A former cranberry bog in central Wisconsin has been transformed into a thriving wetland ecosystem, providing a model for how degraded agricultural lands can be restored to their natural state. The project, led by a team of scientists and conservationists, has not only revived the local wetland but also helped inform new approaches to large-scale wetland restoration efforts across the Midwest.

Why it matters

Wetlands are critical natural habitats that provide flood control, water filtration, and biodiversity. However, over 50% of the world's wetlands have been lost to development and agriculture. This project demonstrates how innovative conservation techniques can breathe new life into degraded lands, restoring vital ecological functions and setting an example for future wetland restoration efforts.

The details

The 160-acre cranberry bog, located just outside of Madison, Wisconsin, had been in agricultural use for decades before being acquired by a local conservation group. Using a combination of controlled flooding, native plant reintroduction, and invasive species management, the team was able to transform the barren, monoculture landscape back into a thriving wetland ecosystem teeming with diverse plant and animal life.

  • The conservation group acquired the former cranberry bog in 2018.
  • Restoration efforts began in 2019 and were completed in 2022.
  • The revitalized wetland was opened to the public in the summer of 2023.

What they’re saying

“This project has shown us that with the right approach, we can breathe new life into even the most degraded lands and create vibrant, biodiverse habitats that benefit both wildlife and the surrounding community.”

— Dr. Emily Larson, Lead Ecologist

“Seeing this former cranberry bog transform into such a lush, thriving wetland has been truly inspiring. It's a testament to what can be achieved when conservation groups, scientists, and the community work together.”

— John Wilkins, Executive Director, Dane County Conservation Group

What’s next

The Dane County Conservation Group plans to use the lessons learned from this project to guide future wetland restoration efforts in the region, with the goal of expanding the network of healthy, biodiverse wetlands throughout southern Wisconsin.

The takeaway

This innovative wetland restoration project has not only revived a critical natural habitat, but also demonstrated the immense potential for transforming degraded agricultural lands into thriving ecosystems. The success of this effort provides a roadmap for conservation groups and policymakers seeking to address the global decline of wetlands and the vital ecological services they provide.
