Why are invasive species harmful?
- Invasive plants (weeds, exotic plants, non-native plants) have significant environmental, social, and economic impacts on natural areas, parks, and open spaces.
- Invasive species are a leading threat to the native species of the United States, second only to habitat destruction.
- Invasive plants consume approximately three million acres of land each year.
- Some invasive plants are harmful to human and animal health.
- Many invasive plants are allelopathic (they release chemicals into the soil that inhibit the growth of other plants).
- Invasive plants can cause erosion, alter water ways, limit plant and animal diversity and lower property values.
