Thank you for reporting your 2023 Invasive Plant Activity!

The CIPWG 2023 Annual Report is a compilation of reported invasive plant management and education activity for the 2023 year.

Read the 2023 CIPWG report HERE

The report details the invasive plant management and educational activities that occurred in over 60 CT towns throughout the year. At least 5,345 citizens directly and actively participated in the reported activities. Many (at least 4,670) were reached indirectly through articles, YouTube videos, social media, fact sheets, signs, and other educational mediums. A minimum of 30,765 hours were directly invested in invasive plant management, during intensive invasive plant training sessions and management activities, as well as educational outreach. A minimum of 5,300 hours were provided indirectly as citizens engaged in educational efforts and learned from videos, articles, and fact sheets.

The Connecticut Invasive Plant Working Group maintains the following subcommittees:

  • Education and Outreach (educational outreach about invasive species and their alternatives)
    • CIPWG display was used at 5 events around the state in 2023.
    • Outdoor Educators held 6 free “Walk, Talk and Cut” events in 5 of Connecticut’s counties.
      • 74 people attended these events.
  • Management (develop and disseminate information on invasive plant control options)
  • Native Alternatives (explore and promote use of native plant species as alternatives to invasives)
  • Research List Review
    • Met 5 times in 2023 to review CIPWG’s Research Plant List.
    • Made recommendations to the CIPWG Steering Committee regarding plants that should be recommended to the Invasive Plant Council for addition to the CT Invasive Plant list.
    • Developed protocol for annual review of the Research List.

CIPWG provides a List of Speakers who are available to give presentations on many invasive plant-related topics, including identification, control, and non-invasive alternatives. Since 2002, CIPWG has hosted biennial invasive plant symposia. Symposium 2022 information is available on the CIPWG website. Planning for the 2024 biennial CIPWG symposium has begun.

National Invasive Species Awareness Week

National Invasive Species Awareness Week (NISAW) was observed February 28 – March 4, 2022. NISAW is a nationwide event to raise awareness about invasive species, the threat that they pose, and what people can do to prevent their spread.

Everyone can play a role in managing invasive species. Here are some ways you can help!


  • Spotted lanternfly is one of our newest invasive species reported in CT. Now is a great time to learn about this pest. Learn about spotted lanternfly at: CAES Spotted Lanternfly Information.

If you’re planning to plant in your yard this year, choose native species whenever possible. For information and resources, refer to: 


MORE TIPS FROM PLAY CLEAN GO (playcleango.org) for preventing the spread of invasive species when recreating in the outdoors:

  • REMOVE plants, animals and mud from boots, gear, pets, and vehicle.
  • CLEAN your gear before entering and leaving the recreation site.
  • STAY on designated roads and trails.
  • USE CERTIFIED or local firewood and hay.
