History of Forest Management in Pakistan-II, Temperate Coniferous Forests
Ghaus Mohammad Khattak
ABSTRACT
The temperate coniferous forests Pakistan and Azad Kashmir have all along been mostly worked under the selection system since their management was initiated in 1900. The uniform system was briefly tried in Galis (1924 to 1939) and Upper Siran (1927 to 1954) but could not be made to work under the conditions then prevailing. Currently all these forests are being worked under the selection system as applied to Pakistan (Champion, Seth and Khattak, 1965). Yield has been prescribed in a variety of ways: (1) by number of trees = total number o f exploitable trees divided by assumed time of passage from the class next below the exploitable, to the exploitable size. (2) by volume = volume of exploitable trees divided by assumed time of passage from the class next below the exploitable, to the exploitable size. (3) by an arbitrary percentage of the volume of enumerated growing stock -most commonly varying from .5 to .7%
