Forests are the major biological land resources of the globe.
Research on sustainable forest management, wise use of forest resources and reforestation is now receiving more widespread concern than at any time in history. Research efforts and results of forest science have been accumulated by the Department of Forest Science, including studies on the many effects on the forest, such as wood and timber production, soil and water conservation, protection of wildlife and recreation. Besides the effects on the forest, the need for a comprehensive approach on forest land management has been recognized recently, and the target area of forest science is extended to include whole watersheds and urban areas. Research on conservation and utilization of forest and forest resources are being developed. Global environmental issues such as global warming, acid rain and degradation of tropical rainforests, are also important subjects of forest science.
