Sissoo (Dalbergia sissoo), koroi (Albizia procera), akashmoni (Acacia auriculiformis),
babla (A. nilotica), mahogany (Swietenia macrophylla) and raintree (Samanea samari) are the six
major species planted on the embankments and roadsides in the coastal areas of Bangladesh.
Growth data of these species were collected from the area, and growth models were selected by
regression techniques. The selected models may be satisfactorily used for the species in the area.
This paper attempts to explore the impacts of villagers living in the vicinity of the forest
area on forests and forest resources. For this, a survey was conducted on 171 households of eight
locations. The households were grouped into three farm categories upper, middle and lower.
From PRA exercise it was found that there was an overall shortage of fuel wood and other low
cost house-building materials. The villagers were partially dependent on the forest resources. The
lower farm category had the lowest number of bamboo than those of the upper and middle farm
categories. In upper, middle and lower farm categories, the forest and non-forest tree ratios were
found to be 67:33, 41:59 and 72:28 respectively and for all it was 60:40. The average tree income
ratios of homestead and forest were 57:43, 38:62 and 29:71 for the upper, middle and lower farm
categories respectively and for all it was 41:59. The average incomes from the business were 63%
for upper and 73% for middle and lower farm categories. The major shares of income (70%) came
from the business. Highest (25%) depletion of forest resources were in Bagerhat and the lowest
(4%) in Noagaon. It was elicited that the forest was depleted by about 12.5% annually.
Survival percentage and height growth of four types of planting propagules (stumps, poly
bag seedling, stumps in poly bag and direct seed sowing) of Gmelina arborea were studied at
Charaljani. Charkai, Keochia and Lawachara Silvicultural Research Stations located al different
regions of Bangladesh. There was no significant differences in the average survival percentage
among the polybag raised seedlings, stump planting, stumps in polybag and seeds directly sown in
the fields. The average survival percentage was 45% to 91% at four sites at the age of 2 years 4
months at Charaljani, Keochia, Lawachara and 1 year at Charkai Silviculture Research Station.
The difference in total height growth of four types of planting propagules was found statistically
significant. The highest height growth (263cm) was obtained in polybag raised seedling at
Charaljani followed by 105 cm at Keochia, 88 cm at Lawachara at the age of 2 years 4 months and
139 cm at Charkai at the age of 1 year after out planting. However, there was no differences in
height growth between the polybag seedlings and stumps in polybag at Lawachara Silviculture
Research Station.
Welcome to the Bangladesh Journal of Forest Science (BJFS) – a leading platform for advancing the knowledge and understanding of forest science in Bangladesh and beyond. Established with a commitment to excellence, BJFS serves as a cornerstone for researchers, practitioners, and enthusiasts dedicated to the sustainable management and conservation of forest ecosystems.
