The flora of Qatar includes more than 300 species of wild plants. Vegetation is extremely sparse in the hamada landscape due to the heavily weathered soil. A native species of tree, Vachellia tortilis (known locally as ''samr'')〔(【引用サイトリンク】title=Samr )〕 is well adapted to the desert environment and one of the most common forms of vegetation in the country.〔 Zygophyllum qatarense and lycium shawii also grow in this landscape.〔Casey & Vine (1992), p. 78〕 Shallow depressions referred to as ''rodat'' constitute a more varied selection of plants since rainwater run-off is more likely to accumulate. Ziziphus nummularia favors deeper soil in this type of habitat, whereas the grass ''cymbopogon parkeri'' is found in shallower soils. In the south of the peninsula, panicum turgidum and vachellia tortilis grow in the wind-blown soils.〔 ==Natural areas== Natural areas in Qatar include: * Al Shahaniyah Park in Al-Shahaniya * Al Wabra Wildlife Preservation 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Flora of Qatar」の詳細全文を読む スポンサード リンク
