Plant and animal life
Differences of latitude, elevation, soil type, and climate have favoured a variety of plant growth. Drought-resistant vegetation in the desert consists of stunted thorny scrub, mostly acacia. The plains present a parkland view of scattered trees. Dry scrub forests, called rakhs, grow in parts of the arid plain. In the northern and northwestern foothills and plains, shrub forests, principally acacia, and wild olive are found. In the wetter parts of the northern and northwestern mountains, evergreen coniferous softwood forests, with some broad-leaved species, grow. Fir, deodar, blue pine (Pinus wallichiana), and spruce are the principal coniferous trees. At lower elevations, below 3,000 feet (900 metres), broad-leaved oaks, maples, birches, walnuts, and chestnuts predominate. Conifers are an important source of commercial timber. In the arid landscape of the Potwar Plateau, some hills are only thinly wooded. In the northern ranges of the Balochistan plateau are some groves of pine and olive. The babul tree (Acacia arabica) is common in the Indus River valley, as are many species of fruit trees. The country’s forest cover is naturally sparse, but it has been diminished further by excessive timber cutting and overgrazing.
Destruction of natural habitats and excessive hunting have led to a reduction in the range of animal life in large parts of the country, but wildlife can still be found in abundance in some areas. The variety of large mammals in the northern mountains includes brown bears, Asiatic black bears (Ursus thibetanus, also known as the Himalayan bear), leopards, rare snow leopards, Siberian ibex (Capra ibex sibirica), and wild sheep, including markhors, Marco Polo sheep (Ovis ammon polii, a type of argali), and Chiltan wild goats (Capra aegagrus chialtanensis).
Manchhar Lake in Sindh has many aquatic birds, including mallards, teals, shovelers, spoonbills, geese, pochards, and wood ducks. Crocodiles, gavials (crocodile-like reptiles), pythons, and wild boars inhabit the Indus River delta area. The Indus River itself is home to the Indus river dolphin, a freshwater dolphin whose habitat has been severely stressed by hunting, pollution, and the creation of dams and barrages. At least two types of sea turtles, the green and olive ridley, nest on the Makran coast.
Desert gazelles are widely distributed, including nilgais, chinkaras (Gazella gazella bennetti), and muntjacs. Jackals, foxes, and various wild cats (including Eurasian lynxes, caracals, fishing cats, and jungle cats [Felis chaus]) are also found throughout the country. Despite occasional reported sightings of the Asiatic cheetah, that species is likely extinct in Pakistan. A series of national parks and game preserves was established beginning in the 1970s. However, a number of species have been declared endangered, including the Indus river dolphin, snow leopard, and gavial.
