The fact sheets highlight our program’s success in training of the next generation of natural resource professionals, applied research, and technical assistance. Images: USGS.

White-tailed deer are economically important in North Carolina as they generate revenue, support businesses and attract tourists. Our ongoing research helps determine how urbanization affects deer and the landscapes that support them. Pic: USDA

Wildfire can influence habitat conditions for mule deer, elk, mountain lions & black bears in New Mexico. We are helping to design better restoration treatments that reduce wildfires & improve habitat conditions for wildlife. Pics: Mountain lion, USGS.

In Navajo culture, the black bear holds deep significance, symbolizing strength, protection, and a connection to nature and the spiritual world. We are assisting the Navajo Nation in developing guidelines to manage human-bear interactions. Images: USGS

Recreational fishing is a billion-dollar industry that affects freshwater fish. We are leading efforts to understand fishing in small waterbodies in urban areas around Omaha, Nebraska. #wildlifeweek. Images: Walleye in net, USFWS; Walleye, USGS

Landscape change & pollution in Utah has led to habitat degradation--factors in bird decline. We are partnering with citizen scientists & data from eBird to help managers make informed decisions to support birds. Image: olive-sided flycatcher, USGS.

Moose populations in New England are experiencing reduced birth rates, caused by winter tick. In the early spring of bad years, it is common to see “Ghost Moose” which are skeletal, and nearly hairless.

It's #LearnAboutButterfliesDay! We depend on butterflies for fruits, vegetables, and other food crops. Pollinators in the form of bees, birds, butterflies, and bats also contribute to healthy wildlife, plants, and watersheds.
