Upstate New York. "Invasive" vines are smothering trees and shrubs along parkways and roads. The only way to stop them of course is to poison them, but that kills everything else along with them. There have been initiatives to get armies of folks out there pulling them up, which of course spreads them by the bits that get left behind - these initiatives to my knowledge have never worked. Maybe the vines are trying to tell us something about parkways and roads. Maybe they are giving a protective coating to the trees and shrubs already there, a kind of seed saving enterprise so that long after the roads are gone, the stuff that used to grow there happily can come back. Vines are interesting though, so robust, grow so quickly. They are here for a reason.
