Fixing rotation of maximum value production for Chir pine (Pinus roxburghii) forests of Murree

ABSTRACT
Tree species in a forest exhibit different patterns of growth. Some species may show rapid growth in early life but slow down later while others may follow a reverse pattern. Besides intrinsic growth character of the species, soil, geology, gradient, micro-climate etc. and management practices applied to the forest are some of the factors which influence the growth design. Different species thus depict different pattern of growth during their life cycle and as such would need different management approaches and decisions including the fixation of rotation age. Fixation of the felling age of a tree species is primarily a managerial decision depending upon the evaluation of several criteria and options consistent with the prevalent policy. Thus for some species there could be different ages (rotations) at which trees may be felled for specific management objective.
