Gap analysis comparing protected areas with potential natural vegetation in Tuscany (Italy) and a GIS procedure to bridge the gaps

摘要: The aim was to compare the protected area (PA) network in Tuscany, Italy, with areas referenced different types of potential natural vegetation (PNV), determine whether they are adequately represented for plant and habitat conservation purposes. For PNV, an existing but slightly updated modified Italian Vegetation Series (VS) map used. Each VS type corresponds complexes that live under homogeneous environmental conditions can each be considered ecological land unit at working scale employed here. Using GIS techniques, geographic layers PAs were processed spatial intersection extract quantify contained within boundaries PAs. As a minimum goal, we used widely accepted 10% target threshold. It found that, even though Tuscan covered almost 20% total surface, 94% resulted included percentage least their area. survey shows with...
