Bats in Forests Managed for Wildlife

The Challenge: Within the Mississippi Alluvial Valley (MAV), forest managers may prescribe variable retention silvicultural treatments within bottomland hardwood forests on public lands to improve forest conditions (i.e., structural heterogeneity, species composition, and senescence) for priority wildlife species. This is referred to as wildlife-forestry silviculture. However, concerns have...

Mississippi Alluvial Plain (MAP): Water Availability Study

The Mississippi Alluvial Plain is one of the most productive agricultural regions in the Nation and depends on groundwater for irrigation. The MAP area constitutes the third largest area of irrigated cropland in the United States. The area is approximately 29,000 square miles (19 million acres) and includes parts of the States...

Structure maps of the Carrizo-Wilcox aquifer in northwestern Louisiana

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

Hurricane Information

Hurricanes bring destructive winds, storm surge, torrential rain, flooding, and tornadoes. A single storm can wreak havoc on coastal and inland communities and on natural areas over thousands of square miles. In 2005, Hurricanes Katrina, Rita, and Wilma demonstrated the devastation that hurricanes can inflict and the importance of hurricane hazards research and preparedness.

Ozark Groundwater Availability Study

The U.S. Geological Survey's Groundwater Resources Program (GWRP) is conducting an assessment of groundwater availability throughout the United States to gain a better understanding of the status of the Nation's groundwater resources and how changes in water use and climate may affect those resources. Assessments will be completed for the Nation's principal aquifer systems to help characterize...

Developing Techniques for Estimating Nutria (Myocastor coypus) Abundance

Nutrias (Myocastor coypus) are an aquatic rodent imported from South America to the United States in the 1920-40’s for the fur farms. Since their original importation they have become established in the wild in many regions of the United States.

Poisoning of Migratory Birds at Contaminated Sites

The Challenge: The Department of the Interior (DOI) and the National Oceanic & Atmospheric Administration are trustees for a wide variety natural resources that belong to all Americans. Additional natural resources are overseen by Native American tribes, states, and other federal agencies. Migratory birds are an example of a trust species for DOI, under the US Fish and Wildlife Service....

National Park Service Visitor Spending Effects

The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...

Using Quantile Regression to Investigate Ecological Limiting Factors

Unexplained heterogeneity in statistical models of animal responses to their physical environment is reasonable to expect because the measured habitat resources are a constraint on—but not the sole determinant of—abundance, survival, fecundity, or fitness. The ecological understanding and reliability of management predictions based on animal habitat models can be improved by shifting focus ...
