Abstract:
The study site was on the 16th Tishreen dam in Lattakia in 2021-2022 in the spring and autumn seasons, which aimed to knowing the changes in the plant biodiversity resulting from the construction of 16th Tishreen dam. This study was carried out in three different locations: riverbed before the lake, 16th Tishreen lake and the riverbed after the dam (8 replicates were taken for each site) in addition to studying the effect of distance from the bank, where this factor was taken to seven different distances. The results showed in the spring season that there were significant differences between the site according to the specific richness, as 60 plant species were recorded on the riverbed before the lake, 67 plant species on the 16th Tishreen lake and 34 plant species on the riverbed after the dam. This result was confirmed by Shannon’s wiener, as the value of plant community coverage recorded 4.04 on the riverbed before the lake, 3.71 on the 16th Tishreen lake and 3.34 on the riverbed after the dam, this mean the number of plant species decreased by half in the sites after the dam in comparison with sites before the dam. While no significant differences were recorded according to the distance from the bank. As for the analysis of the results in the autumn season, no significant differences were recorded between the sites nor according to the distance from the bank when conducting the analysis according to the specific richness and Shannon’s wiener.
Keywords: Plant biodiversity, 16th Tishreen dam, riparian plants.
