Aquatic Ecosystem Restoration Program

Program Information

Popular name

AERP

Program Number

15.580

Program objective

The objective of the Aquatic Ecosystem Restoration Program is to work cooperatively with states, Tribes, and other entities as they study, design and construct aquatic ecosystem restoration projects that are collaboratively developed, have widespread regional benefits, and result in the improvement of the health of fisheries, wildlife, and aquatic habitat through restoration and improved fish passage. As used here, “aquatic ecosystem” refers to freshwater and brackish water habitats such as lakes, ponds, rivers, streams, wetlands, swamps, and estuaries and the adjacent floodplains, riparian corridors, deltas, and shallow aquifers that interact with surface water.
