International Pakistan's native flora reflects its varied climatic zones, which range from arid and semi-arid to temperate and tropical.
Pindrow fir (Abies pindrow) and Morinda spruce (Picea smithiana) occupy the highest altitudes, deodar (Cedrus deodara) and blue pine (Pinus wallichiana), the intermediate heights, and chir pine (Pinus roxburghii), occupy the lower areas.
In most of Punjab and Sindh, the Indus plains have many fluvial landforms that support various natural biomes including tropical and subtropical dry and moist broadleaf forestry as well as tropical and xeric shrublands (deserts of Thal in Punjab, Tharparkar in Sindh) and kair (Capparis aphylla) which provide firewood.
The Great Rann of Kutch below the Thar Desert is not as swampy and exhibits shrubland vegetation of rather dry thorny shrubs as well as marsh grasses of Apluda and Cenchrus.
These and Indus River Delta support mangrove forestry, mainly of species Avicennia marina.
