Watershed Approach Handbook: Improving Outcomes and Increasing Benefits Associated with Wetland and Stream Restoration Projects advances the use of a watershed approach in the selection, design and siting of wetland and stream restoration and protection projects, including projects required by compensatory mitigation. The handbook, jointly developed by ELI and The Nature Conservancy, demonstrates how using a watershed approach can help ensure that these projects also contribute to goals of improved water quality, increased flood mitigation, improved quality and quantity of habitat, and increases in other services and benefits. It provides an overall framework for the spectrum of watershed approaches, examples of specific types of these approaches, examples of types of analyses that may be useful for using one, and a list of national data sources that might inform all of the above. It also provides some guidance and lessons learned about considerations when developing wetland and stream protection and restoration projects.
