The habitats have been identified based on phytosociological analysis. New records are presented of rocky, meadow, woodlands and temporary ponds habitats, such as： Stipo bromoidis-Quercetum dalechampii （habitat： eastern white oak woods, 91AA＊）; Verbenion supinae （habitat： Mediterranean temporary ponds, 3170＊）; Campanulo versicoloris-Dianthion japigici （habitat： calcareous rocky slopes with chasmophytic vegetation, 8210）; Acino suaveolentis-Stipetum austroitalicae （habitat： eastern sub-mediterranean dry grasslands （Scorzoneretalia villosae）, 62A0）. Other information on their extension, major threat and suggestions of actions for their conservation are provided.展开更多
