About Retrospective Evaluation
Background
Despite substantial investments in aquatic ecosystem restoration nationally, there is little or no quantitative monitoring of ecological response, and little or no basis upon which to assess project and program success (Bernhardt et al. 2005; Ruiz-Jaen and Aide 2005). Furthermore, few national databases have been developed for ecosystem restoration projects (Jenkinson, 2006; Palmer et al. 2007; Roni, 2008). Monitoring and assessment efforts within the US Army Corps of Engineers (USACE or Corps) largely reflect this pattern (Fischenich, 2011). Better data and information are needed by the Corps and others to ensure that restoration investments maximize environmental benefits to the Nation. This retrospective analysis was undertaken to 1) characterize the nature, scope and distribution of ecosystem restoration projects implemented by the Corps, 2) evaluate project success and the factors contributing to that success, and 3) identify lessons learned and innovative practices.
