Title: Smarty Plants Exotic Species
Answered by: Jil M. Swearingen, National Park Service
QUESTION:
What Makes an Exotic Species Invasive? (When is a Guest a Pest?)ANSWER:
Many non-native species exist in apparent harmony in environments where they were introduced. For example, a relatively small number of exotic plants (e.g., corn, wheat, rice, oats) form the basis of our agricultural industry and pose little to no known threat to our natural ecosystems. The most important aspect of an alien plant is how it responds to a new environment. An invasive species is one that displays rapid growth and spread, establishes over large areas, and persists. Invasiveness is characterized by robust vegetative growth, high reproductive rate, abundant seed production, high seed germination rate, and longevity. Some native plants exhibit invasive tendencies in certain situations.More Invasive Plants Questions
