Bittersweet Barn

I stumbled upon this picture of a barn completely overrun by bittersweet vine. This is just one example of the kind of destruction an invasive species can have. Bittersweet, like kudzu, is a fast growing vine that is becoming a major problem in northern states. This picture was taken in Farmington, ME. Invasive species become a problem when they are transplanted into favorable conditions with little to no competition of native predators.
