Wetlands are defined as geographical areas where water covers or overly saturates the soil during the majority of growing seasons (CZM). They vary based on their appearances and locations which are greatly influenced by regional and soil divergence such as topography, climate, water chemistry, vegetation as well as human degradation (CZM).
Wetlands are identified based on three major attributes: the constant availability of water (hydrology), the presence of specially adapted plants (hydrophytes) and the developmental condition of the soil (hydric) (CZM). Wetlands, which consists of a variety of natural

Most cities in Louisiana such as New Orleans sit below sea level.

These large inflows of muds nurtured or sustained the Mississippi delta, thus producing 5 million acres of South Louisiana prior to the twentieth century (Tibbets, 2006). The muddy river with along with the Mississippi River generated six distinct “delta lobes” in which the coastline of South Louisiana was formed (Tibbets, 2006). These wetlands became a reservation for many fish, birds, and various plants species endanger of extinction as well as serve as a buffer from giant storms by acting as a holding ground for excess water.
