UK Biodiversity Indicators 2021. Indicator D1c – Status of pollinating insects 2021

Corporate UK Biodiversity


These documents support indicator D1c – Status of pollinating insects. The documents include a datasheet and technical background document.

This indicator indicates changes in pollinator distribution (bees and hoverflies) in the UK. The indicator is based on 377 species (148 species of bee and 229 species of hoverfly), and measures change in the number of 1 km grid squares across the UK in which they were recorded in any given year: this is referred to as the ‘occupancy index’. Many insect species are involved in pollination but bees and hoverflies are known to be important and are presented here as an indicator of overall pollinator trend.

The headline indicator for ‘all pollinators’ and the index for hoverflies have not been updated since the 2020 publication. However, the indicator time series for wild bees has been extended by one additional year (to 2019).

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.
