Pattern of Coupes in Selection Forests

In November 1955 and August 1956 (Indian Forester) the author had given five formulae for calculation of yield, working capital, felling cycle, etc., for forests worked under selection system. They were applicable to forests when they were worked for one or two felling cycles and the distribution of selection trees per acre was much more in the earlier coupes than in the later ones. In this paper formulae have been constructed for forests where all the trees are distributed equally over the whole area as is the condition. Over a virgin forest wherever the previous formulae have been used for such forests, they will be replaced by the new ones. In addition some important conclusions which are summarized at the end of this paper have been reached.
