Wetland ecosystems are areas where water covers the soil, either permanently or seasonally. They include marshes, swamps, and bogs, and are characterized by unique plant and animal life adapted to saturated conditions. Wetlands play a crucial role in filtering pollutants, storing floodwaters, and providing habitat for diverse species. These ecosystems support a variety of wildlife, including birds, fish, and amphibians. They also serve as important breeding grounds for many species. Additionally, wetlands help maintain water quality and regulate local climates, making them vital for both environmental health and human communities.
