What We Do

Prevention. Our specialists review environmental documents, legislation, regulations, and permits and licenses with pollution potential to ensure that harmful effects on fish, wildlife, and plants are avoided or minimized.

Some examples include:

  • analysis of documents and permits related to control of nonpoint source pollution from agriculture and urban runoff, point source pollution from industrial and municipal waste treatment facilities, and discharges of dredge and fill material;
  • review of proposed Federal projects related to mining, agricultural irrigation, range management, and oil and gas development to ensure that habitat quality concerns are adequately addressed;
  • review of EPA pesticide registration proposals to ensure that potential impacts to fish and wildlife are considered, and review of pesticide use on FWS lands to ensure these chemicals are properly applied and, in some cases, to recommend the use of acceptable alternatives such as integrated pest management;
  • Coordinate with Department of Defense installations and State governments on Sikes Act issues, create and participate in field-level partnership teams to develop, implement and monitor Integrated Natural Resource Management Plans (INRMPs);

    Contaminants Identification and Assessment. Our specialists conduct field studies to determine sources of pollution, to investigate pollution effects on fish and wildlife and their habitat, and to investigate fish and wildlife die-offs. Sites typically assessed include those impacted by pesticides, industrial wastes, oil and hazardous waste spills, and drain water from agricultural irrigation and mining, as well as Superfund sites and other sites contaminated at some time in the past. These specialists have also developed tools such as the Contaminants Assessment Process (CAP), which was developed in cooperation with the US Geological Survey, Biological Resources Division's Status and Trends Program (external link), to assist in evaluating contaminant threats to national wildlife refuges, as well as other Service lands. In addition, field specialists conduct contaminant surveys prior to the Service buying new lands and evaluate the health of our National Wildlife Refuges through amphibian malformation surveys .
