The Wetland Conservation Act
In 1991, the Wetland Conservation Act was passed in Minnesota. The goal of the Act was to protect Minnesota's valuable wetlands through no net loss of the states remaining natural wetlands. The Act designates that before any activity regarding draining, filling, or excavating occurs in a wetland an attempt must be made to first avoid the impact to the wetland, and if the impact can not be avoided, the impact must be minimized, and if the impact can not be minimized then the wetland must be replaced with one of equal public value.
