Invasive Species Week 2024

Raising awareness of Northern Ireland’s invasive species

20th – 26th May 2024

Invasive non-native species are one of the top five drivers of global biodiversity loss and cost the Northern Ireland economy approximately £150 million a year and can even harm our health. Help us to protect our environment and wildlife by taking part in Invasive Species Week!

Last year over 260 organisations took part – if you or your organisation would like to join us in 2024, we’ve put together a list of daily themes and some event ideas for you to use.

Please let us know your plans by getting in touch via so we can add them to our events page.

Daily Themes

  • You can follow our daily themes for communications activities, or use your own: 
    • Monday – what are invasive non-native species (INNS)? It’s important to be clear about the difference between non-native and invasive non-native species.
    • Tuesday – How are they spread? Are there activities that you or your audience are involved in that are a particular risk?
    • Wednesday – Why are they a problem? How do they affect your local environment, sport, industry etc? We’ll also be looking at the links between INNS and climate change / biodiversity loss. 
    • Thursday – What is being done to prevent this? This is an opportunity to share what your organisation is already doing or what you plan to do in future. 
    • Friday – What can I do? What could your audience, staff, or members do to help? (See our five things that everyone can do for inspiration)
    • Saturday and Sunday – Activities to get involved in. Could you host an event? (See our list of ideas to help)
