It is too late for Early Detection, Rapid Response (EDRR) in Southeastern Pennsylvania for the mile-a-minute vine (Polygonum perfoliatum). The horse is already out of the barn. When you see it along the roadside, you probably no longer register surprise. It isn't everywhere, but it's getting pretty close.
But it has just started to invade the lower Hudson Valley in New York, and I travelled there to be a speaker at a conference convened to develop a strategy for pushing back the invasion. My role in part was to frighten attendees about the risks of not controlling this plant, and to give an "on-the-ground" perspective of someone who has managed mile-a-minute for over a decade. I related the pattern of invasion we have observed, and despite our thorough efforts, how the populations have continued to expand. (Unless everyone in the region is controlling it, then it is difficult for anyone to control it.)
State or region-wide strategies are needed to manage most invasive species, and I am very pleased to see New York engaged in this kind of effort, particularly so early in the invasion.
