Save the date! Invasive Species Week 2026 will take place from 22 to 28 June 2026.
Invasive non-native species (plants and animals) threaten the survival of native wildlife and our natural ecosystems, cost the economy nearly £2 billion a year, and can even harm our health and interfere with activities we enjoy.
Invasive Species Week is an annual event to raise awareness of invasive non-native species and how everyone can help prevent their spread.
What's happening?
Each day we will focus on a different theme:
- Mon 22 June: Welcome to Invasive Species Week!
- Tue 23 June: Volunteering and recording
- Wed 24 June: Check Clean Dry
- Thu 25 June: Be Plant Wise
- Fri 26 June: Responsible pet ownership
- Sat 27 and Sun 28 June: Take part!
Register to attend our webinars.
