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...

Bombus aff inis, the rusty patched bumble bee, was federally listed as an endangered species in 2017 and has been identified as one of the top priority species for recovery nationally. Shortly after listing the species, the U.S. Fish and Wildlife Services and other partners prioritized the research needed to prevent the extinction of B. affinis . Some of the top research needs that were identified...

Bison have played a key role in shaping the grasslands of the Great Plains for millennia. National Parks are a major last bastion for wild herds of the national mammal and symbol of the Department of the Interior. However, even as the National Park Service aims to maintain as natural as possible ecosystem conditions within its parks’ boundaries, managers regularly make decisions affecting their...

Applying quantitative methods to evaluate ecological hypotheses for wild animal populations is inherently challenging due to the complexity of ecological systems and the sampling process that is used to monitor them.

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.

A USGS forecasting tool helps Everglades natural resource managers identify management actions that can benefit one or more species while quantifying the potential costs to others.

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...

The Joint Ecosystem Modeling (JEM) team will develop species distribution models that incorporate hydrologic and habitat variables known to influence Cape Sable Seaside Sparrow occurrence.

Ecosystem management and assessment of rivers requires detailed data on bathymetry before estimates of aquatic habitats can be determined. However, mapping bathymetry in shallow rivers is challenging due to river depth limitations for watercraft.

USGS is working with partners to understand how the federally protected Florida manatee population changes over time and responds to threats.

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.

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.
