UK Biodiversity Indicators 2023. Indicator B6: Pressure from invasive species 2023


Updated 14 November 2023.

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

Non-native species are those that have reached Great Britain accidentally on human transport (e.g. ships, planes), or have been deliberately introduced. Others may have arrived naturally, but 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. Non-native species are considered to be ‘invasive’ if they have a negative impact on native species 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.
