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.

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 ...

North American Waterfowl Management Plan

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats. Without this information, NAWMP population, habitat, and people objectives may not reflect stakeholder and societal values; and management...

Status and Trends of Emergent Wetlands in the Northern Gulf of Mexico: 1950-2010

Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide a plethora of resources including plant and wildlife habitat, commercial and recreational economic activity, water quality, and natural barriers against storms.

Mapping Marsh Structure with Polarimetric Radar: Highlighting Change in Oil Spill Impacted Marshes

While the historic focus of vegetation condition is the bulk live and dead compositions, these variables provide no information on the structure of vegetation (density and orientation). Canopy structure information is critical for monitoring status and trends, and essential in climate, weather, and ecological studies.

Oil Spill Samples Arrive from Louisiana

On April 20, 2010, the Deepwater Horizon Drilling Platform exploded and sank, causing the largest oil spill yet recorded. Samples from the oil spill were collected by Louisiana USGS scientists Greg Swayze and Charlie Demas and sent for analysis in Menlo Park, CA. The Louisiana samples were discovered on several of Louisiana's barrier islands, including Grand Isle, a large
