FOREST TYPES OF PAKISTAN PAKISTAN
The total area of forests in Pakistan is 4.224 million ha which is 4.8% of the total land area. However, it may be mentioned here that the farmland trees and linear planting along roadsides, canal sides and railway sides covering an estimated area of 466,000 ha and 16,000 ha respectively do not constitute forests within the context of legal, ecological or silvicultural silvicultural/managem /management ent definition of forests. forests. The situation situation is also similar, similar, but to a lesser extent, in the case of miscellaneous plantations over an area of 155,000 ha. If the area of these three categories of plantations is excluded from total forest area of 4.224 million ha, then the latter is reduced to 3.587 million ha which is approximately 4.1 % of the total area. As recognition of the multiple values of forests has grown, so have concerns for their disappearance. In Pakistan, subtropical, temperate, riverain and mangrove forests are being lost because of questionable land use practices and the ever-increasing demand for timber and firewood. As a result, more responsible management approaches are being demanded that can accommodate complex economic and ecological needs. Designation of selected forest forestland landss as national national parks, parks, area area for agro-fo agro-fores restry try practic practices es and the developm development ent of plantations plantations and a forest forestation ation practices practices are are needs of the hour. hour. Total Forest Area under the control of the Forest Departments (including Azad Kashmir and the Northern Areas) is 4.26 million hectares. The per capita forest area is only 0.037 ha compared to the world average of ONE ha. Main reason for this is that more than 70% land area of Pakistan is Arid and semi-Arid with annual rainfall of 250-500 mm: too low and erratic to sustain natural vegetation and to plan a forestation/regeneration programmer.

The world world Littor Littoral al and Swamp Swamp forest forestss cover cover at least least 14 millio millions ns hectors hectors and 257500 257500 hectors of these are found in Pakistan which is 7 th largest Littoral and Swamp forests in world. world.
Forest Forest is evergreen. evergreen. The root produce produce aerial outgrowt outgrowths hs from the soil which
protrude from the wet ground like fingers; fingers; these are called pneumatophores. pneumatophores. The seed germinate on the mother plant before shedding and fall on wet ground in the form of small seedling. This phenomenon is called vivipary. This forest is not important from the point of view of timber production. Mangrove forests are teem teeming ing with with life life..

Mangrove areas act as physical breeding grounds and nurseries nurseries for fish, shrimp shrimp and crabs.

In upper Indus plains these forests are known as Rakh forest while in lower Indus plains as Desert forests. In open low forests in which thorny usually hard wood species predominant. These trees have short bole and low branching crowns. Regeneration occurs by root sucker. They are primarily used as firewood.

(3) Tropical dry deciduous forests These are forests of low or moderate height consisting almost entirely of deciduous species. Their canopy is typically light though it may appear fairly dense and complete during the short rainy season.
DISTRIBUTION: This type does not occur extensively in Pakistan but there are limited areas in the Rawalpindi foothills carrying this vegetation type, all much adversely affected by close proximity to habitation or cultivation. The forests occur at elevation 1200-2000 ft.
LOCALITY FACTORS: The spring is hot and dry but there is much rain in late summer up to 37 inches in the year.
