Bulletin #62: Help Fight Invasive Trees
The following links will take you into the world of invasive trees and the organizations doing their best to fight back. However, be sure to also use your search engine to determine what species are listed as invasive in your state. An initial link that may help is maintained by the U.S. Department of Agriculture. The lists you will find may be a little overwhelming because they include noxious weeds as well as trees. Your state forester’s office can help provide more clarification about the specific trees that are troublesome locally.
