A forest, also - referred to as a wood or the woods, is an area with a high density of trees. A forest may vary significantly in size and have different classifications according to how and of what the forest is composed. These plant communities cover approximately 94 percent of the Earth's surface (or 30 percent of total land area), though they once covered much more (about 50 percent of total land area), in many different regions and functions as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the biosphere. Although forests are classified primarily by trees, the concept of a forest ecosystem includes additional species (such as smaller plants, fungi, bacteria, and animals) as well as physical and chemical processes such as enenergy flow and nutrient cycling.
A typical forest is composed of the overstory (canopy or upper tree layer) and the understory. The understory is further subdivided into the shrub layer, herb layer, and also the moss layer and soil microbes. In some complex forests, there is also a well - defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon, aid in regulating the planetary climate, purify water and mitigate natural hazards such as floods. Forests can be found in all regions capable of sustaining tree growth, at altitudes up to the tree line, except where natural the environment has been altered by human activity.
The latitudes 10 north and south of the Equator are mostly covered in tropical rainforest, and the latitudes between 53N and 67N have boreal forest. As a general rule, forests dominated by angiosperms (broadleaf forests) are more species - rich those dominated by gymnosperms (conifer, montane, or needleleaf forests), although exceptions exist.
Forests sometimes contain many trees species only within a small area (as in tropical rain and temperate deciduous forests), or relatively few species over large areas (e. g., taiga and arid montane coniferous forests). Forests are often home to many animal and plant species, and biomass per unit area is high compared to other vegetation communities. Much of this biomass occurs below ground in the root systems and as partially decomposed plant detritus. The woody component of a forest contains lignin, which is relatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.
Forests are differentiated from woodlands by the extent of canopy coverage: in a forest, the branches and the foliage of separate trees often meet or interlock, although there can be gaps of varying sizes within an area referred to as forest. A woodland has a more continuously open canopy, with trees spaced farther apart, which allows more sunlight to penetrade to the ground between than (also see: savannah).
Among the major forested biomes are: rain forest (tropical and temperate), taiga, temperate hardwood forest, tropical dry forest.
Forests can be classified in different ways and to different degrees of specificity. One such way is in terms of the "biome" in which they exist, combined with leaf longevity of the dominant species (whether they are evergreen or deciduous). Another distinction is whether the forest are composed predominantly of broadleataftrees, coniferous (needleleaved) trees, or mixed. Boreal forests occupy the subarctic zone and are generally evergreen and coniferous.
Temperate zones support both broadleaf deciduous forests and evergreen coniferous forests. Warm temperate zones support broadleaf evergreen forests, including laurel forests.
Tropical and subtropical forests include tropical and subtropical moist forests, tropical and subtropical dry forests, and tropical and subtropical coniferous forests.
