FORESTS -and its types

FORESTS Forest is an area of high density of trees Forests occupy approximately one-third of Earth's land area, account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things.

Classification Of Classification of FORESTS TROPICAL TEMPERATE BOREAL

FOREST MANAGEMENT The scientific study of forests is referred to as forest ecology, while the management of forests is often referred to as forestry Forests can be altered when logging, forest fires, acid rain, cause damage to trees. In the United States, most forests have historically been affected by humans to some degree

DEFORESTATION Deforestation is the conversion of forested areas to non-forest land use such as arable land, urban use, logged area or wasteland. The largest cause as of 2006 is slash-and-burn activity in tropical forests. Slash-and-burn is a method sometimes used by shifting cultivators to create short term yields from marginal soils.

EFFECTS Loss of Wildlife Landslides Soil Erosion Hydrological Cycle SOLUTIONS Farming Forest Management Reforestation
