沙特阿拉伯干旱地区的天然林,从南方的也门领土延伸到北方方塔伊夫。经调查其面积约为762,474公顷。主要树种是非洲桧(Juniperus procera),在一部份森林中还混生着相思树鸽之一种(Acacia spp)和金叶齐墩果(Olea chrysophylla)。这片森林过去被无限制的林区放牧和滥砍滥伐,目前正在为拟定一个保证木材连年生产量的管理计划而进行着深入细致的调查研究。一个以保护环境为目的,在王国全国范围内植树造林的方案正在实施。沙特阿拉伯约占阿拉伯半岛的五分之四。它的陆地总面积约为2.2亿公顷。沿海的平原是狭窄的,而东面平原较宽,多数地方低于海拔200公尺;整个西部有一系列海拔超过900公尺的山岳和高原。山脉在麦地那附近被山凹切割。一片海拔超过1800公尺的高地从塔伊夫向南穿过哈利进入也门领土。
Natural forests in arid regions of Saudi Arabia extend from the Yemeni territory in the south to Taif Yifu in the north. After investigation, it covers an area of about 762,474 hectares. The main species is the Juniperus procera, a species of Acacia spp and Olea chrysophylla that are also mixed with some forests. Pasture was pastured and deforested in an unconfined forest area and a thorough and detailed investigation is under way to develop a management plan to ensure the annual production of timber. A program of tree planting and afforestation in the kingdom nationwide is under way for the protection of the environment. Saudi Arabia accounts for about four-fifths of the Arabian Peninsula. Its total land area is about 220 million hectares. The coastal plains are narrow, while the eastern plains are wide and most are less than 200 meters above sea level; there are a series of mountains and plateaus above 900 meters above sea level across the west. The mountain range was cut near the medina by the hillock. An upland of more than 1800 meters above sea level crossed Ta’if from south to Yemen territory.
