Aquatic Ecosystem Restoration

The Corps Aquatic Ecosystem Restoration program focuses on restoring degraded ecosystem processes to a more natural condition. Projects restore aquatic resources such as wetlands, rivers and estuaries. The primary focus is on large hydrologically complex projects. Non-Federal partners share the cost and maintain projects.


What This Rating Means

Results Not Demonstrated

A rating of Results Not Demonstrated (RND) indicates that a program has not been able to develop acceptable performance goals or collect data to determine whether it is performing.
  • The Corps has revised its measures and has baselines for two annual and one efficiency measure. Targets have been developed for the revised measures, except for the new efficiency measure. The number of acres restored annually, the percentage of the four year total that is nationally significant, and the cost per acre to restore nationally significant acres will be among the metrics measured.
  • Individual projects receive extensive review but the program as a whole has not been subject to regular independent evaluation. Such evaluation may contribute to identification of enhanced methods for performing comparative analysis of projects with dissimilar ecological outputs, refinement of the definition of nationally significant, and improved or alternative performance metrics.
  • The program focuses on restoring nationally and regionally significant ecosystems throughout the United States in partnership with local entities. The Corps program is relatively unique in its focus on larger projects requiring modification of hydrology and geomorphology.

Improvement Plan

About Improvement Plans

We are taking the following actions to improve the performance of the program:

  • Increasing focus on project effectiveness through environmental benefit assessment research. Increased project effectiveness will contribute to increased program effectiveness.
  • Database development will provide new information about the projects and habitats restored. This will aid in answering questions about outputs and may assist with evaluation of program performance.
  • Identifying the most effective means to obtain independent program evaluation. Specific criteria will be developed to be considered in a program review by building on previous and ongoing reviews.
