Dynamics and development patterns of Pinus sylvestris L. - Fagus sylvatica L. stands in Central Rhodope

---

Abstract

The  study was conducted in second growth stands in the central Rhodope mountains  and    (specially) in the region of Xanthi. In order to determine the dynamics and  the development    patterns of Pinus sylvestris - Fagus sylvatica stands, 39 plots were established, trees were cut,    increment cores were taken, and stem analysis was conducted in 4 couples of  dominant    (competitive) pine and beech trees. The main results of this research  indicate that a) The    population structures, the regeneration and development patterns are  strongly influenced by    human and natural disturbances and species 'life history characteristics'.  b) The difference in    site quality between site types results in differences in the duration of  beech invasion (under pine) and in species basal area distribution. c) In good site qualities when individual dominant    beech and Scots pine (competitive) trees with a small age difference grew  together, the beech    trees, in some cases, have almost the same height growth as the pines and  the pine trees    showed a delayed (for the species) culmination in current annual volume  increment which is not    followed by a abrupt fall. d) The process of secondary succession is  influenced by disturbances    regime, environment, propagule availability and species biology.
