We have been helping the Peatland Partnership on their proposed bid for a UNESCO World Heritage Site in the Flow Country of Caithness. The blanket bogs in this area are amongst the largest in the world. Our role at this stage was to identify all the peatland macrotopes present, using an agreed spatial algorithm, then create a set of maps on GIS for the partners to use during a forthcoming consultation with landowners and communities. Following completion of the consultation stage, a formal application will be developed and sent to the Department of Media, Culture and Sport in London for consideration before being submitted to UNESCO.
