Early Detection and Distribution Mapping System (EDDMapS) Ontario is a web-based mapping system for documenting invasive species distribution. This existing provincial system is a fast and easy way to map invasive species without requiring any GIS or technical computer experience. Promoting the use of EDDMapS to the public not only helps homeowners become more engaged, but also educates them about invasive species recognition. Using a common reporting tool allows the distribution information to be kept in one central database. Invasive species tracked by EDDMapS can be found at https://www.eddmaps.org/ontario/Species / .
