Introduction
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% spread and become invasive non-native species (INNS) which harm wildlife and the environment, are costly to the economy and can even impact on our health and way of life.
A study in 2021 assessed the economic cost of INNS to the UK economy since 1976 to be between £5.4 and £13.7 billion. A combination of social and environmental problems caused by INNS makes it clear that action to control their spread, while challenging, should be taken if possible.
