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 (www.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.
