Description
To better understand and manage the forest vegetation of the Saïda district
(types of vegetation present, floristic compositions, possible types of
degradation), a total of 215 phytoecological surveys were carried out in the
study area. In each survey, the intensity of the grazing and the presence or
absence of regeneration of the tree layer were noted. The plant groups were
determined using a modified TWINSPAN classification. For each vegetation
group, the diagnostic species were selected based on their fidelity index
(phi coefficient). We identified 9 plant groups and selected 147 diagnostic
species. The results of this study showed that in the surveys carried out, there
were more than 80% of moderately to heavily grazed, while in more than
70% of the studied plots, there was no regeneration of the main tree species.
This alarming situation implies the rapid and effective implementation of
protection and conservation measures.
