Gap disturbance patterns in an old-growth sessile oak (Quercus petraea L.)-European beech (Fagus sylvatica L.) forest remnant in the Carpathian Mountains, Romania

These results suggest that the current small-scale disturbance pattern dominating this old-growth forest is more suitable for shade-tolerant species such as European beech, accentuating the already steady decline of oaks in mixed sessile oak-European beech stands.
