Scotch Broom ChallengeScotch_Broom_Picture_from_Brochure_14.png

Local groups and agencies are teaming up to encourage local landowners, businesses, organizations and agencies, basically everybody that is affected by the invasion of Scotch broom to start physically removing the plant. We hope to help educate and get people motivated in the region to combat this invasive weed.

If you would like to suggest or host a site for an upcoming challenge or would like to participate in a Scotch Broom Challenge please contact contact us.

What’s the fuss about?

Scotch broom (Cytisus scoparius) is a highly aggressive non-native invasive weed species. It was introduced to the United States as an ornamental and as packing material for cases of whiskey and beer from the British Isles, central and southern Europe. It is now considered a pest plant by many eastern and western states.

Why is this plant considered a pest?

  • Scotch broom is highly flammable
  • Displaces native and beneficial vegetation.
  • Costly in areas where forest production is impeded by its growth
  • Forms dense stands which impede movement of wildlife and livestock and degrades wildlife habitat.
  • Plants in excess quantity can be toxic to humans, horses, and livestock
  • Scotch broom usually reproduces by seed  and rarely reproduce vegetatively
  • Seeds can live in the seedbank for over 80 years!
  • One shrub can produce thousands of seeds (up to 15,000) after two years of growth.
  • Seeds can be transported over long distances by animals, humans, water, and vehicles.
  • Scotch broom can tolerate a wide range of environmental and soil conditions.
