The conservation organisation Buglife has recently launched a one-stop shop for information on brownfield sites and their resident invertebrates. The Brownfield Hub is intended to help anyone – from ecologists to planners, developers to wildlife lovers – to understand the value of brownfield sites for our rare British invertebrates.
A brownfield site is a piece of land that has been altered by human activity, but which is not currently in use. Brownfield sites offer a precious ‘mosaic’ of habitats, providing variety that is rare in the wider landscape and can support important populations of scarce invertebrates.
On the Brownfield Hub are a series of downloadable PDFs which highlight the importance of these habitats for rare wildlife, how to identify open mosaic habitats on previously developed land, and how to manage them for key invertebrate groups. There are also useful case studies of Buglife’s work.
