Floristic diversity and demographic structure of the Sidi R'Ghies forest, north-eastern of Algeria

Abstract: Abstract. Rached-Kanouni M, Kara K, Khammar H, Ababsa L. 2020. Floristic diversity and demographic structure of the Sidi R'Ghies forest, north-eastern of Algeria. Biodiversitas 21: 875-881. In Algeria, the degradation of the ecosystems induces a loss of biodiversity and an increase in the adverse effects of climate change and anthropogenic actions, especially at the level of the ecosystems of semi-arid zones. This study aims to determine the floristic composition and demographic structures of different stands … Show more

“…In the present study, diversity was evaluated at stand level (α diversity) which represents the number of species in the stand, their proportion, as well as their distribution (Rached-Kanouni et al 2020a). Three of the distancedependent stand structure measures were thus used; the aggregation index by Clark and Evans, the species mingling index and the diameter differentiation index.…”

“…Vegetation data were calculated to obtain the values of density (individuals/ha), frequency (%), and dominance (m 2 /ha) (Kent and Coker 1992;Rached-Kanouni et al 2020). Important Value Index (IVI) was obtained by adding up the relative values of density, frequency, and dominance (Neelo et al 2015).…”
