Wetlands

Wetlands benefit people and nature

Wetlands are nurseries for fish and wildlife, purifiers for lakes, rivers and groundwater, and storage for floodwaters. They’re also playgrounds for birders, hikers, hunters and paddlers, and a storehouse for carbon, one of the greenhouse gases fueling climate change. Please help protect, restore and explore Wisconsin’s wetland wonders.
