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.

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).

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.

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

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,

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

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

Bangladesh is deficient in vegetable
oils. Indigenous sources of vegetable oils
are the agricultural oil crops. Soyabean, coconut,
sunflower and other vegetable oils are
imported to supplement the quantity
produced in the country. Because of acute
shortage of agricultural land, the possibility of increasing oil production by bringing
more agricultural land under cultivation
of oil crops is remote

Sundri (Her Hi er a fames Buch.-Ham.)
is one of the important tree species of the
tidal forests of Sunderbans having wide
range of uses from fire-wood to cabinet
making. Now a days it is the chief raw
material for making hardboard. Other
important uses are as props and transmission
poles. Ecologically, it is considered as the
climax species of this region (Champion
et al 1965) and has been growing well
in those regions of Sunderbans where salinity
is relatively low.

The forests of Bangladesh consist of
three major vegetation types occurring on
three distinctly different geomorphological
units : (i) the Tidal Swamps, consisting of mangrove forests (ii) the High Terraces,
consisting of deciduous forests and (iii)
the Tertiary Hills, consisting of mixed
evergreen forests. Soils of Bangladesh
