Invasive Species Week

The first Invasive Species Week took place in 2015, bringing together a range of organisations to raise awareness of invasive non-native species and inspire people to #GetINNSvolved and stop the spread.

Invasive Species Week 2019

Invasive non-native species harm the environment and wildlife, are costly to the economy, and can even pose a risk to our health and way of life.

During Invasive Species Week, organisations across the UK, Ireland, Jersey, Guernsey and the Isle of Man are working together to raise awareness and ask everyone to help prevent their spread to protect the environment and recreational spaces for future generations to enjoy!

From 13 - 17 May we'll be taking a closer look at invasive species across a range of important environments:

Mon: Freshwater and riparian
Tues: Urban
Weds: Marine
Thurs: Woodland and bogs
Fri: Small islands

Follow along at @InvasiveSp and look out for events taking place throughout the week near you.

How can I get involved?

Getting ready for Invasive Species Week

Let your colleagues, visitors, volunteers, classmates know that Invasive Species Week is happening and encourage them to take part. Think about how you could raise awareness of invasive non-native species and their impacts during the week:

  • Include articles in your newsletter, website, blog, membership magazine, mailing list. Download our key facts to help. We’ve suggested some species to focus on but think about which of these are most relevant to you and the audience you’re trying to reach, local or business issues are likely to be of interest to them.
  • Order free copies of our poster and  postcard to display and hand out and display.
  • Arrange to give a talk or run a webinar (at work, museums, university, science club, school)
  • If you’re already involved in work on invasive non-native species, contact local media to raise awareness of the work you do.
  • Download our suggestions for how to get involved for other ideas.

During Invasive Species Week

  • Follow @InvasiveSp on Twitter and retweet posts, create additional posts of your own if you can. Remember to use #InvasivesWeek in your posts. Share infographics and materials online through any other online channels you have (website etc).
  • Share details / photographs of any events you’re taking part in, of invasive species impacts near you, any invasive species work you’re involved in, displays in your office, any good practice by colleagues and volunteers etc. Use #InvasivesWeek in any posts on social media.
