Wildlife of Yemen : ウィキペディア英語版 | Wildlife of Yemen
The wildlife of Yemen is substantial and varied. Yemen is a large country in the southern half of the Arabian Peninsula with several geographic regions, each with a diversity of plants and animals adapted to their own particular habitats. As well as high mountains and deserts, there is a coastal plain and long coastline. The country has links with Europe and Asia, and the continent of Africa is close at hand. The flora and fauna have influences from all these regions and the country also serves as a staging post for migratory birds. ==Geography== Yemen is in the southern half of the Arabian Peninsula, bordering the Red Sea, the Gulf of Aden and the Arabian Sea. The country is divided into four geographical regions: the Tihamah or coastal plains to the west, the western highlands, the central highlands, and the Rub' al Khali, or "Empty Quarter", in the east, the largest sand desert in the world. The Tihamah forms an arid flat plain alongside the Red Sea coast. There are many lagoons here and considerable biodiversity; streams from the western highlands sink and evaporate before reaching the coast.〔(Yemen country profile ). Library of Congress: Federal Research Division (December 2006).〕 The Sarawat Mountains (or Sarat Mountains) in Saudi Arabia extend southwards into Yemen, where they divide into two ranges. The western highlands run parallel with the Red Sea coast and to the east of them, the land slopes gently towards the Persian Gulf. These mountains receive up to of rain in places and are the wettest part of the country. Rainfall comes from southwestern monsoons and from thunderstorms in summer. For over two thousand years the steep slopes of these mountains have been terraced and intensively cropped, and little of the indigenous vegetation remains.〔(【引用サイトリンク】title=Arabian Peninsula: Yemen and Saudi Arabia: Deserts and xeric shrublands )〕 The central highlands rise up to over and contain the highest peaks of the Arabian Peninsula. They are in the rain shadow of the western highlands but receive enough rainfall for the cultivation of irrigated wheat and barley. The Rub' al Khali desert region receives almost no rainfall.〔 Both this range and the western highlands feature many wadis, dry watercourses which have been carved out by floods when the occasional torrential downpour occurs. These often support more vascular plants than other arid areas.〔
