In overall botanical importance to human existence, only food plants rank above wood and wood products. In early human history wood had been of greater importance than the food plants, as a fuel and for weapons and tools. There are over 4500 products that come wholly or in part from the wood of forest trees. Wood is used for housing, furniture, fuel, paper, charcoal and distillation by products, and synthetic materials such as rayon, cellophane and acetate plastics. One of the most obvious uses for trees is the production of building and furniture. Many millions of board feet of certain softwoods are used each year for home construction. Because of the grains, colors and durability of hardwoods, they are most often used in furniture making. Now a day is introduced in house construction like concrete roofs, iron doors and windows but plants still play very important in the construction of homes. The most preferred species used for the said purpose are Acacia spp, Pinus rox-burghii, Myrsine africana, Dodonaea viscosa, Dalbergia sissoo, Olea ferruginea, Morus alba, M. nigra, Celtis caucasica, Psiticia integrrima, Segeretia brandrethina and Quercus spp. Leaves, branches and poles of these species are used, as most of the local houses have mud roofs. Pinus spp., Morus spp. Quercus spp., Melia aza-darach and Olea ferruginea wood is also sold in the local markets as timber.
