Shamansir Mountain is a part of the Sarawat Mountains, western Saudi Arabia. The current study intends to investigate Shamansir Mountain's plant wealth as well as the impact of direction and height on the mountain's floristic makeup. The study's findings, which included 152 species from 124 genera and 46 families, demonstrated how diverse Mount Shamansir's vegetation is. More than 40% of all species found in the research area belonged to the Asteraceae, Poaceae, Apocynaceae, and Solanaceae families. The obtained results showed that the number of species, genera, and families increases with elevation. These increases from the lowest elevation to the greatest height were, respectively, 280.7%, 286.3%, and 100%. The results showed that the eastern side of the mountain had 36.8%, 27.7%, and 33.3% more species, genera, and families than the western side. Hemicryptophytes made up the smallest percentage of all life forms, at 3%, while therophytes made up the largest, at 44%, followed by chamaephytes at 25%. At 29.6% of all species recorded, the Saharo-Sindian chorotype has the greatest number of monoregional species. Despite Saudi Arabia's low endemic plant population, one endemic species-Teucrium popovii R.A. King-has been identified. Many of the recorded species are of high economic value. 22 wild crop-related species were discovered in the studied area, while medicinal species comprise 57.8% of the total species in the given list. The study recommends that the Saudi government designate Mount Shamansir as an environmentally protected region, according to the report.
沙曼西尔山是沙特阿拉伯西部沙拉瓦特山脉的一部分。当前的研究旨在调查沙曼西尔山的植物资源，以及方向和海拔高度对该山植物组成的影响。该研究的结果包括来自124个属、46个科的152个物种，展示了沙曼西尔山植被的多样性。研究区域内发现的所有物种中，超过40%属于菊科、禾本科、夹竹桃科和茄科。所得结果表明，物种、属和科的数量随海拔升高而增加。从最低海拔到最高海拔的增幅分别为280.7%、286.3%和100%。结果表明，该山东侧的物种、属和科分别比西侧多36.8%、27.7%和33.3%。地面芽植物在所有生活型中所占比例最小，为3%，而一年生植物所占比例最大，为44%，其次是矮灌木植物，占25%。在所有记录的物种中，撒哈拉-信德植物区系型的单域物种数量最多，占29.6%。尽管沙特阿拉伯的特有植物数量较少，但已鉴定出一种特有物种——波氏香科科（Teucrium popovii R.A. King）。许多记录的物种具有很高的经济价值。在研究区域发现了22种与野生作物相关的物种，而药用物种占给定列表中总物种的57.8%。该报告称，该研究建议沙特政府将沙曼西尔山指定为环境保护区域。
