How can the land that built the land in south louisiana could be used to restore wetlands
Answers
In many Louisiana swamps, Cypress (Taxodium spp.) and Tupelo Gum (Nyssa aquatic) trees are key species. Marshes are areas that frequently or continually hold water and have non-woody, soft, green vegetation, including grasses and sedges. Marshes are classified according to the salt content of their water (called “salinity”) and the resulting plant and animal life that grows and thrives in that environment.
Fresh marshes contain fresh water and have the highest diversity of life. Intermediate marshes have a salt content of 0–5 ppt., brackish marshes, 5–15 ppt. and salt marshes have greater than 15ppt. of salinity. The plant species richness (number of species present) greatly decreases as the salt content increases. Few species can survive in the harsh environment of salt water marshes that are inundated daily with salt water tides.
Subsidence is one of the largest causes of coastal land loss, but cannot even begin to rival the human impact in either the amount of coastal land destroyed or the rate of its destruction. Human disturbance has had a massive impact on the balance of wetland growth and decline
