Along with the Northumberland Land Trust, Lone Pine Marsh Sanctuary hosted an event at the Cobourg Community Centre on February 18 on the Identification and Management of Invasive Plant Species in Northumberland County.
The event was very well attended and we learned a lot from the speakers, Ken Towle and Bill Newall.
Ken gave us background on how invasive species arrive and their invasive qualities. The stages of invasion include Introduction, Naturalization, Facilitation, Spread, Interaction, and Stabilization. Invasive species that are abundant in Northumberland county are dog-strangling vine (Cynanchum sp.), garlic mustard (Alliara petiolata), buckthorn (Rhamnus sp.), Phragmites australis, Elaeagnus umbellata, scotch pine (Pinus sylvestris). Spotted Knapweed, Japanese knotweed, water soldier, giant hogweed, Himilayan balsam, and Norway maple are also found in our region. Bill Newell discussed chemical controls for invasive plants and his experience with controlling invasive plants in the region.
