Three-layered high forest (as cathedral forest in its mature stage) consisting of beech or beech with fir (A.
borisii-regis, A. alba), with added Acer heldreichii and Acer pseudoplatanus; at the upper forest line it is poorer
growing with a sabre-like growth of the stems due to the effects of snow; the shrub layer is weakly developed to
absent, and only stronger in regeneration stages; the herb layer is weakly developed (a maximum of 20 % coverage).
