Description
The potential wetlands of Brittany occupied by developments or uses that may alter their functions are derived from crosses between potential wetlands (Agro-Transfert Bretagne, 2008) and data corresponding to different categories of possible alterations, identified in Brittany:
— artificialisation, including urbanisation and transport infrastructure;
— the creation of bodies of water or artificial basins;
— cultivation;
— forest plantations of softwood and poplar;
— the cumulation of the previous 5 fittings or uses.
Thus, 12 data are made available:
— the crossing between the ZHPs and urbanisation + its distribution by water body catchment areas
— the crossing between the ZHPs and the transport infrastructure + its distribution by water body catchment areas
— the crossing between ZHPs and artificial water bodies or basins + its distribution by water body catchment areas
— the crossing between the ZHPs and the cultivated areas + its distribution by water body catchment areas
— the crossing between ZHPs and forest plantations + its distribution by water body catchment areas
— the crossing between the ZHPs and the cumulation of the 5 developments or uses + its distribution by water body catchment areas
These data have been produced as part of the report “Wetlands of Brittany — State of the alterations, Restoration issues”, available at the following link:

A detailed description of the method used is available on pages 94 to 104.
