Classification depends mainly forests position, distance from equator, altitude and climate.
Tropical forests - all year round temperatures are high and precipitation. Tropical moist forests are found near the equator. In tropical forests there is a season of drought. Most trees have crown umbeliforma. Flowers in tropical forests are pollinated by insects, birds, animals. The wood structure of trees is excellent, being strong and tough, with high resistance.
Sub-tropical forests - are found north of the tropical forests. Trees are drought tolerant summer.
Temperate forests - are found in eastern North America, Asia, North-eastern, eastern and western Europe. Temperate forests are a mixed and coniferous species decidue. Seasons are well defined.
Mediterranean forests - are found south of temperate regions, the Mediterranean Sea coast, in California, Cs and Western Australia. Vegetative cycle is short and almost all trees and shrubs are evergreen, but in combination with coniferous and leafy trees fell.
Coniferous forests - are found in cold regions, near the poles. Conifers are adapted to drought.
Mountain forests - are found in the temperate zone, subtropical and tropical high altitude. Plants are adapted to withstand cold, rain and intense sun light. Conifers predominate.
