The purpose of this particular field guide is to give a scientific synthesis of what is known about the behavior of such species in managed, disturbed, and pristine forested systems in addition to key information for accurate identification. Such information will be helpful when prioritizing research questions and choosing the best control strategies. Control methods for each species are not provided. The most successful control methods are most often site-specific; over-generalizing control methods might lead to poor management and frustrating outcomes. This is not to say that the information that is available should not be used; this guide just could not do it justice and still achieve its primary goals. The USDA Forest Service recognizes that the threat of invasive plant species to public and private forests is serious and that successful progress in prevention, control, research, and restoration from the negative impacts of such invasions is only possible using a concerted and organized effort. Thus, the Forest Service-Eastern Region (Region 9), the Northeastern Area (NA) State and Private Forestry, and the Northeastern Research Station have joined forces to put this guide together for the public. 收起
