For one week every year, organizations across Ireland, the UK, Isle of Mann, Jersey and Guernsey come together for a week of action to raise awareness on invasive alien species and actions to prevent their spread. Invasive Species Week is led by the the GB Non-native Species Secretariat.

Last year over 260 organisations took part across all eight British Irish Council (BIC) administrations.

Invasive Species Week 2024

Invasive Species Week 2024 will be held during the week beginning May 20 – 26th 2024

Many people aren’t aware of invasive alien species and the harmful impacts they can have, or how we can all help to prevent their spread. Take part in Invasive Species Week 2024 and help protect the environment and recreational spaces for future generations to enjoy!

If you are planning an event, let us know and we will highlight it. Just email: [email protected] and put IAS Week in the subject line.
