UK Biodiversity Indicators 2023. Indicator C2: Habitat Connectivity 2023


This indicator was not updated in 2023. It was last updated in 2019.

These documents support state indicator C2 – Habitat Connectivity. The documents include a datasheet.

This indicator is currently under development, and an official statistic under development has been produced.

Connectivity is a measure of the relative ease with which typical species can move through the landscape between patches of habitat. Habitat loss and fragmentation can reduce the size of populations and hinder the movement of individuals between increasingly isolated populations, threatening their long-term viability. This indicator illustrates changes in functional connectivity – the ability of species to move between resource patches – of 33 butterfly and 29 woodland bird species in the UK. The indicator is based on a measure of population synchrony, which is the level of correlation in time-series of population growth rates from different monitoring sites. Quantifying functional connectivity will allow more targeted landscape conservation management to help reduce the risk of species extinction.
