A Theory of Red Pine (Pinus Koraiensis) Management for Both Timber and Commercial Seeds

摘要

Red pine (Pinus koraiensis), is a commonly distributed species of tree in northeastern China. The wood is used for manufacturing purposes as usual, and the seeds are used as a source Of delicious food and for medical applications. Lf the top of the tree is removed at a mature age, seed Production is much enhanced. In this article, we derive optimal harvesting rules for such multiple use Management of red pine trees. In this article, we derive optimal harvesting rules for succh multiple use Intensity of removal, and the optimal date for the final felling.
