Abstract: The Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Law in the Trial of Criminal Cases of Destruction of Forest Resources has come into effect since the first National Ecological Day (August 15, 2023). This explanation has redefined the behavior and criteria for the crime of illegal logging of trees, added conversion rules and value standards for the volume of standing trees and the number of young trees, and clarified the nature of dead trees. However, there is still significant controversy over whether the crime of illegal logging belongs to the offence to intent, the standard of achievement, whether the illegal logging behavior includes "illegal excavation", and the relationship between larceny and the crime of illegal logging of trees. It should be clarified that the crime of illegal logging is not aimed at "illegal possession". From the perspective of legal interests, the standard of achievement for the crime of illegal logging should be grasped. It should be clarified that illegal logging behavior should include "illegal excavation", and the imaginative competition relationship between the crime of illegal logging and larceny should be correctly understood, in order to further improve the judicial application of the crime of illegal logging.
