What are invasive plants?

Plants that are capable of causing economic and environmental damage, and/or harm to human health are often termed invasive. Invasive plants are characterized by fast growth rates, excessive fruit production, and efficient seed dispersal and germination. Exotic plants often escape the natural enemies, predators, and pathogens that keep them in check in their native range. This lack of natural control contributes to their ability to spread and become weedy.

Some invasive plants were intentionally introduced for erosion control, food, forage, wildlife habitat, aesthetics, and medicinal use. Others arrived accidentally through international trade routes. Some invasive plants also escape to natural areas from home gardens.
