A forest is defined as the area of land that is covered by trees. The Food and Agriculture Organisation of the United Nations defined forest as Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in this situation. It does not include land that is predominantly under agricultural or urban use. By using this definition, Global Forest Resources Assessment 2020 has concluded that the total forest lands cover about 4.06 million hectares or 10 million acres of land which sums up to 31 of the total land on the Earth’s surface in the year 2020. Forests are important for the survival of all living beings. They are vital for our life as they provide oxygen, food, shelter, fuel, and means of livelihood for the tribal people living in and around the forest area. Forests are home to 80 of the global terrestrial biodiversity and are the source that fulfills all basic needs for adjacent human settlements. Everything from the oxygen we breathe to the wood used from fuel to use in construction comes from forests. It is a self-nourishing system, which is a host to a number of organisms. The ecosystem of every forest includes both biotic living and non-biotic components. The biotic components include plants, trees, shrubs, vines, grasses, mosses, algae, fungi, insects, mammals, birds, reptiles, amphibians, and microorganisms. Forests are primarily referred to as the terrestrial ecosystem of the Earth. They are widely spread all over the surface of the Earth. The majority of the forest land is concentrated in just 5 major countries and those are Brazil, the United States, China, Canada, and the Russian Federation. About 45% of the forest land that is the largest forest share is in the tropical zone followed by temperate, boreal, and subtropic domains. Thus, the forests are divided into three major types as follows. The temperate forest is further divided into two subcategories and those are temperate deciduous forests and temperate coniferous forests. Temperate deciduous forests are mostly found in Japan, China, Europe, and a few parts of Russia as well as in the eastern part of the United States and Canada.
