Section 4 — Vegetation Tibet is often called the “Roof of the World.” Yaks graze in the highland meadows on the Plateau of Tibet, which lies more than 10,000 feet above sea level. CorbisTibet is often called the “Roof of the World.” Yaks graze in the highland meadows on the Plateau of Tibet, which lies more than 10,000 feet above sea level. CorbisThe vegetation [vegetation: all the plants and trees in an area] in Monsoon Asia varies as much as the region’s climate does. In the drier parts of the region, only desert scrub [desert scrub: a vegetation zone of mainly small trees, bushes, and other plants adapted to a dry climate; also refers to the type of vegetation in this zone] survives. But in the tropical zones, lush plants thrive and form thick rainforests [rainforest: a type of thick evergreen forest found in areas of heavy rainfall]. Elevation also has a big effect on Monsoon Asia’s plant life. Remember that in a highlands climate, temperature varies with elevation. Vegetation varies with elevation as well. The region’s highest mountains are so cold that they are covered by ice and snow. Very little can grow in this ice cap [ice cap: a climate or climate zone that is very cold all year with permanent ice and snow; also a permanent, dome-shaped covering of ice over a large area; also a vegetation zone that is too cold to support plant life] vegetation zone. South Asia The plant life of South Asia varies with the climates and the altitude. The driest land supports only desert scrub. Tropical grassland [Tropical grassland: vegetation or a vegetation zone of mainly grasses and scattered trees adapted to a tropical wet and dry climate] covers much of central India. Mixed forest [Mixed forest: a type of vegetation or vegetation zone that includes both coniferous and deciduous trees] appears on the lower slopes of the Himalayas. In the tro
