Himalayan Moist Temprate Forests Of Pakistan - Forests Types Of Pakistan

#NIB Himalayan moist temperate forests: The evergreen forests of conifers, locally with some admixture of oak and deciduous broad-leaved trees fall in this category. Their undergrowth is rarely dense, and consists of both evergreen and deciduous species. These forests occur between 1500 m and 3000 m elevation in the Western Himalayas except where the rainfall falls below about 1000 mm in the inner ranges, especially in the extreme north-west. These forests are divided into a lower and an upper zone, in each of which definite species of conifers and/or oaks dominate. In the lower zone, Cedrus deodara (Deodar, diar), Pinus wallichiana, Picea smithiana and Abies pindrow (Partal) are the main conifer species in order of increasing altitude, with Quercus incana (rin, rinj) at lower altitudes and Q. dilatata above 2130 m. In the upper zone Abies pindrow and Q. semecarpifolia are the dominant tree species. There may be pockets of deciduous broad-leaved trees, mainly edaphically conditioned, in both the zones. Alder (Alnus species) colonizes new gravels and sometimes kail does the same. Degradation forms take the shape of scrub growth and in the higher reaches, parklands and pastures are subjected to heavy grazing.
