Legal basis: the State Council City, China issued "Natural Forest Protection and Restoration Project Plan (VII)" to establish a natural forest recuperation system. Stop the commercial logging of natural forests completely. For natural forests listed in key protected areas, all other production and business activities are prohibited except taking necessary measures to maintain the health of natural forest ecosystems such as forest pest control and forest fire prevention. To carry out natural forest tending, an operation design must be prepared and implemented after examination and approval by the competent forestry department. Relying on the construction of national reserve forest base, cultivate large-diameter timber and precious tree species, and safeguard national timber safety.
