Flora of Pakistan is the assemblage of vascular plants and lower plants occurring within the political boundaries of Pakistan, reflecting intersections of the Himalayas, Karakoram, Hindu Kush, Indus River basin and the Arabian Sea. The flora exhibits strong affinities with the Irano-Turanian flora, Sino-Himalayan flora, and Afro-Malagasy floristic region elements, shaped by glaciation events such as the Pleistocene glaciation and tectonic uplift associated with the Indian Plate–Eurasian Plate collision. Major botanical surveys and monographic works have documented thousands of taxa across provincial and federal territories including Balochistan, Sindh, Punjab and Khyber Pakhtunkhwa.
Pakistan's vegetation zones range from alpine scree and subnival meadows of the Karakoram and Himalayas to temperate coniferous forests of the Hindu Kush and dry subtropical thorn scrub of the Indus River Delta and Thar Desert. Physiographic provinces include the Indo-Gangetic Plain extension, the montane zones (alpine, subalpine, montane) and xeric scrublands influenced by the Arabian Sea and monsoon systems such as the Southwest Monsoon. Elevation gradients support zonation: montane pine and juniper stands, broadleaved temperate forests, montane grasslands, and cold desert floras on the Deosai Plateau. Plant distributions reflect biogeographic corridors connecting to the Tibetan Plateau and Central Asia.
Pakistan hosts a rich vascular flora with estimates exceeding 5,000–6,000 species including representatives of families such as Fabaceae, Asteraceae, Poaceae, Lamiaceae, and Rosaceae. Endemism is concentrated in isolated high-elevation ranges and insular plateaus; endemic taxa occur in the Kirthar Mountains, Sulaiman Range, and Himalayan foothills. Genera with regional radiations include members of Rhododendron in montane woodlands, Berberis shrubs, and alpine herbs related to Central Asian lineages like Saussurea and Potentilla. Floristic affinities link Pakistan with the Mediterranean Basin through Irano-Turanian elements and with Southeast Asia through Sino-Himalayan migrants.
Key plant communities include montane conifer forests dominated by Pinus wallichiana and Cedrus deodara in the western Himalaya; temperate broadleaf woodlands with Quercus baloot and Acer-affiliated species; high-altitude alpine meadows with species of Gentiana, Primula, and Onobrychis; cold deserts supporting Tamarix and Haloxylon halophytes; and saline mangrove stands of Avicennia marina in the Indus River Delta. Riparian belts along the Indus River sustain populations of Salix, Tamarix, and cultivated orchards of Mango and Date palm in irrigated plains. Steppe and thorn scrub communities feature spiny legumes and grasses adapted to seasonal drought.
Plants provide timber, fuelwood, forage, medicinal resources, and cash crops integral to provincial economies such as Punjab and Sindh. Agroforestry and cultivated plants include Wheat, Cotton, Sugarcane, Rice, and orchards of Mango, Citrus and Citrus × sinensis varieties. Ethnobotanical traditions employ taxa like Nigella sativa and Berberis lycium in traditional healing systems linked to communities studied by institutions such as the Pakistan Museum of Natural History and universities like University of Peshawar and Quaid-i-Azam University. Non-timber forest products—resins, gums, and medicinal herbs—are harvested in regions including Gilgit-Baltistan and Balochistan.
Threats to plant diversity arise from habitat conversion for agriculture in the Indus Basin Irrigation System, overgrazing by pastoralists in rangelands of Balochistan and Khyber Pakhtunkhwa, unsustainable logging in montane forests, and invasive species vectors linked to trade routes such as the Khyber Pass. Climate change impacts on glacial-fed hydrology and montane microclimates threaten alpine endemics on massifs like Nanga Parbat and K2. International conservation instruments relevant to Pakistani flora include engagement with initiatives by the IUCN and transboundary programs within the Himalayan Climate Initiative context. Red List assessments have identified locally threatened taxa requiring habitat protection and ex situ propagation.
Systematic botanical work has been undertaken by institutions such as the Pakistan Agricultural Research Council, the Herbarium of the Pakistan Museum of Natural History (ISL), and academic herbaria at University of Karachi, University of the Punjab and Karachi University. Historic collectors and botanists who contributed to regional knowledge include figures associated with expeditions similar in legacy to Joseph Dalton Hooker and surveys akin to the Great Game-era naturalists, while contemporary taxonomists publish in collaborations with international centers like the Royal Botanic Gardens, Kew and the Smithsonian Institution. Molecular phylogenetics, floristic inventories, and conservation botany are active research areas supported by grants from agencies including the Global Environment Facility.
Protected areas conserving plant diversity encompass national parks and reserves such as Kirthar National Park, Hingol National Park, Deosai National Park, and Khunjerab National Park, which protect montane, coastal, and desert floras. Restoration and reforestation programs led by provincial forest departments and NGOs collaborate with international partners like the World Wide Fund for Nature to restore degraded watersheds, combat desertification under frameworks resembling the UN Convention to Combat Desertification, and promote community forestry models in Azad Kashmir and Gilgit-Baltistan. Ex situ conservation initiatives include seed banks and botanical gardens that cooperate with global networks for plant conservation.
