Un Sistema di aree di interesse botanico per la salvaguardia della biodiversità floristica della Sardegna
This work focuses on environmental conservation studies realized in Sardinia within last thirty years, mainly concerning to botanical aspects. The study about botanically- sensitive areas, in the context of the planning of Regional Landscape Plans (Piani Paesistici), pointed out 135 biotopes of great floristic and vegetational concern. Consistency, specificity, rarity, use, institutional resource values as well as hazard rate of the areas (mapped 1:100,000) have been defined. Furthermore, a 20-criteria table has been drawn up for an objective definition of conservation-worth areas. Main botanical features and bibliography, if it does exsist, are mentioned for every biotope. Endemic species, rareties, phytogeographically important ones and principal vegetation types are mostly included in this systemlike
frame that incorporates a significant part of Sardinian floristic districts and phytoclimatic areas. Thus, a wise conservation policy for these areas, representing about 10% of the total regional land, would guarantee the conservation in time of the most significant botanic resources
