National Resource Damage Assessment and Restoration (NRDAR)
Fish, wildlife, and other natural resources can be injured when oil or hazardous substances spill or are released into the environment. We work with others on Natural Resource Damage Assessment and Restoration -- collecting data, estimating injuries, identifying restoration opportunities, and restoring natural resources and habitats. In partnerships with NOAA, North Carolina Department of Environmental Quality, and Virginia Department of Environmental Quality, we are making progress on restoration at three sites:
The U.S. Fish and Wildlife Service works with stakeholders to coordinate sediment evaluation at dams proposed for removal in NC and SC -- providing data, reports, and guidance. Technical assistance includes syntheses of existing information, field reconnaissance, coordination with dam owners and regulators, and (when necessary) sediment collection and testing to determine sediment quality.
The U.S. Fish and Wildlife Service has partnered with the U.S. Geological Survey to establish two automated water-quality monitoring stations at Lake Mattamuskeet to better understand the lake’s ecology. Managers are concerned that submerged macrophyte populations have declined on the west side of the lake and we are helping determine the extent to which the decline may be due to poor water quality.
The Service’s Environmental Contaminants Program collects and interprets data to help the public, regulators, and other decision makers. With the removal of Milburnie Dam under consideration, we coordinated an investigation of sediment pollution as technical assistance to interested stakeholders. Our final report demonstrates that concentrations of heavy metals and hydrocarbons in sediments upstream of the dam are less than levels of concern. We also documented that the highest sediment pollutant concentrations were typically from downstream of the dam.
Responding to Climate Change: Carbon Sequestration Benefits of Drained Peatland Restoration (pdf 476Kb). U.S. Fish and Wildlife Service Environmental Contaminants ecologists reduce pollution through prevention and restoration. The agency is being challenged to address climate change, important drivers of which are pollutants such as carbon dioxide and nitrous oxide. Restoring drained peatlands is a quantifiable approach to sequestering these pollutants, an approach that contaminants ecologists have facilitated in eastern North Carolina.
