Flood control
Wetlands soak up water during heavy rain, then let it go slowly to help stop flooding.
Water quality
As water moves into a wetland, it is cleaned by the plants. This cleaning protects downstream environments.
Sediment removal
Wetlands stop sediment flowing into rivers, lakes and harbours where it can smother the bottom with silt. Silt damages habitats for plants, invertebrates and fish.
Recreation
You can do many activities at wetlands like boating, fishing, swimming, bird watching, whitebaiting and hunting.
Tourism and education
People like to visit wetlands. There are many different plants and animals to see and learn about.
Special habitats
Many of New Zealand’s endangered plants and animals need wetlands to survive.
