Non-native species are those which have been introduced to areas outside their normal range by human action. There are almost 2,000 non-native species established in Britain.
Most of these do not cause problems, but around 10-15% of non-native species in Britain have become invasive, i.e. have spread and had a negative impact on the environment, the economy, our health or our way of life.
These are a significant problem leading to dramatic decline in some native species, driving global biodiversity loss and costing the British economy.
FSC Centres are fully aware of good biosecurity practices to reduce the spread of non-native species, and work to record native species.
