Abstract:

The Sundarbans mangrove forest is well
known for its rich biodiversity and probably has
the maximum flora and fauna as compared to
other mangrove forests of the world. Prain (1903)
reported 334 plant species in the Sundarbans and
surrounding areas. It is a matter of concern that
there is a loss of biodiversity in the Sundarbans
mangrove forest. Sattar and Faizuddin (1998)
reported that one species of Briiguiera, that is
B. parviflora, has become extinct, and many other
plant species such as Luninitzera racemose,
Xylocarpus granatum, Aviceunia marina, Rhizophore
mucronate, R. apiculata, Kandelia candel, Excoecerie
indice, Cynometra remiflore and Amoora cuculate are
already threatened. Chaudhuri andNjiithani(1985)
did not mention the presence of B. parviflora in the
Indian part of Sundarbans but noted its presence
in the Andamans mangrove forests. It used to be
found associated with other mangrove species in
the Sundarbans on the bank of rivers and creeks
(Naskar and Guha Bakshi 1987). The timber of B.
parviflora is used as fishing pole and firewood. It is
also a fodder plantfor deer and other herbivorous
animals

Abstract:

This paper gives an overview on the initial growth performance ofmahogany
(Swietenia macrophylla King) planted in Chittagong city areas of Bangladesh. A guide
equationwas derived with logarithm to the base e of dominant height as a dependent
variable and reciprocal power of age as an independent variable. The growth
characteristics were estimated by regression techniques based on statistical and
biological criteria. The paper presents the growth statistics ofstand diameter atbreast
height, stand mean height, stand dominant height and basal area per hectare. The
selected models could be used to estimate the growth parameters in the plantations
with 9.0 m to 21.0 m dominant height at the age of 12 years.
