الوضعية الايكولوجية لبعض المناطق الرطبة في منطقة وادي ريغ

Abstract

The Oued Righ region has many wetlands that play an important ecological role through relationships with the region's ecosystems. The objective of this work is to study three wet areas (lakes) located along the Oued Righ and determine the ecological status of these areas and their biotic and abiotic characteristics.The studied areas were represented in three lakes: Merdjadja, Meggarine, Ayata, including classified and unclassified with RAMSAR. During the study, we collected climatic data for the Wadi Reg region during a period extending from 2011 – 2021, and it turned out that the climate of Wadi Reg was hot and dry in summer and cold in winter, according to Q EMBERGER. The results of the physical analysis of lake water showed that we observed a large convergence in the measurements of PH, water temperature, and turbidity, as well as the percentage of oxygen and the percentage of dry matter. The results of the study of the vegetation cover of the studied wet areas confirmed that it is home to 24 plant species whose distribution varies according to the study stations. Resistance to salinity and drought in these wetlands. However, we note a lack of plant diversity due to the preparations that affect the surroundings of these areas from time to time. Through this work, we can say that the ecological status of the studied wetlands is generally similar in results, with a difference in some types of their Conserving these areas requires more research, study and vegetation cover. awareness of their environmental importance.
