Please support this Plant listing. I have personally spent hundreds of hours cutting these plants from County and National Parks in Northern Virginia. There are not enough resources to control these aggressive plants. They are killing our native trees from small saplings to large mature trees and you are often left with only Invasive plants left.  Some invasives kill trees by the acre.  We must do all we can to limit their spread.  This listing is a step in the right direction.  Please expand the list as noted in other comments and include English Ivy especially, it is out of control in many natural areas in Northern VA and around the state. Thanks for your efforts.
