ABSTRACT
The purpose of the study was to inventory and evaluate non-natural restrictions to tidal flow in the vegetated tidal marshes (salt marshes) of New Hampshire. The study focused on restrictions to tidal flow because the daily flux of seawater is the life blood of a salt marsh. When impediments to tidal flow are created, profound changes take place; marshes may degrade to the point where they no longer provide their characteristic suite of functions and values, such as wildlife habitat or visual/aesthetic quality. If restrictions are severe enough, marshes may be replaced by brackish or freshwater wetlands, usually of lower ecological value. The study found that there are numerous locations in New Hampshire where salt marshes have been degraded, at least in part, due to restrictions to tidal flow. Estimated restoration costs range from less than $100 per acre to over $25,000 per acre. Before any restoration effort is undertaken, other factors not addressed in detail in this report should be considered, including the impacts on flooding from any modifications to the restrictions
