How Invasive Plants are Spread


Spread of Marsh Thistle 1981-2002

Because invasive plants are spread easily, it is critical that the public become aware of the numerous ways that these plants are spread.

Invasive plants can spread by means of:

  • Seeds carried by livestock and wildlife
  • From land clearing and logging
  • By land and water-based recreational activities
  • Horticultural industry selling non-native species
  • From excessive grazing
  • Along transportation corridors
