I'm sorry, as an AI language model, I don't have access to real-time data or specific information about licensing fees in Rwanda. The cost of obtaining a license for harvesting a state forest would depend on various factors such as the size of the forest, the number of trees to be harvested, the type of trees, and the current regulations and policies in place. It's best to contact the relevant government department or forestry agency in Rwanda to get accurate information regarding the specific fees and requirements for obtaining such a license.
