GRADE CHANGE -- SOFTEN THE EDGE

A salt marsh is an environment in the upper coastal intertidal zone between land and salty or brackish water, is dominated by dense stands of halophytic (salt-tolerant) plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the exporting of nutrients to coastal waters. They also provide support to terrestrial animals such as migrating birds as well as providing coastal protection.
ECO - ISLANDS
A wetland is an area of land whose soil is saturated with moisture either permanently or seasonally. Such areas may also be covered partially or completely by shallow pools of water. Wetlands include swamps, marshes, and bogs.
Wetlands are considered the most biologically diverse of all ecosystems. Plant life found in wetlands includes mangrove, water lilies, cattails, sedges, tamarack, black spruce, cypress, gum, and many others. Animal life includes many different amphibians, reptiles, birds, insects, and mammals.
THE WETLAND
THE TIDAL SALT MARSH
Currently the edges of Harlem River are mostly created by landfill. The riprians are straight with mostly impervious pavements, which reduce the bio-diversity and speed up the water flow.
