CONIFEROUS AND DECIDUOUS FORESTS1) Coniferous and deciduous forests are two of the tree major types of forest. Life in the two areas has developed very differently, due to the differences in climate. 2) Coniferous are so called because their seeds are produced in cones. Vast coniferous forests of spruce, cedar, larch, pine and fir are found where conditions are cold and harsh, with brief summers and low rainfall, i.e. northern parts of America, Europe and Asia and in the worlds mountainous areas. Further south, conifers exist alongside deciduous trees in mixed forests. 3) Most conifers have needles instead of leaves (their smaller surface area means less water is lost by evaporation) and the majority are evergreen (never bare of needles), so they can produce food all year round. 4) The word deciduous describes trees that shed their leaves once a year. They are flowering plants, mainly blooming once a year in the spring. Deciduous forests are found in areas with relatively mild temperatures and plenty of rainfall throughout the year. Most of Europe, Japan, eastern Asia and the eastern USA were once covered in forests of deciduous trees, like oak, beech, maple and ash. 5) Deciduous trees have large, broad leaves to make the most of the many months of sunshine for photosynthesis. They are lost before winter when strong winds and cold would damage them. Each tree provides homes and food for a large wildlife community. Rich soil and plenty of sunshine allow many different plants to flourish. These support still more animal life.
