Several controversies on conviction and sentencing standards in wildlife criminal cases was discussed in this article,including ill-defined concept of wildlife and its products,the large difference between two kind of sentencing standard—the number of individual animals and the values of their products,application of protection level and value standard of the species in CITES appendix.These problems mainly result from the mutual non-convergence between the relevant judicial interpretation and the authorities’ value standard of wildlife and its products.For these questions,some specific adjustment measures were presented,such as clearly defining the scope and value standard between wildlife itself and its products,adjusting the standard of individuals number according to the value of wildlife,clearly declaring the appliance of different protection levels,and define the value standard of species in CITES appendix etc.
