Makehe forest is a natural virgin forest with biggest source areas, most intensive distribution and highest altitude of the Dadu River in the Yangtze basin. It once supplied 0.68 million m^3 wood for the national economic construction. The logging volume was reduced to zero thanks to the launch of natural forest protect project in 1998. The practical forestry management and protection effectively advances the protection and restoration of natural forest and improves the forest resource and ecological environment. The forest cover increases from 52.6 percent previously to 59 percent and total standing stock volume rises from 3.61 million m^3 to 4.6 million m^3. Furthermore, it helps gain remarkable ecological, social and economic benefits.
