Trees by nature, generally grow bigger and taller than other species of the vegetation. In general, the ecological zones of the world have been classified and differentiated mainly by the species of trees that they are made of. Although, usually, other factors are commonly considered in delineating the world into ecological zones. There are various species of trees, and what species are native to any one location depends on several factors. Each type also has particular structural features that differentiate it from the others. See alsoreference‘
Fast Growing Trees for Shade
Chilean Mesquite. This forest tree species scientifically known as Prosopis chilensis is native to South America such as southern Peru, Argentina, and Bolivia. It is a desert tree that is well known for its wide, bright-green, fern-like canopy. It also has numerous branches and dense canopy that spreads out close to the ground.

Generally speaking, all trees are important. Thus, it cannot be said that certain species are better than the others except for the particular use being considered. The use to which a tree species is put to therefore will normally depend on physical and structural features of the tree species. Trees have medicinal, constructional, and environmental uses such as wind breaks, soil canopy, and sun shade. Trees also serve as shelter for animals in many forests.
