Common Weeds

Invasive ivy strangling trees

Invasive ivy strangling trees

Our Invasive Species Program is concerned with many common invasive weeds, such as English ivy and Armenian blackberry, along with the EDRR (Early Detection-Rapid Response) weeds. It’s important to prevent invasive weeds from spreading, as they can easily push out important native plants, and upset the delicate balance needed to support healthy ecosystems for all plants and wildlife.

Here are the common weeds we can help you get rid of:

Himalayan (Armenian) and evergreen blackberry  (Fact sheet – English, Español)

Butterfly Bush

English holly

English and Irish ivy  (Fact sheet – English, Español)

Herb Robert

Italian arum

Lesser celandine  (Fact sheet – English, Español)

Old Man’s Beard or Traveler’s Joy clematis   (Fact sheet – English, Español)
