The Niagara Region’s Aquatic and Riparian Invasive Species Control Database (created by Lyn A. Brown as part of a Master of Sustainability thesis at Brock University) provides a baseline for the 2017/18 state of aquatic and riparian invasive management activities in the Niagara Region of Ontario. An interactive GIS map uses the database information to show where those control efforts are occurring, and users can filter points on the map by invasive species, control type, control effectiveness, or organization.
