Abstract
The study was carried out to describe the pine communities at Indus Kohistan valley in quantitative term. Thirty stands of relatively undisturbed vegetation were selected for sampling. Quantitative sampling was carried out by Point Centered Quarter (PCQ) method. Seven tree species were common in the Indus Kohistan valley. Cedrus deodara was recorded from twenty eight different locations and exhibited the highest mean importance value while Pinus wallichiana was recorded from 23 different locations and exhibited second highest mean importance value. Third most occurring species was Abies pindrow that attained the third highest mean importance value and Picea smithiana was recorded from eight different locations and attained fourth highest importance value while it was first dominant in one stand and second dominant in four stands. Pinus gerardiana, Quercus baloot and Taxus fuana were the rare species in this area, these species attained low mean importance value. Six communities and four monospecific stands of Cedrus deodara were recognized. Cedrus-Pinus community was the most occurring community, which was recorded from 13 different stands. The second most occurring community in the study area was Abies –Pinus wallichiana which was recorded from six locations while Cedrus-Picea and Abies-Picea communities were observed at two locations each. Pinus wallichiana - Picea and Cedrus-Pinus gerardiana communities were restricted to one location.
