beech marten (Martes foina), the brown bear (Ursos arctos), the Asian black bear (Selenarctos thibetanus), the Turkestan lynx (Lynx lynx isabellinus), the red fox (Vulpes vulpes) and the Tibetan wolf (Canis lupus filchneri). The number of bird species present is low. The robin accentor (Prunella rubeuloides) and black-throated thrush (Turdus ruficollis) overwinter here, and vultures, birds of prey, rosefinches (Carpodacus spp.), Himalayan monals (Lophophorus impejanus) and Güldenstädt's redstarts (Phoenicurus erythrogaster) remain throughout the year, though they may move to somewhat lower elevations in winter. There are three species of lizard in the park but no amphibians. Climbing Expeditions come each year to this area of the Karakorum to ascend the massive peaks, climb rocky crags and big sheer rock walls, and trek. Most expeditions visit the region in July and August, but some come as early as May and June, and September can be good for lower altitude climbing. One celebrated climbing area is Trango Towers, a group of some of the world tallest rock towers, situated in the park close to the route used to trek to the K2 base camp. Every year, a number of expeditions from all parts of the world visit the area to climb these most challenging granite towers. References National parks of Pakistan Protected areas of Gilgit-Baltistan
