There is a variety of forest management institutions ranging from state management to community and private management. This article attempts to identify the conditions under which one institution outperforms the others in the efficiency of forest management based on a review of the literature, empirical evidence on the dominant forest management institutions, and theoretical arguments. In conclusion, we argue that the community management system performs best for non-timber forests, whereas a mixed management system, in which forest protection is carried out communally and tree management is carried out individually, is likely to work best for timber forests.
