More than half the wetlands once found in Wisconsin are gone. They were filled in or drained to grow crops and build cities and roads. With the loss of our wetlands went the many services they provide.

Wetlands can improve water quality, reduce flood impacts, help streams flow, provide habitat, and offer many other services. But not all wetlands provide the same services to the same degree.

The Nature Conservancy and the Wisconsin Department of Natural Resources have created an online tool to help Wisconsin citizens find the best sites to restore and protect—and the most promising watersheds to work in.

  • Wetlands by Design: A Watershed Approach - a full report with overview, methods, and further guidance for protecting and restoring wetlands and the services they provide
  • Wetlands and Watersheds Explorer – a free online mapping tool
  • How to use the Explorer – an on-line demonstration
    • Introduction and how to access the Explorer
    • How to find a new site to protect or restore (minute 2:41)
    • Watershed ranks (minute 3:36)
    • Site ranks (minute 6:37)
    • Helpful features: Changing basemaps & transparency sliders (minute 9:25)
    • Wetland wildlife data (minute 11:12)
    • Helpful feature: Optimizing view with transparency sliders (minute 12:20)
    • Helpful features: Sharing and printing maps; downloading data (minute 12:54)
    • Helpful features: Measuring and drawing on-screen (minute 14:35)
    • How to evaluate a known site (minute 15:57)
    • Helpful features: Section explanations, info buttons, assessment methods (minute 19:59)

Who is the tool Designed for?
Potential Explorer Users Potential Applications
Local Governments Development of watershed plans for water quality, e.g. 9 Key Element Plans; siting of natural infrastructure projects
Land Trusts Strategic conservation planning; prioritizing projects; grant proposals; wetland education & outreach
Compensatory Mitigation Project Sponsors/Wetland Regulators Identify and analyze potential restoration sites; guide project selection; support mitigation goals and improve outcomes
County Planners/Regional Planning Commissions Aid in developing local and regional comprehensive plans; parks and open space plans; flood control and water quality improvements
Private Businesses Wetland restoration as one component of meeting regulatory requirements, e.g. water quality trading and Adaptive Management programs
Wetland Consultants Wetland restoration planning and design
Watershed Planners Watershed assessments, water quality planning
Nutrient Management Specialists Nutrient management planning
Wildlife/Other Resources Managers Prioritize projects; identify and analyze sites; wetland restoration planning and design
Agricultural Producers Nutrient management planning; habitat improvement
Lake Associations Lake management plans; shoreline protection; water quality improvement; education and outreach
Universities/University Extensions Wetland research; education and outreach; economic valuation of wetland ecosystem services

How can I use it?


Can you give me some examples?

If a community is experiencing increased flooding, then county planners might use the Explorer to look upstream in the watershed and determine where the best places are to protect and restore wetlands that will store water and help with flood control.

The Explorer can also be used to help secure funding for conservation of known sites. Land trusts seeking to protect a wetland can use the Explorer to describe the importance of the site for people and wildlife. Similarly, applicants seeking wetland mitigation funds can describe how restoration of a wetland can contribute to watershed goals.
