Invasive Exotic Plants
Invasion of nonnative plants into rural and urban forested landscapes can have devastating effects on natural ecosystems and biodiversity. These plants displace native species and upset the natural associations between plants and animals. Invasive exotic plants occur as trees, shrubs, vines, grasses, ferns and forbs. Many of the invasive exotic plants within the Arboretum have spread from farmstead homes previously found throughout the area.
The Arboretum has taken active measures to eliminate or control the spread of nonnative invasive plants such as those listed below and to promote the use of non-invasive alternative plants.
All images are from the publication "Invasive Plants of the Eastern United States CD-ROM." The photographer is listed with the individual images. A complete list of plants can be viewed at www.invasive.com
