    • Wild Spotter is a nationwide effort to complete a comprehensive map and survey of prioritized invasive through on-the-ground activities accomplished by citizen science volunteers. Wild Spotter is a tool that allows the general public to report invasive species in their favorite places. Unlike, EDDMapS it is focused locally and focused on the non-traditional invasive species audiences. Widespread adoption and use of Wild Spotter is key to protecting our public lands.  Wild Spotter is part of EDDMapS, data is part of the EDDMapS database, and it uses the existing EDDMapS review and verification system.
