Vine with grape-like leaves; behaves like the bittersweet vine in that it climbs aggressively into trees and strangles them. To distinguish from a native grape, look for the multi-colored berries in Sept-Oct, the dark brown bark, and the leaves which are variable but at least some will be deeply lobed (unlike natives).
Climbs, strangles, crowds out native species.
Much like bittersweet – hand pull small vines, dig larger ones, cut ones that can’t be dug (cut at base and also at eye level). Once cut, it is not necessary to pull the vine down from the tree; when it has died it will easily be pulled down. Resprouts from cut stumps will occur if not chemically treated.
Dispose of any berries in bags and incinerate with trash.
