Pakistan is a country in South Asia. It is the world's fifth-most populous country, with a population of almost 227 million. Pakistan is the 33rd-largest country by area, spanning 881,913 square kilometres, It has a 1,046-kilometre coastline along the Arabian Sea and Gulf of Oman in the south, and is bordered by India to the east, Afghanistan to the west, Iran to the southwest, and China to the northeast. It is separated narrowly from Tajikistan by Afghanistan's Wakhan Corridor in the north, and also shares a maritime border with Oman.
The diversity of the landscape and climate in Pakistan allows a wide variety of trees and plants to flourish. The forests range from coniferous alpine and subalpine trees such as spruce, pine, and deodar cedar in the extreme northern mountains to deciduous trees in most of the country, to palms such as coconut and date in the southern Punjab, southern Balochistan, and all of Sindh. The western hills are home to juniper, tamarisk, coarse grasses, and scrub plants. Mangrove forests form much of the coastal wetlands along the coast in the south.
Coniferous forests are found at altitudes ranging from 1,000 to 4,000 metres in most of the northern and northwestern highlands. In the xeric regions of Balochistan, date palm and Ephedra are common. In most of the Punjab and Sindh, the Indus plains support tropical and subtropical dry and moist broadleaf forest as well as tropical and xeric shrublands. These forests are mostly of mulberry, acacia, and eucalyptus. About 2.2% or 1,687,000 hectares of Pakistan was forested in 2010.
The fauna of Pakistan also reflects the country's varied climate. Around 668 bird species are found there, including crows, sparrows, mynas, hawks, falcons, and eagles. Palas, Kohistan, has a significant population of western tragopan. Many birds sighted in Pakistan are migratory, coming from Europe, Central Asia, and India.
The southern plains are home to mongooses, small Indian civet, hares, the Asiatic jackal, the Indian pangolin, the jungle cat, and the desert cat. There are mugger crocodiles in the Indus, and wild boar, deer, porcupines, and small rodents in the surrounding areas. The sandy scrublands of central Pakistan are home to Asiatic jackals, striped hyenas, wildcats, and leopards. The lack of vegetative cover, the severe climate, and the impact of grazing on the deserts have left wild animals in a precarious position. The chinkara is the only animal that can still be found in significant numbers in Cholistan. A small number of nilgai are found along the Pakistan–India border and in some parts of Cholistan. A wide variety of animals live in the mountainous north, including the Marco Polo sheep, the urial, the markhor goat, the ibex goat, the Asian black bear, and the Himalayan brown bear. Among the rare animals found in the area are the snow leopard and the blind Indus river dolphin, of which there are believed to be about 1,100 remaining, protected at the Indus River Dolphin Reserve in Sindh. In total, 174 mammals, 177 reptiles, 22 amphibians, 198 freshwater fish species and 5,000 species of invertebrates have been recorded in Pakistan.
The flora and fauna of Pakistan suffer from a number of problems. Pakistan has the second-highest rate of deforestation in the world, which, along with hunting and pollution, has had adverse effects on the ecosystem. It had a 2019 Forest Landscape Integrity Index mean score of 7.42/10, ranking it 41st globally out of 172 countries. The government has established a large number of protected areas, wildlife sanctuaries, and game reserves to address these issues.
