STUDY OF THE DYNAMICS OF NATURAL STANDS OF PINUS HALEPENSIS IN THE BENI OUDJANA FOREST (KHENCHELA, ALGERIA)Insaf Hani, Malika Rached-Kanouni, Hichem Khamar and Menasri AmmarAbstract Knowledge of population structure and spatial distribution is an indispensable step in the sustainable management of forest stands. This study consists of analyzing these parameters of Pinus halepensis populations in the Beni Oudjana forest. Subjective sampling on the basis of the main exposures of the forest (North, East, South and West) allowed the establishment of inventory plots of 500 m². Dendrometric measurements (diameter at 1.30 cm, total height, barrel height, total volume) on individuals with a diameter greater than or equal to 5 cm at 1.30 m from the ground were carried out in sixteen plots. The highest density (2010 individuals/ha) and the lowest values of diameter (9.8±11.9 cm), basal area (0.01±0.04 m2/ha) and total volume (0.2±0.8 m3) were obtained within the plots with western exposure. Analysis of diameter and height structures revealed an increase in the frequency of young trees in the plots with western exposure. This work, which provides an overview of the state of the floristic diversity of the Beni Oudjana forest, allows taking appropriate measures to safeguard our plant resources. |
