What Is an Invasive Species?

A non-native species that:

  • has spread into native or minimally managed natural systems
  • has developed self-sustaining populations by becoming dominant and/or disruptive to native systems
  • has no natural pests/predators
  • causes environmental or economic harm

Invasive insects and animals are brought on packing materials, imported products, or as exotic pets. 

Many invasive plant species were originally brought here as ornamental plants. You many have some of them in your yard, like burning bush, bush honeysuckle or Japanese barberry.

As you can see from the images on the right, these are the plants you see taking over utility poles and untended property.

What Can be Done About Invasive Plants?

Remove Them from Your Property

Removing vegetation, including invasive species, in or near wetlands, streams, and vernal pools, is regulated by the Massachusetts Wetlands Protection Act and the Lexington Wetlands By-Law and may require review by the Lexington Conservation Commission. Please contact the Conservation Division before removing any plant material from the above mentioned resource areas.

You can report invasives when you find them on public land, using an online for or a smarphone app.
