cultural land every year the growers encroach the
forest land as much as possible and includ them in
their agricultural land. During the working period
they usually walk through the forest with their cattle
and children and exert some indirect pressure on the
forest vegetation. As a result the whole forest area
remains under much disturbance by the growers.
4 GRAZING
Grazing is another severe problem in the forest area.
The people living in the forest area maintain herd of
buffalo, cow, goat and sheep for agricultural purpose.
The cow and the buffalow are used for ploughing. The
peasants also get meat, milk wool and manure from
these animals. Therefore they are the domestic animals
of many use. As there is no range land in our country,
these animals graze in the forest and there is no way
to stop it. During grazing, browsing and trampling
they eat and destroy the young seedlings and thus
cause imbalance in the natural ecosystem. Failure of
plantation and coppice area occured many years in the
past due to this uncontrolled grazing. Such situation
arises when large areas adjacent to the villages are
taken up for plantation in the same year. The villa
gers suffers badly from the want of grazing land and
make non-cooperation in raising new plantation. Some
times they damage it by cutting and pulling the seed
lings and make the plantation a failure. Finally the
villagers use it as a grazing field.
5 FIRE HAZARD
Every year the ground fire over run the whole forest
during the summer. It has been mentioned that the sal
forest is a deciduous forest and the dry leaves accu
mulate on the forest floor during the month of Febru
ary and March and make a thick carpet of leaves under
the trees. This time the grasses also dry up. It has
been found that the fire is mostly intentionally
started in the forest by the owner of the agricul
tural land or by their shepherds with a view to burn
the leaves and grasses. The ashes thus produce is
washed down by subsequent rain to the baidland and
increases the fertility. Some times the fire also
start from the burning end of cigarettes thrown by
the workers.
The top soil on the forest floor losses all humess
and the existing regeneration die back. Sal seeds
which fall during the month of May germinate profusely
on the bare ground and die back Sal seedlings give
rise to vigorous coppice shoots. But the young coppice
losses the early growth. New and young plantation
beceunes a failure due to death of seedlings by such
ground fire. No crown fire have ever been seen in
this forest area.
6 LAND FOR PUBLIC INTEREST
For the sake of public interest some establishments
have been built up in the forest area. Bangladesh
Defence Department, Bangladesh Air Force, Bangladesh
Railway, Machine tools factory, Roads and High Ways
and Radio Bangladesh have acquired a vast area of
land. Many market places have also been developed in
and near the forest area. The forest undoubtedly
suffers from their indirect long and short term
pressure continuously.
7 RECREATIONAL FACILITY IN THE FOREST
About sixteen thousand acres of forest land has been
declared as Bhawal National Park to provide recrea
tional facility to the people of the Dhaka Metropo
litan city and the people living around area. The main
centre of the park is situated on the Dhaka - Mymen-
singh High Way which is about 26 miles away from the
Dhaka city. The forest was subject to serious biotic
interference for the last two decades and crop condi
tion was deteriorated and threatened the very exis
tence of the forest in the region. There is a steady
rise in the number of local visitors since the inau
guration of the Park in 1974. For the present more
than thirty thousand picnickers enter into the Park
area by week end during winter. The visit of the
foreign national are also increasing. This recrea
tional facility in the forest indirectly assists in
preserving the flora and fauna and prevents the people
from doing damage to the forest resources. More over
the development of tourism will create opportunities
for employment as guide, assistants and in various
ancillary services for lot of local people who might
otherwise engage in illegal shooting, timber cutting,
cultivation and other desruptive uses of forest eco
system.
8 ARTIFICIAL PLANTATION
Due to political disturbance in the country during
1969-70 and 1973-74 the forest suffered very badly.
The uncontrolled felling and encroachment turned the
major area of the forest clear and the valuable old
plantation were damaged by miscreants. A B a result
whole of the Dhaka forest became abnormal and con
verted to a coppice forest of one to fifteen years
old. To stop further deterioration of the forest the
extraction were completly stopped and the encroached
area were planed to recover by reforestation. Since
1970 some of the recovered blank areas have been
planted up with first growing valuable species like
Minjri (Cassia sia mea), Mahogony (Swietenia macro-
phylla), Neem (Melia spp.), Gamar (Gmelina arborea),
Teak (Tectona grandis), Jam (Eugenia jambolana),
Jarul (Lagerstroemia flosreginas), Koroi (Albizia
procera), Kadom (Anthocephalus cadamba), Gazari
(Shorea robusta), Babul (Acacia arabica) etc. Exotic
trials with Eucalyptus and other species have also
been given in the area and the result is very good.
Nearly four thousand acres of land have been reforested
by now to increase the forest cover.
9 WILD LIFE
Once the forest was full of with various wild animals
and birds. Among these leopard, wild boar, barking
deer, monkey,, jackle, fox etc. were very common
animals. Different kind of beautiful birds and birds
of prey also lived there. Now a days they Eire not seen
at all in the forest area without some minor species.
They have been eradicated due to illicit hunting and
change of environment. As a result the ecosystem of
the forest has totally been lost which has severe
impact on natural growth and vigour of the forest.
10 PHOTOINTERPRETATION RESULT
The aerial photographs of the study area flown in
1952, 1975 and 1983 were studied under mirror stereos
cope. Landsat imagery of different year have also been
studied. The forest cover, new plantation, villages,
market places, scattered huts etc. have been identi
fied. The height classes in some places have been
improved. Some forest have been converted into scrub
forest. Settlements and habitation have been increased.
The area of scrub forest has also been increased. More
areas have gone under arable land and fruit orchard.
The forest cover of the above period have been measured
independently. In 1952 the forest area covered appro
ximately 230.0 sq km. In 1975» it did not change
