Seven compartments ( 390 hectares) of varying density, varying slope and species composition of Kaghan Reserved Forests were sampled by B.A. F. 20 prism. Conclusions are drawn that the prism sampling estimates for basal area and volume ( both compartmentwise and for total area) are of acceptable accuracy. A deviation of 20% ( Plus or minus ) may be permitted in prescribed yield for working plans of such areas. The deviations of prism sampling from total enumeration for number of trees (compartinentwise as well as combined stand tables) are unduly large in most of the cases. Because of saving in time and cost, and fair accuracy for volume estimation, the method may be used in preference to 100% enumerations. Till the method is improved further, stand tables prepared with it can only be considered as approximate.
