Marsh vegetation is a type of plant life that grows in wetlands, such as marshes, swamps, and bogs. Common marsh vegetation includes reeds, which are tall, grass-like plants with hollow stems. Reeds are often used for weaving and construction, and they provide food and shelter for many species of birds and animals. Marsh vegetation also includes cattails, sedges, and rushes, which are all types of grass-like plants. These plants help to stabilize the soil and provide habitat for wildlife.
