A land area covered with water during all or part of a year is referred to as a wetland. Wetlands include swamps, marshes, and bogs, and they play a crucial role in ecosystems by filtering water, providing habitat for wildlife, and serving as buffers against flooding. These areas can be freshwater, saltwater, or brackish and are characterized by unique vegetation adapted to saturated conditions. Wetlands are vital for biodiversity and environmental health.
