Invasive Species Week
Invasive Species Week 2026
For one week every year, organisations 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.
Invasive Species Week 2025 will take place from the 22nd to the 28th June.
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.
Many people aren’t aware of invasive species and the harmful impacts they can have, or how we can all help to prevent their spread. Take part in Invasive Species Week 2026 and help protect the environment and recreational spaces for future generations to enjoy.
