To determine the characteristics of population loci of linden and elm in bottomland with short-term flooding and middle land ecotopes and at different cover of canopy, 132 test areas were laid on 0.04 hectares; surveys were conducted with the definition of developmental states and measuring the size of the trunks and crowns. Accounting revealed that individual linden is always higher than individual elm in the same developmental states. In bottomland ecotopes with short-term flooding population loci of limes dominate over elm loci not only in height but in numbers; in such circumstances, development of elm to generative stages of ontogeny is usually impossible and in the future its expulsion the stand will take place.

Старовозрастные леса - важный объект в исследованиях лесных сукцессии. Их изучение дает информацию о результатах предшествующей долговременной динамики и создает основу для прогноза динамики на период предстоящей смены поколений древостоя. Ключевой компонент лесных сообществ - популяции древесных
