The Wisconsin Idea in Action

Great Lakes Early Detection Network

The Great Lakes Early Detection Network (www.gledn.org) is a website for reporting invasive plant locations. The website is free for anyone to use. Users can submit invasive species locations which are then verified by a network of experts we have developed for the entire Great Lakes Region. This site makes it easy for citizens to join in the efforts to control invasive species. Invasive species have a huge negative impact on agriculture, forestry, trade, and recreation across the United States. By collecting information from citizens those people who manage invasive species have a better idea of where and when new invasives enter our state.

Outcomes

GLEDN has been able to accumulate over 750,000 invasive plant locations throughout the Midwestern United States and communicate new alerts to land managers. It is currently the most comprehensive source for invasive plant location data in the region. This information is critical to track invasive species movement, predict spread, and regulate species of concern.
