What is an Invasive Plant?

Invasive plants are usually nonnative species that have been introduced intentionally or by accident and spread from human settings into natural areas with negative effects to our economy, environment or health. Other characteristics of invasives include:

  • Free from the plant-eaters and parasites that keep them in check in their native ranges
  • Reproduce rapidly and spread aggressively by (a) producing a large number of seeds and (b) sometimes reproducing by sprouting from their roots and stems
  • Take over natural areas and altering biological communities.

Mid-Atlantic Invasive Plants. - Over 280 species of invasive plants have been reported to be impacting natural areas in the six mid-Atlantic states (Delaware, Maryland, New Jersey, Pennsylvania, Virginia, and West Virginia). These impacts include displacing native plants and animals, reducing native species biodiversity, altering soil properties, water and light regimes, and destroying wildlife habitat.
