Foothill forests below 600–650 meters elevation are mostly of broadleaf deciduous trees, principally English oak (Quercus robur), small-leafed lime (Tilia cordata), and European hornbeam (Carpinus betulus) in the northern portion of the range, and oaks – Quercus sessilis, Quercus cerris, Quercus pubescens, and Quercus frainetto – in the southern portion of the range.
