Threats

USGS researchers assessed trends in non-native mammalian predator trapping methods designed to protect endangered ʻuaʻu and nēnē at Haleakalā National Park, Hawaiʻi.

Researchers are investigating the influence of Antimycin A on invasive carp and non-target fishes by measuring the effects of a novel species-specific bait formulation.

The Prairie Pothole Region (PPR) covers parts of five states and three Canadian provinces. The region contains millions of wetlands that annually produce 50-80% of the continent’s duck population. Previous modeling efforts indicated that climate change would result in a shift of waterfowl habitat from the central PPR to the southeast PPR where the majority of wetlands have been drained. However...

Changes in the body condition of a key forage fish species, Pacific sand lance ( Ammodytes personatus ), are examined to understand how energy transfer to predators may have been disrupted during the recent marine heatwave in the North Pacific (late 2013 to mid 2016).

The western bumble bee was historically one of the most common bumble bees across the western U.S. and Canada. However, our research and others found it has declined substantially across its range and the U.S. Fish and Wildlife Service is considering it for listing under the Endangered Species Act. Bureau of Land Management, National Park Service, and other land managers need information to inform...

South Florida's pine rockland ecosystem represents less than 3% of its original extent. This project will evaluate habitat conditions for two pine rockland snake species to develop future habitat condition scenarios for Species Status Assessments.

Southern Arizona’s semi-desert grasslands provides habitat for flora and fauna, regulates rainfall infiltration and overland flow, mitigates surface erosion and dust production, and sequesters carbon. Sustainable management is important to maintain these ecological services and is of concern for the managers, ranchers, and other people associated with the grassland. The Buenos Aires National...

Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.

National Wildlife Refuges provide habitat for important fish and wildlife species and services that benefit coastal communities, like storm-surge protection. USGS scientists are helping coastal refuges plan for and adapt to sea-level rise.

This research effort is an interagency partnership between U.S. Geological Survey and U.S. Fish and Wildlife Service to systematically explore the issues, viewpoints, and concerns within the Service in relation to conservation introductions. Conservation introduction is the planned, intentional moving of species, populations or genotypes to a location outside a target’s native range.

Migratory birds, and particularly those using habitats close to human settlements, may be infected with antibiotic resistant bacteria. The USGS is working with public health professionals to understand the role of birds in the maintenance and dispersal of antibiotic resistant bacteria. Additionally, the USGS is investigating how antibiotic resistant bacteria in birds may relate to public and...
