Abstract

The current study aims to comprehend the working processes of unique daya ecosystems by comparing the ecology of two Pistacia atlantica Desf. located in distinct geomorphological and bioclimatic contexts within the Djelfa province. We performed a floristic inventory of two sites by identifying the plant groups that characterize them individually using a correspondence factor analysis, and emphasizing the primary ecological gradients that control their distribution. Eighty phytoecological surveys have been conducted in order to achieve this goal. The 106 species found in our surveys exhibited a notable diversity of families and genera, with a prevalence of Asteraceae, Poaceae, Fabaceae, and Brassicaceae. Examining the biological spectrum showed that Therophytes were predominate, followed by Hemicryptophytes and Chamephytes, indicating that the environment is deteriorated. The primary ecological gradient identified by the correspondence factor analysis results is the geomorphological component. This would affect the moisture content of the soil and how plants are distributed. It is feasible to differentiate between the ecosystem of daya Bentoumi, which are less deteriorated, and the ones of Boucedraia, which are more degraded because of the gradient of anthropogenic disturbances.
