One of the most significant streams in the area is Wadi El Faregh, located south of the Setif Wilaya in eastern Algeria. It is 20 km wide and ranges in elevation from 915 to 1322 meters. The Wadi flows into the Soubella Dam after originating from Cherne. The climate around Wadi El Faregh is semi-arid, characterized by relatively low rainfall and dry weather, with cold winters. The soil composition is primarily limestone. In the study, 23 plots were used as a sampling method to evaluate vegetation and examine the distribution of perennial plant species in the region. A total of 102 species from 37 distinct families were identified. Among these families, Asteraceae was the most represented, accounting for 16 species. In terms of biological forms, therophytes made up 39% of all known species, making them the most prevalent category. Therophytes are plants with a short life cycle that complete their life cycle within a single growing season. The overall Shannon-Wiener diversity index was 2.39, and the Simpson index was 0.94, indicating that the diversity in the Wadi is relatively high.
