In my over Twenty years of managing invasive plants on the same trails in Westchester County I am happy to report that many of the negative issues that Ryan M. warned about are very low probability. Cutting the invasive plants at the base and repeating the process until the natives shade them out works quite well. If there are no native plants to shade then anything short of total removal of all invasive plants will not be effective. If you have a Barberry in the sun cut it at the base before a drought. Shade out Stilt grass with natives if a narrow path is permissible.
