Abstract:

Oil palm (Elaeis guineeiisis Jacq.) is
indigenous to West Africa (Zeven 1965,
Hartley 1967) where it grows wild in a
320-480 km coastal belt from Gambia to
Angola (Moe and Mohtadi 1971) E. guineensis
var. tennera, with thinner shelled fruits,
is a hybrid of ‘dura’- a wild variety with
thicker shell and ‘piscifera’ with no shell
(Rahman et al 1979). It is an exotic high
oil yielding fruit crop from Malaysia and
introduced in Bangladesh in 1978-79 with
a view to developing the domestic nonconventional
source of vegetable oil to
meet the demand of both edible and industrial
oils of the country. As such, Bangladesh
Forest Department initiated raising 4047
ha of oil palm plantation in the high
rainfall regions like Chittagong, Chittagong
Hill Tracts, Cox’s Bazar and Sylhct Forest

Abstract:

Mangium (Acacia mangium willd) is a
promising fast-growing multipurpose species
of the family Leguminosae and subfamily
Mimosoidcac. It is indigenous to
northern Australia, Papua New Guinea
and eastern Indonesia. The best known
stands are found in Queensland, Australia,
where the temperature ranges from 12°c
to 34°C and about 4,400 mm and 700 mm
rainfall are received annually during the
rainy and dry seasons respectively.

Abstract:

Rakta Kambal (Adenanthera pavonia
Linn. ; Family : Leguminosae, Sub-Family ;
Mimosoideae) is a moderate sized deciduous
tree of the eastern Sub-Himalayan tract,
Burma, the Andamans and the Western
Ghat (Troup 1921, Anon. 1948). The
red wood of Rakta, Kambal is reported to
be used as a substitute for true sandal
wood (Anon. 1948). This tree grows well
in moist areas and is propagated by
cuttings (Troup 1921, Anon. 1948). It is
often planted in road side plantations
especially in southern India. Troup (1921)
reported that the seed of Rakta Kambal
is difficult to germinate.

Abstract:

Behaviour of different birds and its
effects on agricultural crops were studied
in charland of the Padma belt under
Rajshahi district. A list of different migratory
and resident birds were prepared and
effects of those birds on agricultural crops,
mainly rice, were observed. The study
revealed that most of the birds are useful for
agricultural crops as they live on injurious
insects and thus save the crops from
destruction.

Abstract:

Sporadic mortality of Sundri (Heritiera
fames Roxb.) due to unknown causes
was mentioned in the working plan of
Sunderbans in 1931 by S. I. Curtis. But the
mortality was not pronounced due to
removal of Sundri along with firewood
by permit holders. After 1971 working was
closed for a few years and as such accumulation
of dying Sundri in large number
attracted the attention of the foresters
(Sattar 1977). The total timber loss due to
mortality of Sundri was found to be 1.44
million cubic metres and the total financial
loss on the basis of valuation of 1976 was
Tk. 2000 million (Shafi 1982).

Abstract:

During data collection for preparation of volume functions for
high forest species at Cox’s Bazar Forest Division, some photographs
of wood stacks were taken in order to find a relationship of stacked
volume versus solid wood volume. The stacks were composed of
round woods of varying sizes. The photographs in black and white
were taken from three places of Cox’s Bazar Forest Division.

Abstract:

Traditional wood having high natural
durability and other desirable properties
are becoming scarce and as such the
use of alternative non-traditional woods
has become very common. Bandarhola
(Duabanga sonneratioides) is one such nontraditional
timber species which is available
in large quantity and is being used in an
increasing rate in various types of light
constructions. However, like most wood
species of Bangladesh, it is not naturally

Abstract:

Bamboo blight causes mortality of
emerging, partly grown or fully elongated
culms. Symptoms and causal pathogens have
been described by Rahman (1978) and Rahman and Khisha (1983). Boa (1983)
has reported the distribution of the blight
and relative susceptibility of various bamboos
in Bangladesh. Bambusa balcooa Roxb,

Abstract:

Bent solid wood is advantageously
employed in fabricating a variety of products.
Bending is an economical technique
in the manufacture of sports goods, walking
and umbrella sticks, chair parts, barrel
staves, wood rings and covers. Some work
has been done to evaluate the bending
characteristics of woods in many countries.
The level of moisture content of wood
and the period of steaming in the process
of bending are considered important criteria
for bending wood (Anon. 1948, Anon.
1959, Anon. 1967, Martin and Wangaard
1950, Rehman et all 1956). However, no
detailed study has been made on Teak
wood in this regard. It is, therefore

Abstract:

Teak (Tectona grandis L.) is the premier
species both in terms of properties, and
appearance and is the top demanded
species in Bangladesh. In recent years, heavy
demand of timbers in the industries has
led the Forest Department to choose fast
growing species on short rotations. Still
the demand of Teak for constructional and
cabinet manufacturing purposes and also
for export is very high. It is, therefore,
being planted only under the long rotation
cycle.
Stump planting is the usual practice
for raising Teak plantations. Seedlings are
raised in the nursery, one year ahead, for
stump-planting during May-June in the
