The term “invasive” is used to describe a plant which grows rapidly, spreads aggressively, and displaces other native plants. They are non-native to the area but have naturalized and negatively affect the ecosystem they inhabit. Invasive plants degrade native environments by causing a decline in native plant species diversity. They degrade wildlife habitats for native insects, birds, and other wildlife and threaten rare species. In addition, invasive plants have been shown to inhibit forest regeneration success and slow or halt natural succession. Once well established, invasive plants require large amounts of time, labor, and money to control or eradicate.

Penn State Extension has published these detailed resources to help with identification and control of common invasive forest plants. Each four-page fact sheet provides in-depth practical information to help landowners and natural resource professionals identify and treat invasive plants commonly found in fields, forests, and other natural areas. The fact sheets provide full-color images and descriptions to assist with identification, as well as information on native look-alikes, dispersal, site, and control, including a management calendar and treatment and timing table.
