Wetlands are some of the most biologically productive natural ecosystems in the world, and are comparable in their productivity and diversity of species, to tropical rain forests and coral reefs. Abundant vegetation and shallow water provide diverse habitats for fish and wildlife. Aquatic plant life flourishes in the nutrient-rich environment, and energy converted by the plants, is passed up the food chain to fish, waterfowl, and other wildlife and to people as well. In this way, the wetlands are supporting valuable commercial fish and shellfish industries.
