A document was developed on lessons learned from marsh restoration projects within NPS and Ducks Unlimited Canada related to constructed wetlands.

This report provided information on constructing new wetland systems in a way that management interventions can be kept to a minimum over the lifespan of the project. For constructed and restored wetlands, Minimum Ecological Management (MEM) calls for taking those actions (both early-on and after construction) that best provide for the long-term sustainability of natural hydrological cycles appropriate for the intended wetland type and characteristic of the region in which the wetland project is located. Taking the appropriate actions at the right time greatly reduces the need to intervene over the lifetime of a wetland project.
