Terrestrial/Riparian Invasive Species

Terrestrial and riparian invasive plants are non-native species that are generally free of the natural predators that help keep them in check in their native country of origin. Without natural predators and/ or diseases to control them, and with their aggressive growth and abundant seed production, these plants spread rapidly and extensively through our native ecosystems. 

What are the impacts of terrestrial and riparian invasive species?

  • Degrade wildlife habitat
  • Reduce biodiversity and cause the extinction of endangered species
  • Reduce crop quality and yield
  • Reduce forage availability for grazing animals
  • Increase wildfire hazard
  • Interfere with regeneration of forests
  • Increase soil erosion Impact recreational activities

You can make a difference!!!

  • Prevent infesting new areas by not planting invasive plants or their seeds
