UK Biodiversity Indicators 2020. Indicator C4b – Status of UK priority species – Distribution 2020

Corporate UK Biodiversity


These documents support state indicator C4b – Status of UK priority species (Distribution). The documents include a datasheet and two technical background documents.

This indicator measures change in the number of 1 km grid squares across the UK in which priority species were recorded in any given year. This is referred to as the ‘occupancy index’ and is effectively equivalent to changes in the distribution of priority species for which data are available. The indicator will increase when priority species become more widespread on average, and decrease when species become less widespread on average.

This indicator should be read in conjunction with indicator C4a which provides data on those species for which abundance data are available.

Department for Environment, Food and Rural Affairs, UK (2020). UK Biodiversity Indicators 2020.

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.
