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.
