The increasing anthropogenic pressure especially increasing influx of tourists at health resorts in mountainous regions decreases the distribution of trees in the given area, which ultimately affects the variety, variability, uniqueness and distribution pattern in Forest Ecosystem. The area belongs to temperate region of Pir Panjal mountain range. In order to cope up with this situation a phyto-sociological study was carried out during the month of May to December 2010. The main objective of the study was to determine the distribution pattern of tress and impact of tourist on forest ecosystem. The study was based on three sites with marked differences in their physical and biotic features. The composition and the number of tree species were recorded by quadrat method. Quadrates of size (10m__ampersandsigntimes;10m) were randomly laid. During the study period, the only tree family observed was Pinaceae. The total IVI was observed highest (135.7) for Abies pindrow at site3 and lowest (74.7) total IVI was observed for Pinus wallichiana at site1. The total relative density was observed highest (51.1) for Abies pindrow at site3 and lowest (21.2) was observed for Pinus wallichiana at site1. Shannon Weiner diversity Index having small variation during the study period. Dominance index (Simpson Index) was less than 1 which showed that the sites were not dominated by single species. The distribution pattern of trees was random. The primary conclusion is, there is a moderate anthropogenic impact on normal distribution of tree community which may cause decrease in tree line within next few decades in the forest ecosystem.
