Upper Mississippi River Wetland of International Importance
Wetlands are marshy areas where there is much moisture in the soil.

Wetlands are considered the most biologically diverse of all ecosystems.

Wetlands hold and slowly release flood water and snow melt, recharge groundwater, act as filters to cleanse water impurities, and recycle nutrients. A wetland is an area of land whose soil is saturated with moisture either permanently or seasonally.
