Abstract: | The objective of this study is the rational management of forest ecosystems for the sustainable conservation of plant biodiversity. Two types of analysis are carried out: the structural analysis and the analysis of the main species. In total, 3675 individuals are distributed in 5 families, separated between 7 species were identified. The dominant woody and grassy plant species are Pinus halepensis and Juniperusoxycedrus. Pinaceae and Cupressaceae are the most represented families. Mean values of species richness, Shannon diversity index are 3±1,2 et 0,71±0,30 species / plot respectively. The average density of woody trees in the Sidi R’Ghies forest is 735 ± 368 plants / ha with an average basal area of 23,01 ± 5,04m² / ha. The structure of the heights shows that the trees in the height classes between 2 and 4m have a very high density, proof of a natural regeneration. The total structure indicates that smaller trees are more abundant than larger ones (17,5 <d≤27,5cm). Indeed, this work is a database for the forest but it is only one of the facets to be considered in order to protect and restore it. |
