The spontaneous vegetation is mostly constituted by spiked trees, bushes and shrubs such as rosemary. Of the old arboreal dome only small areas still have Portuguese oak and holm oak. The olive tree associated with crops that aren’t water demanding is the dominant element of non spontaneous vegetation. We can also find species such as Snapdragon and Paeonia Broteri between many others found in the region.
Such richness and diversity can be observed and felt around the caves entrance in the “Jardim dos Cheiros” (Scent Garden) where aromatic herbs both medicinal and culinary that grow spontaneously across the Aire Mountain are dully identified by their scientific and traditional name as well as way of use.
