Salt Marshes

By: Johnny Mckinnes, Alex Brookins, & Olivia Kelly


Salt Marshes; are coastal wetlands that are flooded and drained by salt water brought in by the tides. They are marshy because the soil may be composed of deep mud and peat. Peat is made of decomposing plant matter that is often several feet thick. Peat is waterlogged, root-filled, and very spongy.

Plant survival

In order for plants to live in salt marshes they must be able to cope with salt water flooding, dryness during low tides, waves, and varying salinity and temperatures. Many salt marsh plants have glands on their leaves which help them to get ridge of excessive amounts of salt, A good example would be Grasswort.

Salt Marsh Ecosystem

Importance of salt marshes

Salt marshes are among the most productive ecosystems on earth. The plants in salt marshes survive on the minerals brought in but the tides, tides work as a two way street the bring in nurtrinets in for the plants and bring nurtrinets out for the fish. Over time, salt marshes accumulate organic material, forming into a dense layer called peat. Salt Marshes also slow the velocity of waves before they reach land and mitigate storm surges.

Threats to ecosystem

Are humans and their machines which release enormous amounts of pollution to the air, water, and soil. Also exotic plants and animals introduced by humans can change community composition and disrupt food webs and ecological functions.
