Non-native species

Non-native species are the second most serious threat to global biodiversity after habitat loss. Islands, freshwater and coastal waters are most at risk. Non-native species cost the Scottish economy around £264 million each year.  We can all do something to help stop their spread.

The Code of Practice on Non-Native Species sets out a framework of responsibilities for bodies with powers relating to non-native species.  SNH is the lead organisation for non-native species in terrestrial habitats, including wetlands and bankside vegetation, and all terrestrial vertebrates and invertebrates.
