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

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,

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.

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.

Introduction
Eucalyptus is a large genus of family wyrtaceae which
comprises over 500 species, varieties and hybrids. Most of the
species are indigenous to Australia, Tasmania, New Guinea and the
neighboring islands, where they constitute a large portion of
forest vegetation. This being one of the large genera, a great
number of classification schemes have been proposed since its discovery but the system now in use and universally accepted is based
on shape of the anthers.
Eucalyptus are among the world’s important hard woods
and the principal source of timber in Australia. Besides, Eucalyptus oil has got also much importance in commerce. Cultivation of
Eucalyptus got momentum due to its commercial importance throughout the world. Further, rapid growth, ease in cultivation and adoptability have also helped much in wide spread introduction into
many countries specially those poorly endowed with forest resources.
This plant has become such an important factor in the economy of
some countries that millions of trees are now being planted each
year throughout the world.

During the months of June and July, 1970, severe defoliations of
young teak plantations were observed in several localities of Chittagong,
Chittagong Hill Tracts North and Cox’s Bazar Divisions ( see Table I ) •
Especially leaves in the upper part of the crowns were eaten causing the
teak look rather naked as during winter time. The leaves were eaten up
except the major veins, as showns in Figure 1 •

Like the starving man of legend many developing countries are
sleeping, unaware, on a heap of gold.Most of the largest and richest
tropical rain forests are located in the “Third World”, but for the
mosy part they are unexploted, ignored, unattended or poorly managed.
And it is in these regions that hunger and poverty are most acute.
There would seem little- if any- connction between developing
forest land and solving the hunger problem. But it has become increasingly clear to economic planners and developing experts that the two
are so closely linked that in the years ahead forestry would be a key
factor in the fight against hunger.
