The ecoregion has 4,500 native vascular plant species, including 400 endemic species. [2] The forests on the lower slopes are mostly deciduous broadleaf trees, including the oaks Quercus robur, Quercus petraea, Quercus pubescens. Broadleaf sclerophyllous evergreen trees are found in southern valleys adjacent to Mediterranean-climate regions. [2]

The stone pine is a coniferous evergreen tree that can exceed 25 metres (80 feet) in height, but 12–20 m (40–65 ft) is more typical. In youth, it is a bushy globe, in mid-age an umbrella canopy on a thick trunk, and, in maturity, a broad and flat crown over 8 m (26 ft) in width. [ 2 ]
