Abstract

These documents support response indicator: B6. Pressure from invasive species. The documents include a fiche, datasheet and technical background document.

Non-native species are those that have reached Great Britain by accidental human transport, deliberate human introduction, or which arrived by natural dispersal from a non-native population in Europe. Species that have arrived since 1500 are included within this indicator. Most non-native species are considered benign or positive but some have a negative impact on native species through the spread of disease, competition for resources, or by direct consumption, parasitism or hybridisation; such species are termed invasive. Invasive non-native species have one or more of these negative impacts and a high capacity to spread to natural and semi-natural habitats. This indicator shows the change in number of invasive non-native species established across 10% or more of the land area of Great Britain, or along 10% or more of the extent of its coastline.

Lineage
The UK indicators were comprehensively reviewed during 2011 and 2012 to ensure they continued to be based on the most robust and reliable available data; and remained relevant to the new international goals and targets. Since then the indicators have been refined to improve their relevance/quality, and new indicators developed to fill gaps. In this version of the publication as many as possible of the indicators have been updated with new data. In some cases, however, development work is ongoing, and where this is the case, the work to develop them has been described briefly.
