Wetlands soak up water during heavy rain, then let it go slowly to help stop flooding.
As water moves into a wetland, it is cleaned by the plants. This cleaning protects downstream environments.
You can do many activities at wetlands like boating, fishing, swimming, bird watching, whitebaiting and hunting.
