Invasive Species Week 2021

Invasive Species Week is an annual event led by the NNSS to raise awareness of invasive species and how everyone can help to prevent their spread.

The most recent Invasive Species Week took place from the 24-30 May 2021.

Throughout the week lots of events and activities were held online and socially distanced, from blogs and webinars, to games and quizzes. We reached many more people on Twitter than in the previous Invasive Species Week held in 2019, and had a great response to our videos and webinars. You can still find links to most of the activities and materials.

Many of the fantastic Local Action Groups still managed to get out in the field with their volunteers to remove invasive plants, and a new national initiative was launched to tackle floating pennywort with the help of volunteers.

How can I protect the environment?

If you missed out this year, check out our video (right) to learn about what invasive non-native species are, why they are a problem, and what you can do to help.

There are five simple things that you can do to help prevent the spread of invasive non-native species:

  • Keep any boats, clothing, footwear and equipment used in water free of invasive non-native species – remember to Check Clean Dry after use. 
  • Be Plant Wise and don't let your pond or aquarium plants enter the wild.
  • Take care of your pets, never release them or allow them to escape into the wild. It’s cruel and could harm other wildlife.
  • Look out for Asian hornet and other alert species and record your sightings. Read more on Asian hornet and how to report sightings, find free ID sheets for invasive non-native species and download the Asian Hornet Watch app.
  • If you enjoy being outside why not join a Local Action Group working on invasive species management.
