Conifers are cone bearing trees. Conifers include pines, firs, redwoods etc. There is a broad band of coniferous forests that stretches around the world just below the Arctic Circle. Most conifers are evergreens. This does not mean that their leaves never fall off. In fact each leaf of a conifer lives for about three or four years. Conifers are the largest and oldest trees in the world. The coast redwoods that grow on the coastal plains of California, USA, are the world's tallest trees. Many of them live for about 1,800 years and grow to a height of 60-80 metres (196-262 feet). The world's most massive trees are the giant redwoods. They are also called Giant Sequoias, California Big Trees etc., they grow to a height of 75 to 80 metres (245-262 feet) with a girth (width) of about 23 metres (75 feet) near the base. |
