Abstract

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

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.

Lineage
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.
