Non-native Species Fact-file

The Audit of Non-native Species in England (2005) reported a total of 2721 non-native species and hybrids present in England, with 1413 species after garden animals, fungi and rarer vascular plants were removed. In a similar survey, the Audit of Alien Species in Scotland (2001) reported 988 non-native species (not including fungi). However, only a small minority of non-native species become invasive, posing a threat to the environment and the economy. The majority of non-native species are beneficial to man e.g. most of our crops and domestic animals.

From this page you can link to individual species fact sheets from which you can find out more information on about particular non-native species - how they got here, the impacts they can have and what is being done or can be done to reduce the problem.

Note: New sheets are being added as they become available so remember to come back if the species you are looking for is not yet there. If you feel that we have missed something important,

THE NNS Secretariat is collecting ionformation on research, monitoring or management (control) directed towards non-native species in Britain. Our aim is to capture a range of details that allow us to measure how much action against non-native species is occurring, how this is split between species and crucially how much this is costing.
