Introduction :
■ Watershed management is concerned with the hydrologic
effects of land use and vegetative management. Water is considered
a product of the land which, within limits set by nature, can be
managed just as other renewable natural resources. In watershed
management the emphasis is not on harnessing water in streams but
on managing on the land itself, before it enters the streams or
.ground water basins. Watershed management may be called as handmaid of Engineering Water Development. This is most evident where
engineering structures erected for better water supply and regulations of stream discharge are threatened by erosion and premature
sedimentation, where the remedy lies in the introductionof conservative land use practices and suitable vegetation patterns combatable with the water producing function of

with a little dispassionate thinking one is
likely to conclude that possibly no other natural resource
of the world has been so shabbily treated by the human beings
as the forests had been from the pre-historic days till
to-day, both collectively and individually. The original
inhabitants of the earth lived mostly as denizens of the
forests depended on forests and forest products for their
food and shelter. But they gradually cleared the forests
to their advantage to live a better life away from the
forests. New society has grown, new civilization built up,
new kingdom established, new economy flourished at the cost
of and on destruction of forests. But hardly people have
realised its importance or care to look back with any sense
of gratitude to this important natural resource of the world,
is so vital even in the modern civilized society. Forest and
forest products have been playing important role to the
nations in support of agriculture , in the growth of industry, giving protection in natural clamities and making provision for its growing population in earning livelihood and
thereby helping economic development of nations in earning
or saving foreign exchange. Forest products are again in
the service of any individual from T cradle to coffin1 but
very often an individual offers his gratitude by using his
injudicious brutal axe in cutting a mighty tree, which might
have grown for over hundred years serving his fellow men for
generations, and even without caring to replace this gift of
nature by planting atleast a similar one is a suitable pice.

Pakistan consists of two regions, viz., East and West
Pakistan, separated by nearly 1,000 miles of Indian territory,
climatic conditions, the soil and forest types of these two regions
are varied. On the national basis, less than ten per cent of the
total land area is classified as forest and range land. In-East
Pakistan, however, 17.3 per cent of the land area is forest land of
which approximately ten per cent is under scientific management and
the remaining 7.3 per cent is in the category of unclassed state
forests where shifting cultivation by the tribal people is practised.
Less than one third 01″ the forest area in West Pakistan is regarded
as productive forest hind and the balance is range land,

One of the chief disadvantages of wood in use
is its inability to retain its shape with the change in
the moisture content. It shrinks and swells as water is
desorbed or adsorbed in the cell wall of the wood fibre
which is composed primarily of cellulose ‘mnicrofibrils.

Introduction :
This paper describes the paper making properties of
various types of paper prepared from the mixture of 8(eight) minor
hardwood species, viz, Itchri (Anogeissus acuminata), Amra
(Spondias pinnata) , Barta (Artocarpus lakoocha), Champhata
(Sapium baccatum) , Gutgutia (Walsura robusta), Chakua koroi
(Albizzia chinensis) , Kuramara (Pithecolobium angulatum) r -Jagga
dumur (Ficus glomerata). These minor hardwoods are scattered all
over Chittagong and Chittagong Hill Tract areas. In an earlier
work conducted in this Institute (1) chemical and semichemical
pulping studies of these mixed species were performed and the
effects of various pulping variables on the resultant pulps were
determined.

The part of Bengal bounded by the river system
Brahmaputra-Jamuna-Ganges to its North is generally known as
, North Bengal. The portion of North Bengal which came to Pakistan
and ’’Khiar”. ’Poli’
after independence of the country inherited small’areas of
natural forests. The scope of this papfer is limited to the
Pakistan portion of the North Bengal. Of the five Civil
Districts of North-Bengal namely, Rajshahi, Rangpur, Dinaj pur,
Pabna and Bogra, there is no forest at all in Pabna and Bogra.
About 85.5%: of the forest areas are situated at Dinajpur
district, 11,6 at Rangpur District. but* contiguous to the
, r ’ ‘• ■ ■ Dina.jpur forests and 2.5% at Rajshahi. The.forests of the
present Rajshahi district were also the part of undivided
Dinajpur district but became intercepted due to partition of
Dinajpur district-at the time of Independence.

Introduction :
leL.O./F.A.O. Course on forest working techniques and
training of forest works for countries in Asia and the Far East
was spread over four weeks. The first week was devoted only.jln
lectures, the next two weeks to field demonstrations of the operations already covered in class room lectures and the last week to
final reviewing of the previous lectures and the field demonstrations. The course covered the following subjects :
Timber cruising and marking,
Road planning and building,
Timber felling techniques with hand tools and with power saws,
Timber skidding, yarding and swinging,
Timber transportation by trucks,
Use & maintenance of hand tools, power saws & heavy equipments,
Timber grading and scaling,
Medical problems of iorest workers,
Need for vocational training of forest workers,
Work studies in forest operations.
