Butterfly survival blueprint unveiled


December 2012. Restoring and joining up habitat will prevent the UK's threatened butterflies and moths from becoming extinct in the future, a ground-breaking report has revealed.

For the first time, the report by Butterfly Conservation provides concrete evidence that projects aimed at conserving butterflies and moths at a landscape-scale have enabled threatened species to flourish after decades of decline.

Whole landscape conservation
A landscape-scale approach works by improving and connecting land for wildlife by the coordinated conservation management of numerous sites for a range of species across a large natural area. The report, Landscape-scale conservation for butterflies and moths: lessons from the UK, also shows that measures to conserve rare butterflies and moths have helped other threatened species as well as the habitats in which they live.

Butterflies in decline
Butterflies are the most threatened wildlife group; more than three-quarters of Britain's 57 resident species are declining and over 40% are listed as Priorities for Conservation. More than 80 moth species are also at risk. Most threatened species are now confined to small patches of habitat that have been left isolated within the modern intensively managed countryside.

12 landscape scale projects
For over a decade, Butterfly Conservation has adopted a landscape-scale approach to conserving these areas in order to manage existing habitats more effectively and link them with newly restored habitats. This combination of targeted management and restoration has allowed many species to flourish in each of the 12 landscapes covered in the report.

Small blue
Examples include the Small Blue in Warwickshire which has increased from a low of three to eight colonies in just three years.
