UK Biodiversity Indicators 2023. Indicator B4: Pressure from climate change (Spring Index) 2023

Abstract

Updated 14 November 2023.

These documents support context indicator B4 – Pressure from climate change (Spring Index). The documents include a datasheet and a technical background document.

This is a context indicator and is not assessed; it is shown to highlight a biological response to climate change and a potential pressure on biological systems. It shows the impact of temperature change on the timing of biological events such as flowering or migration in the spring. The UK Spring Index is calculated from the annual mean observation date of the following four biological events: first flowering of hawthorn (Crataegus monogyna), first flowering of horse chestnut (Aesculus hippocastanum), first recorded flight of an orange-tip butterfly (Anthocharis cardamines), and first sighting of a swallow (Hirundo rustica).
