Michigan Tech Advances Vernal Pool Mapping
A multi-year research project led by the Michigan Tech Research Institute and Michigan Technological University, in partnership with the National Park Service, has successfully mapped and classified vernal pools across national parks in the Great Lakes region. Using a combination of field surveys and advanced remote sensing methods—including LiDAR, optical imagery, and radar—the team identified and verified hundreds of potential vernal pools from 2019 to 2024. Fieldwork confirmed dozens of vernal pools in parks such as Sleeping Bear Dunes, Pictured Rocks, Apostle Islands, Isle Royale, Voyageurs, and Indiana Dunes, with many pools supporting key indicator species like wood frogs, salamanders, and fairy shrimp1.
The research team developed a new classification system for vernal pools, highlighting the importance of canopy cover type in supporting species diversity. Their mapping approach, refined over several years, now enables accurate detection of these dynamic wetlands even in challenging forested landscapes.
The project’s results have been shared at scientific conferences and published in peer-reviewed journals, providing valuable data and tools for park managers and conservationists to monitor and protect these critical habitats in the face of environmental change.
Congrats to the team for all the hard work that went into advancing vernal pool mapping!!
