Explore Wisconsin’s wetlands
The best way you can get to know wetlands is by getting your boots wet while exploring them. Whether you like strolling on boardwalks or getting chest-deep in your waders, Wisconsin’s wetlands are ready for your discovery.
How can I tell if I’m standing in a wetland?
Wetlands are found all across Wisconsin and come in many different sizes and types. Some wetlands, like large open marshes, are obvious. Some wetlands, like forested ephemeral ponds, may be harder to spot. Here are a few tips for recognizing a wetland:
- The presence of water-loving plants: Look for plants that love wet soil or water, like cattails, sedges, marsh marigold, and more
- Wetland soil: The soil in a wetland often appears darker than upland soils. The soils may also show rust spots or be grayish or bluish gray. While many wetlands have muck or peat soils, wetland soils can also be comprised of silt, clay, and sand.
- Hydrology indicators: If you are in a low-lying area with standing water or soggy soil, you’re likely in a wetland.
- Clues from surrounding trees: Shallow root systems and water mark stains on tree trunks can mean you are in a wetland, even if the ground is currently dry.

Wetlands of International Importance
Wisconsin has many beautiful, valuable wetlands. To celebrate these wetlands and ensure their long-term protection, we’ve worked to nominate some of Wisconsin’s most special wetlands for designation as Wetlands of International Importance. This designation is awarded by the Ramsar Convention on Wetlands, an international organization that encourages wetland protection. We’re proud to participate in the nominations of many of Wisconsin’s special wetlands. Use the links below to read Ramsar’s profile on each site.
