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.

The Access and Excel versions of the database provide information on who is doing what, and where, to manage aquatic and riparian invasive species in Niagara. The database tells what detection and control techniques organizations are using to manage these invasive species and how effective those control efforts are. By including organizational contact information, the database permits organizations to contact one another to collaborate in terms of sharing resources; prioritizing sites/invasives to manage; and finding and addressing gaps in where invasives are not being managed.

Invasive Species Control Methods

Note: Specific resources are included for biological and gastronomic control as these methods are not currently being used in the Niagara Region.

Invasive Species Control Effectiveness

Note: This site is not endorsing any specific products or control techniques. Resources are only provided for aquatic and riparian invasive species that were being controlled in the Niagara Region in 2017/2018.
