In Crimean forests, these trees grow naturally: Q. pubescens, Q. petraea, Q. robur and Q. petraea subsp. medwedievii. The distribution of different types of Quercus and theirs satellites depends on climatic and soil conditions. The stands of Q. petraea are not productive enough: this area is dominated by plantations of IV-V bonitet classes. The age structure of natural forests of Q. petraea is dominated by stands of VII-XI age classes, occupying 82.6% of the area of stands of this species in Crimea. Age structure of forest stands of Q. pubescens, as well as Q. petraea is characterized by maldistribution. The extremely limited number of plantings under 50 years testifies to the demographic imbalance of natural populations of Q. pubescens and low level of natural revegetation processes. Currently, in the forest formations of Q. pubescens in Crimea the low-tree stands of vegetative origin are dominating. In the existing situation, plantings of Q. pubescens are losing their protective functions and degrading, especially in the southern macroslope of the main ridge of Crimean Mountains. Generally, the formation of oak forests of Crimea is characterized by an unsatisfactory state, which is related to the irrational forest management in the past.
