IntroductionFrom the past till now. The Government has recognized the importance of forest restoration is very much by policy refreshing forest reached the targets, 40 per cent of the area of the country. Degraded areas, rehabilitation is complete the original forest is difficult to achieve in a short time. In particular, economic forest zones which may include both the original forest area and forest area in traditional agricultural areas are somewhat degraded forests have little economic value, because a logger utilized without management t.Tree planting projects, as well as a good substitute for most of the past will be planting a few types of wood or wood-native rapidly come to grow, but when considered in the original forest ecosystem. The complex forest structure and diversity of wild plants found such substitution cannot recover back all but only some (NAT tantayaporn, 2557 (2014)) To preserve the country's forest ecosystems provide are manifold, that is very important to the development of countries in the future. Forest rehabilitation from multiple units. Make the importance of forest resources in several agencies, but a success from a tree planting in the past that are not worth the money that is lost because of several reasons, such as lack of dulaekla wood in an initial stage to make seedlings survival rate low, or to grow in areas where wood is not the origin causes poor growth, leave the plant growth and development as a substitute in accordance with nature. It is refreshing and good. Study on the characteristics of forest areas through society, plant regeneration, thus making the way to revitalize an area degraded back to the wild. The condition of the forest research station of agriculture Trad loop after planting renewable concession on all types of wood found that planting more and more local wood, natural wood, but there is a lot of value to the wood up relatively little substitution (NAT tantayaporn and faculty, 2555 (2012)) therefore, in order to revive the forest so that it can return with good condition. The output and quality of forests is better, so it is necessary to know the type of wood and the distribution of important information that is used to define which types of wood and design appropriate management. Study on the characteristics of dry forest plants through social rehabilitation, with important information to use in improving the structure of forest and jungle, male enhancement, and can be used to guide the Administration to apply with geography. A similar climate to be useful in increasing forest and an abundance of Woods in this event to provide a variety of types of trees fallen and rolled on the ground in the dry forest to wood. To be used as guidelines in appropriate forest management.
