Controlling Invasive Plant Species: Targeted Herbicide Use in London’s ESAs

The UTRCA and the City of London are working to protect London’s Environmentally Significant Areas (ESAs) from invasive plant species that are threatening their unique ecology. These non-native invasive species include Japanese Knotweed, Giant Hogweed, Glossy and European Buckthorn, Phragmites and Dog Strangling Vine.

Many approaches to controlling invasive plant species have been tried over the past decade. The most effective technique for controlling these invasive species is herbicide injection and targeted, specific herbicide spray. These herbicides are approved for use by Health Canada, and carefully applied by licensed applicators on staff with the UTRCA who follow the Best Management Practices approved by the Ontario Invasive Plant Council and the Ontario Ministry of Natural Resources and Forestry.
