What does marsh environment mean?

A marsh is a wetland ecosystem that is dominated by grasses, reeds, or other herbaceous plants. Marshes are often found in low-lying areas that are poorly drained, such as along rivers, lakes, or coasts. They may also occur in areas that are periodically flooded, such as rice paddies.

Marshes provide a number of important functions, including:

* Filtering water and removing pollutants

* Providing habitat for fish, birds, and other wildlife

* Preventing erosion

* Storing carbon dioxide

Marsh ecosystems are threatened by a number of human activities, including:

* Drainage for agriculture or development

* Pollution from fertilizers and pesticides

* Invasive species

The loss of marsh ecosystems can have a negative impact on water quality, wildlife habitat, and climate change.
