List of National Natural Landmarks in Wisconsin facts for kids

Did you know that Wisconsin has some really special natural places? These places are called National Natural Landmarks (NNLs). They are like nature's treasures! There are 18 of these landmarks in Wisconsin. They are part of almost 600 such places across the United States.
These landmarks protect important natural areas. They can be unique landforms, special forests, or homes for rare plants and animals. Some are sand dunes, swamps, or very old forests. Many of these spots help protect plants and animals that are hard to find elsewhere. The Driftless Area in southwest Wisconsin is especially famous for its rare species. The Baraboo Range is a great example.
These special places are owned by different groups. Some are owned by individuals or Native American tribes. Others are managed by state or federal agencies. These landmarks were chosen between 1967 and 1987. They range in size from small (about 44 acres) to very large (over 53,000 acres).

What are National Natural Landmarks?
The National Natural Landmarks Program helps protect America's natural heritage. The National Park Service runs this program. This is a part of the Department of the Interior. They decide which places are important enough to be NNLs.
First, they check if a place meets certain rules. Then, they tell the owners about the idea. The Secretary of the Interior makes the final decision. Both public and private lands can become NNLs. Owners can say no if they don't want their land to be a landmark. Being an NNL helps protect these places. It can offer tax benefits or grants to help care for the land.
