In the monsoon forest are thicketsBamboo - plants, feels good in the subtropical and tropical zone and forming a whole grove. Bamboo - a very useful plant on the farm: for example, hollow stems can be used as water pipes, and some of his views a specially grown bent, then use for furniture productionand decoration. At the falls so much precipitation, that in some places the water for a long time remains on the soil surface. They look very different in the dry season, when due to lack of water and excessive heat native plants shed their leaves and covered with magnificent flowers. The equatorial forest is still in perfectrium, but its ecosystem is extremely sensitive to external influences. To completely restore the destroyed forest fragment, it takes at least several years, and after all the rain forest areas that have been converted into fields, rapidly become completely unusable, as poor soil completely eroded. Every year thatThus so destroyed vast areas of rainforest that after a few years it may lead to their extinction. Baobabs give a unique view of the African plains.

For the natives of these unusual plants are mythical trees inhabited bydeities and spirits, and shamans use pieces of bark and branches of baobabs for medicinal purposes. In decayed trunks before burying the dead, whose bodies did not decompose, and dry. Baobab fruit are very fond of eating baboons, hence the nickname of the cucumber-like formations - « monkey bread & raquo ;. The most characteristicth representative monsoon forests, widespread from India to Thailand - teak. This kind of makes the wood extremely water-repellent and resistant to fungus, which for centuries has been used for the construction of ships. Near the teak often grow ebeny. In America, the growing importance to the economy of mahogany, and AfRica - t. n. African mahogany, or kaya. In monsoon forest are common terminals, jujube, or jujube, Dahlberg, or rosewood and Callesium grande. In subequatorial climates where rainfall drops to 250-900 mm per year, and during the rainy season is short and irregular, monsoon forests turn into suChi forest and dry bushland. In the mountains of Central America and Southeast Asia, depending on local conditions often found « mosaic » of the monsoon and dry forests. In the dry forest trees get the minimum number required for the life of the water. Savannah - a grassy plain, nand which grow individual trees or shrubs, mostly acacia, eucalyptus and baobabs. They occur in tropical climates - particularly in Africa, Central and in the central and western Australia.

A small number of trees in the savannas ofbyasnyaetsya human activities and regular droughts - or, on the contrary, an excess of water in the wetlands. Most savannah formed as a result of burning and destruction of evergreen rainforest, as well as the monsoon and dry forests; Nevertheless, the results of pollen found inAfrican lakes suggest that savanna existed in these areas before the advent of man. There are several types of savannas. At the site of the equatorial forests formed moist savanna dominated by high (1.5 m) of herbs - such as Imperata cylindrica.
