roztoczański national park - Opis:
- The theoretical tree density in a stand was calculated using an equilibrium curve model. The Bukowa Góra forest (Roztoczański National Park) placed under strict protection was the object of the study. Calculations were made separately for the main species − fir and beech. The data on tree mortality rate and their diameter growth (or height in the case of low trees) collected in 1991, 1996 and 2001 on permanent sample plots were used. The correspondence between the actual and model tree density curves in diameter classes was confirmed only in the case of firs from the upper layer of stands. The shortage of firs (in comparison with the model data) and the excess of beeches in the regeneration layer in respect of thin and moderately thick DBH were confirmed by gradual changes in tree−species composition between 1991 and 2001.
