Invasive Species Week
This week (20-26 May) organisations across the UK, Ireland, Isle of Man, Jersey, and Guernsey are working together to raise awareness of invasive non-native species, their impacts, and the simple things that everyone can do to help prevent their spread.

What are invasive non-native species?
Over 2,000 plants and animals have been introduced to Britain from all over the world by people. These are known as non-native species.
Most are harmless but around 10-15% become invasive non-native species which spread and have a harmful impact. Invasive non-native species:
- are one of the top five drivers of global biodiversity loss
- threaten the survival of native wildlife and damage our natural ecosystems
- cost the British economy nearly £2 billion a year
- can even harm our health and interfere with activities we enjoy
