NATURAL VEGETATION
Forest
A large area of land covered with trees and under growth either naturally or artificially.
Trees are most important to human because they supply timber and fire wood. They
also help to reduce surface runoff, soil erosion and air pollution.
Infect it is claimed that 20 – 25 % of a country should be covered by forests in order to
maintain a balanced economy. So trees must be planted extensively and promoted
widely for future generation.
In Pakistan only about 4.8 % of total area is forested which is very less. Every year we
import large quantity of wood from other countries of the world. In 1947 forest covered
only 1.7 % of total land area. So the increase in forest area was achieved by reforestation
(re-afforestation) or regeneration programmes.
The arid conditions and reckless cutting of the trees account for the low percentage of
forest covered areas in Pakistan.
Forestation
Forestation is the planting of new forest on a new location. This process is done with
careful planning. The selection of plant species depends upon the type of soil, climatic
condition and availability of water.
Reforestation
Reforestation is the planting of a forest in an area where deforestation was done.

Types of Forest
There are two types of forest:
1. Productive Forests
2. Protection Forests
1. Productive Forest (Production Forest)
Production forests are those forests which are exclusively grown for production of fruits
and medicinal purposes.
One third of forest area in Pakistan is covered by productive forests. These forests have
great commercial value because they are mainly used for the extraction of timber and
other products.
2. Protection Forest
Protection forests are those forest which either exists naturally or grown in particular
area for the protection of environment.
These forests cover two third area and planted along roads, railway track and in parks.
The main function is to protect the soil from erosion and to keep the environment
pleasant by lowering the temperature and providing shade.
Importance of Forest /Advantages
1. Forest prevent soil erosion.
2. Forests regulate water supply in river to prevent floods.
3. Forests check the pollution and provide clean environment.
4. Forests provide raw material for wood based industries.
5. Forests provide employment opportunities in the forest department..
6. Some plants are used for medicinal purposes.
7. Forests provide recreational facilities and develop tourism.
8. Forest provide natural habitat for wild life.
9. Forest provide oxygen and absorb carbon dioxide.
10. Forest provide shade and fruits.
11. Leaves and branches intercept the rainfall.
12. Leaves fall, decompose and mix with the soil.
Determinants
There are number of factors that determine the type and density of forests.
1. Areas with different altitude have different types of forests.
2. The arid and semi arid conditions prevailing over the Balochistan Plateau and the
southern part of the Indus Plain is not favorable to support plant growth and results
in thorny bushes and scrub.
3. Higher precipitation in the northern mountains encourages the growth of trees.
4. In Indus and Hub deltas the deposition of alluvium in the salt water has
encouraged
the growth of mangrove vegetation.
5. The diversity of topography (type of soil) also determine the type and density of
forests in different areas of Pakistan.
Tree Line:- The altitude above which no trees grow on a mountain. (below 4500
m)
Snow Line:- The altitude above which snow never melts. (above 4500 m)

Balochistan Plateau.
2. The humid conditions prevailing over parts of the northern hills and mountains.
3. The diversity of topography, ranging from low plains to lofty mountains.
Alpine Forest
Alpine forest are found at an altitude of 4000 meters, alpine forests are found in the
districts of (Distribution) Chitral, Dir, Swat, Shangla, Kohistan and the northern
areas. Long severe winters and frequent freezing temperature prevent trees from
attaining their full height. The dwarfed and stunted growth of (Species) silver fir,
juniper and birch takes place in sheltered nooks. Often, the trees are prostrate. As the
mountains rise to the height of the treeline, they become craggy and steep and there is
limited area for tree growth. In such a severe climate and difficult topography, alpine
forests are found in a limited area. They are not of much economic importance.

Sub Tropical Dry Forest or Scrub Forest
These forests are located up to a height of 1000 meter.These forests are found on the
hills and foothills of Gujrat, Jhelum, Rawalpindi and Attock districts in Punjab and
the Mansehra, Abbotabad, Mardan, Peshawar and Kohat districts in NWFP and
are covered with dry, evergreen forests. In Balochistan, vegetation in the form of
scattered patches of dry mixed scrub, is confined to the Sulaiman Mountains and other
hilly areas.
Over grazing and heavy firewood cutting, bad agricultural practices, urbanization and
lopping had badly affected the original vegetation. Due to shortage of vegetational
cover, the area is suffering from excessive rate of soil erosion. The open areas are
covered with grass and are useful for grazing. The dominant trees in this region are
Phula and Kao. Among the deciduous trees found in this region are the Chestnut,
Juniper, Walnut and Oak.
Features or Characteristics

Irrigated Forest
These forests are man made and are planted under the supervision of Government
especially Forest Department. First irrigated forest was planted in 1866 at Changa
Manga. The main purpose was to supply wood for railway engines. Some other
irrigated forests have been planted in various parts of the country. e.g.
Chichawatni. Sahiwal. Thal. Gudu Barrage. Kotri Barrage. Khanewal. Shorekot.
Bahawalpur and Sukkur Barrage.
After the partition the government of Pakistan has taken special interest for the
extension of these forests. But there was a problem for the extension of these forests,
that was shortage of water especially between November to March.

Tropical Thorn or Rakh Forest
Tropical thorn forests are open, low forests dominated by thorny hardwood trees. In
Punjab, especially in the plains, they are characterized by scrub called Rakh which can
survive on very small amounts of water. They are also found in Sindh, with scattered
patches in southern and western Balochistan. In general, the scrubs are 6 to 10 meters
high. Common species include acacia, tamarisk and salvadora. They are primarily used
as firewood.

2. Their height is 6 to 10 meters.
3. They can survive in small amount of water.
Importance

Timber
Riverain or Bela Forest
These forests are located along the banks of river Indus and its tributaries. Mostly
forests are found in Sindh Province and cover the active flood plain. Important species
are Babul and Shisham. These are hard wood trees.
Fig.5, a map showing the Bela Forest.
Fig.5
Mangrove Forest
These forests are found in Indus Delta, Hub delta and its adjoining areas.
These forests can survive easily in salty water, trees are stunted and only a limited
number of species grow, due to dumping of industrial, agricultural and chemical waste
into the Arabian sea. Important species like Timar, Kirani and Kuni. The general
height is about three to four meters. These are called low trees. These forests are good
breeding place for fish and shrimps and protect the fish from big waves. The roots of
these trees protect the young fish from the predators.

Soil Erosion
It is defined as the wearing away of topsoil by natural agents i.e. wind, water, rain and
glacier. Topsoil is the top layer of soil and is the most fertile because it contains the
most organic, nutrient-rich materials.
Causes of Soil Erosion
Erosion by natural agents i.e. wind, river, rain and glacier
Deforestation by humans
Over grazing by livestock
During mining
Effects of soil erosion
Loss of fertile soil and nutrients
Output reduced
Income of the farmer reduced
Eroded material deposited in dams, reduce the storing capacity of water
Less generation of power
Cause flooding.
Types (Erosion )
1. Sheet / surface Erosion
This occurs when rain falls on bare soil, loosening fine particles (silt, clay and humus)
that are carried downhill in surface run-off.
2. Rill Erosion
It is the removal of soil by concentrated water running through little streams.
3. Wind Erosion
The removel of topsoil by wind. It occurs mostly in flat, bare areas; dry, sandy soils;
or anywhere the soil is loose.
4. Gully Erosion
It is the removal of soil along drainage lines by surface water runoff.
