SVT developed a comprehensive management plan for the control of invasive plants. We are implementing various control techniques to compare their rates of success and the resources they require.
SVT established two demonstration plots in the 100-foot wetland buffer zone of the red pine plantation (Management Unit 1). In one plot, we are excavating the roots and attempting to completely remove the bittersweet. In the second plot, we are cutting all bittersweet vines two to three times per year.
Throughout the growing season, SVT staff, contractors, and volunteers excavate Asian bittersweet roots in the 50-foot buffer zone of the wetlands in the Residential Buffer of the red pine stand and the European tamarack stand (Management Unit 2).
SVT staff laid down cardboard and wood chips over an area in the southeast corner of the property in an attempt to smother all vegetation, including any bittersweet that is resprouting. The goal is to kill existing vegetation and eventually to put down a native seed mix.
If you would like to volunteer, please contact Jane Maloney, Land Steward, at [email protected].
SVT hired Bay State Forestry Service to conduct herbicide applications to Asian bittersweet in Management Units 1, 2, and 5. This has included cut-stump and foliar applications. Backpacks with handheld sprayers have been used to carefully target only the bittersweet and some other invasive shrubs. This treatment will be expanded to Units 3 and 4 beginning in late Fall 2022.
