Why can oak groves last?

Dubrava is a perfect and sustainable ecological system that can exist for centuries under constant external conditions. The biogeocenosis of oak groves comprises more than a hundred species of plants and several thousand species of animals. It is clear that with such a diversity of species that inhabit oak forests, it will be difficult to shake the stability of a given biogeocenosis by destroying one or more species of plants or animals. It is difficult, because as a result of the long coexistence of plant and animal species from separate species, they became a single and perfect biogeocenosis.
