Flora of Pakistan - Distribution

Distribution

Northern highlands and valleys

Pakistan has conifer forests in most of the northern and north-western highlands. These occur from 1,000 to 4,000 m altitudes. Swat, Upper Dir, Lower Dir, Malakand, Mansehra and Abbottabad districts of Khyber Pakhtunkhwa (formerly North-West Frontier Province) are the main areas covered with coniferous forests. Silver fir (Abies alba) and 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.

Western highlands, plains and deserts

In north of Balochistan, conifer forests of juniper (Juniperous macropoda) are found, such as in Quetta and Ziarat. Near Sulaiman Mountains, chilghoza pine (Pinus gerardiana) forests are also present. In the xeric regions of Balochistan (such as in Kharan desert), date palms and ephedra are common flora varieties.

Eastern plains and deserts

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 riparain woodlands grow in narrow belts along the banks of River Indus and its tributaries. Main tree varieties are of sheesham and babul and main shrub varieties are reed beds and tamarisk (Tamarax dioica) bushes.

Wetlands and coastal regions

In the south of Sindh are Indus River Delta in west and Great Rann of Kutch in east. The largest saltwater wetland in Pakistan is the Indus River Delta. Unlike many other river deltas, it consists of clay soil and is very swampy. 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. Other saltwater wetlands are located on the coast of Balochistan such as at Sonmiani and Jiwani. These and Indus River Delta support mangrove forestry, mainly of species Avicennia marina.

Famous quotes containing the word distribution:

    The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.
    George Bernard Shaw (1856–1950)

    Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.
    Cyril Connolly (1903–1974)

    My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.
    Rutherford Birchard Hayes (1822–1893)
