The study was conducted to compare the present growing stock of sub-tropicalpine forests of Murree hills in Pakistan with the standard values of growing stockof a Normal Forest. Stand table was prepared for the major timber species of thearea (Pinus roxburghii Sargent) using fixed area plot method of sampling in entirearea of 4323 hectares. Comparison was made on the basis of the values for each treediameter class given by Ahmed and Bashir (1959). The study revealed that in sub-tropical pine forest of Ghoragali, pole crop (24-36 cm diameter) is in excess numberand very few are present in mature ages (132-150cm diameter class). This meansthat growing stock of Ghoragali forest is quite deviated from the normal values indifferent diameter classes probably because of poor implementation of previousmanagement plans and also due to mismanagement resulting from the ban on "GreenFelling" imposed by the government earlier.
