The damage caused by forestry pests to forest plants has become a constraint to China's forestry construction, improvement of ecological environment and sustainable economic development.
A serious disaster in the exhibition. Therefore, we will formulate disaster standards for forestry pests in China, and comprehensively, objectively and scientifically reflect and evaluate China's forests.
The disasters caused by pests on forest plants are of great significance for the monitoring and early warning of forestry pests and for disaster prevention and reduction.
This standard is proposed and managed by the Forestry Department of the State Forestry Administration.
