UK Biodiversity Indicators 2020. Indicator C4a – Status of UK priority species – Relative abundance 2020

Corporate UK Biodiversity


These documents support state indicator C4a – Status of UK priority species (Relative abundance). The documents include a datasheet and technical background document.

This indicator shows changes in the relative abundance of priority species in the UK for which data are available. The relative abundance of each priority species in this indicator is the estimated population (abundance) of that species in the latest year of the time series taken as a percentage of its estimated population in the earliest year of the time series (i.e. the base year). The indicator will increase when the population of priority species grows on average and decrease when the population declines.

This indicator should be read in conjunction with indicator C4b, which provides data on those UK priority species for which distribution data are available.

The UK Biodiversity Indicators were first published in 2007. They were created to provide a measure for reporting on the UK’s progress towards meeting international biodiversity goals and targets. The 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 developed in 2010 and 2011.
