Distribution Characteristics of the Tree Species in Central Himalaya, India

A total of 257 tree species were recorded and studied for their pattern and altitudinal distribution in Central Himalaya. Relatively higher percentage (65%) of deciduous species was recorded. Distribution of tree species in this region is between <200-4200 m asl. However, maximum (60%) species were found either below or at around 1500 m asl altitudes may be due to overlapping of species. Lauraceae and Anacardiaceae are the dominant families in both forms. Species richness declines gradually towards the higher altitudes, it was sharper in evergreen species. Study concludes, the distribution of trees in central Himalaya, depends upon climate, soil, temperature and altitude.
