The percentage of Pakistan's area that is forest is disputed. The UN's Food and Agriculture Organisation estimates 2.2% of the total land of Pakistan is covered by forests. On the contrary, Pakistan Forest Institute estimates it to be 5.1%. According to the survey done under the Red Plus programme in 2017, the forest cover of Pakistan is 5.7%.
According to survey under Red Plus programme, the Azad Jammu and Kashmir has the highest forest cover at 36.9%, followed by Khyber Pakhtunkhwa (20.3%), Islamabad (22.6%) and Federally Administered Tribal Areas (19.5%). The World Wild Fund report that between 2000 and 2010 Pakistan has lost 43,000 hectares of land every year.[2]
The tropical thorn forests are dominated by xerophytic shrubs. They are most widespread in the Punjab plains but also occupy small areas in southern Sindh and western Balochistan. They are mainly used for grazing purposes, watershed protection and fuelwood. Common species are vann (Salvadora oleoides), khejri (Prosopis cineraria), kair (Capparis aphylla), etc.
The irrigated plantations were first developed in 1866 at Changa Manga in Lahore. Today they occupy about 226,000 ha. Sheesham (Dalbergia sissoo), mulberry/Shahtoot (Morus alba), babul (Acacia nilotica) and species of Eucalyptus and Populus are the common tree species grown in the irrigated plantations.
The riparian forests grow in narrow belts along the banks of River Indus and its tributaries. They are more commonly found in Sindh and to some extent in the Punjab. Babul (Acacia nilotica), Shisham (Dalbergia sissoo) and Tamarax dioica are the most common species. Khejri (Prosopis cineraria) and Populus euphratica are some other species. They are mainly used for lumber.
The forests of Pakistan are a main source of lumber, paper, fuelwood, latex, medicine as well as human and animal food. Other minor products include resin (a fluid in tissue of Chir pine plant that becomes solid on exposure to the air) and 'mazri' (used for making baskets). The forests also provide for ecotourism and wildlife conservation purposes. Forests have also been planted in some areas like Thal Desert to avoid soil erosion and further desertification. Riparian zone along the river Indus have been managed to avoid excess flooding.
According to the UN in 2011, Pakistan was the most heavily deforested country in Asia.[3] The Federal Bureau of Statistics provisionally valued the deforestation sector at Rs.25,637 million in 2005, thus registering over 3% decline of forests in Pakistan since 2000.[4] The main reasons of deforestation are urbanization, farming, overgrazing, and tourism development. Wildlife in Pakistan is confronting a critical situation, marked by the dwindling populations of numerous species. This decline is primarily attributed to pressing threats, including illegal wildlife trade, habitat loss due to urbanization, rising pollution levels, and the impacts of climate change.[5][6]
This has led to severe consequences such as desertification, flooding and endangering of wildlife. As a consequence to deforestation and changing land use patterns, the most critically affected ecosystems of Pakistan are:
Juniper forests of northern Baluchistan have been heavily harvested for timber and fuel wood.
Ecological changes in the Indus River riparian zone have drastically affected the riverine forests. Large tracts have been cleared for agriculture.
The Himalayan temperate forests are also under severe pressure from logging for timber and firewood, and from clearings for agriculture and human settlements. Deforestation rate in Pakistan is increasing 0.2 to 0.5 percent annually.
The protected areas serve the purpose of conserving the forests and wildlife of Pakistan. National Conservation Strategy of 1993 was a major landmark of start of conservation of natural resources and wildlife in Pakistan. Resource-managed man-made forests like Changa Manga, Kamalia plantation and Chichawatni plantation have also been planted to serve purpose and conserve forests. Through conservation, a large region of Thal desert has been afforested.
