Cape Cod Restored Marshes

The challenge of wetland persistence is complicated by widespread management and alteration of wetland hydrology, and built infrastructure within migration corridors. Human development and utilization of coastal landscapes in the U.S. during the past several centuries has resulted in loss of approximately half of tidal wetland area, largely due to 1) restriction of tidal flows, through intentional diking and drainage or impoundment, 2) construction of levees, or road and railroad construction leading to varying degrees of impoundment, and 3) development on drained/filled wetlands with critical portions of our developed and urbanized coasts are built on drained and filled former tidal wetland. We have estimated that ~40% of remaining [...]
