The effect of the monoculture of Aleppo Pine in the high
plains of Saïda on biodiversity, richness and rate of endemic flora is the subject
of our study. For this purpose, 30 floristic surveys were carried out to
evaluate the biodiversity indices inside and outside the wooded sites.
Vegetation analysis using the TWINSPAN method resulted in two groups of
ecological species; the similarity study showed a clear separation between the
groups, the overall value of ANOSIM-R was 0.99 (P <.001). The average
species richness and the Shanoon index are 2.063, 2.23 higher in non-wooded
sites than in wooded sites respectively. The results of the survey indicated
the presence of 98 plant species. Among them, 14 species are classified as
threatened, endemic or rare. A total of 27 species has been eliminated by
reforestation, of which 11 are classified as threatened, endemic or rare. It is
therefore recommended that biodiversity should be taken into account in
afforestation operations in order to maintain natural habitats and minimize the
loss of native species.
