A Half-yearly Peer Reviewed Journal of Bangladesh Forest Research Institute
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.
What is Paper?
Paper is a common and familiar material used in our day
to day work. The precariat production and consumption of paper
in a country reflect the extent of development of tha.t country.
• 1 f •
Paper is so much co-related to us that we cannot dream of happy
and worthy life without it. Our knowledge remains self-centered
if we fail to have some idea about this important pillar of
civilization.
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.
Introduction
In East Pakistan due to various pressure on the sal
forests, the original crop lias deteriorated further in its
genetic composition, bo vigorous attempts have to be made to
Shorea robusta’, a member of the genus Shorea, belongs
to the family Dipte.rocarpaceae0 Sal (local name) occupies
two main regions of the subcontinent (separated by gangetAc
plain) the Northern and the Central region of Indo-Pakistan,
In East Pakistan it occurs in three areas Dacca, Mymensingh
and Dinajpur-Kangpure Dacca-Mymensingh sal is the tail end
of the Eastern range following Garo Hills of Assam (India)
where_as the Dinajpur-Kangpur sal is the continum of Bengal
Duars.
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 •
Gamari or Gamar is a well known furniture wood in
East Pakistan, particularly in Chittagong. The botanical
name for Gamar is Gmelina arborea, Roxb. , and it belongs to
the family Verbenacr.c to which teak belongs. The generic
; Melina) is named after S.Gottlieb
The la’<in rceanirg of ’’arborea” is
Local names : Gamari; Gamar (Chittagong, Chittagong
Hill Tracts, bylhet), Joginichakra (Mymensingh), Ramani (I'lagh)
Gambar, Bol-gippok (Garo), Kumhar, Gumhar, Gumliar (W.Pak.)
In Burma} the plant is known as Yemani, Name used in the exotic plantations, e.g, Nigeria, is Gmelina or Yemani. In English it is known as Kashmir tree or white teak.
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.
