Forests and Grasslands			Description
			Tropical Evergreen Forests : These forests are also called tropical rain forests. These forests are found in those areas which receive over 200 cm of annual rainfall. These thick forests occur in the region near the equator and close to the tropics and also known as Equatorial Forests Trees like Rosewood, Ebony and Mahogany are found here. These forests are found in the Amazon basin of South America, Zaire(Congo) basin of Africa, New Guinea and western Ghats and Assam areas of India.
			Tropical Deciduous Forests: The trees of these forests shed their leaves during the dry season. Tropical deciduous forests are the monsoon forests found in the large part of India, northern Australia and in central America. These regions experience seasonal changes. Examples of trees found in these forests are Teak, Neem and Shisham.
			Temperate Evergreen Forests: These forests grow in the Northern as well as the Southern hemisphere. The temperate evergreen forests are located in the mid-latitudinal coastal region. They are commonly found along the eastern margin of the continents. They comprise both hard and softwood trees like Trees like oak, pine and eucalyptus, etc.
			Temperate Deciduous Forests: These forests grow in areas between 30o to 60o latitudes having West European type of climate. As we go towards higher latitudes, there are more temperate deciduous forests. These are found in the northeastern part of USA, China, New Zealand, Chile and also found in coastal regions of Western Europe. They shed their leaves in the dry season. Examples of trees found here are oak, ash and beech.
			Grasslands: These occur on either side of the equator and extend till the tropics. This vegetation grows in the areas of moderate to low amount of rainfall.
			Coniferous Forest: In the higher latitudes(50 0 -70 0 ) of Northern hemisphere the spectacular Coniferous forests are found. These are also called as Taiga. These forests are also seen in the higher altitudes. Chir, pine and cedar are important varieties of trees found here.
