What are invasive non-native species?

Over 2,000 plants and animals have been introduced to GB from all over the world by people. These are known as non-native species. Most are harmless, indeed the majority of our agricultural species (wheat, barley, sheep etc) are not native to GB, 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. Here in the UK, they threaten the survival of native wildlife, damage our natural ecosystems, cost the economy nearly £2 billion a year, and can even harm our health and interfere with activities we enjoy.

What is Invasive Species Week?

Each year organisations across the UK, Ireland, Jersey, Guernsey and Isle of Man work together to raise awareness of the impacts of invasive non-native species and the simple things that everyone can do to help protect the environment.
