TRANSFER LOSS OF WETLAND PERFORMANCE IN NEPONSET RIVER An Interpretation of social and environmental design Greater Boston Historic map since 1800 traced the ecological foot print of salt marsh loss as much as 80% of its performance. A dramatic decreasing in capacity to mitigate salt water over the last 200 years. Much of Boston’s marshes and surrounding mud and sand flats were dredged or filled in the early 1800s to increase Boston’s acreage. High and rapidly growing population and suburban sprawl resulted in conversion of substantial areas of natural land to urban and industrial use. Recent rise in duration and frequency of flooding events increasing precipitation, hydraulic alterations (by damming, ditching, or filling) and development of urban or agriculture land are all common cause of wetland conversion. These cannot be restored easily or trend naturally. Along with the salt marsh land, disappeared natural and rich habitat and wild life ecosystems that were tied to those wetlands and depend on their surviving. Maltreatment of Greater Boston salt marshes continued until the 1970’s when the U.S general public and federal government began to recognize the significant ecological services that salt marshes provide as a marine nurseries, shorebird habitat, and coastal stabilizers and flood control measure. Neponset river watershed is one of seven watershed systems in the great Boston area, it is wide spread water systems that includes ponds lakes, river streams and creeks with a richness of nature, ecosystem and wild. Like other water shed in this area, this watershed had lost more than 80 percent of its marsh land.
