What is marsh known for?
Both saltwater and freshwater tidal marshes serve many important functions: They buffer stormy seas, slow shoreline erosion, offer shelter and nesting sites for migratory water birds, and absorb excess nutrients that would lower oxygen levels in the sea and harm wildlife.
How deep is a marsh?
The water in freshwater marshes is usually one to six feet deep and is rich in minerals. Water flows into marshes from rain or from a water source like creeks, streams, or rivers. Low-growing plants like grasses and sedges are common in freshwater marshes. Bulrushes and cattails are often found at the edges of a marsh.
Does the marsh smell?
The marshy soil is comprised of mud and peat, which is made of decaying plant matter. This decomposing organic matter combined with salt water flooding can make the soil hypoxic, meaning its oxygen levels are low. This results in its pungent and distinctive “rotten egg” smell.
What is marsh habitat?
Marshes are low-lying wetlands covered under shallow waters for long periods of time. They are usually formed in lowlands and plains near lakes and creeks, river banks or river mouths where water drainage is poor. They consist of grass-like vegetations which is able to grow in a waterlogged soil.
What is the world’s largest marsh?
At more than 42 million acres, the Pantanal is the largest tropical wetland and one of the most pristine in the world. It sprawls across three South American countries—Bolivia, Brazil and Paraguay—and supports millions of people there, as well as communities in the lower Rio de la Plata Basin.
