Marsh ecosystems are wetland areas characterized by the presence of herbaceous plants, such as grasses and sedges, that thrive in saturated soil. These ecosystems play a crucial role in water filtration, flood control, and providing habitat for various species, including birds, amphibians, and insects. Marshes can be found in both freshwater and saltwater environments, contributing to biodiversity and ecological balance. In addition to their ecological importance, marshes serve as vital carbon sinks, helping to mitigate climate change by storing carbon dioxide. They also support recreational activities and can enhance local economies through tourism and fishing. Protecting marsh ecosystems is essential for maintaining their benefits to the environment and human communities.
