| dc.description.abstract | Sal (Shorea robusta) is an important timber species which is found in the natural Sal
forest of Bangladesh. The tropical moist deciduous Sal forest ecosystem of Dinajpur is
currently in a critical situation. Destructive anthropogenic and natural impacts coupled
with overexploitation of forest resources have caused severe damage to the forest
ecosystem. In recent years the problem has assumed serious magnitudes. To protect Sal
forest, cane plantation was done in 20 ha. area during 2013-2014 session in Nawabganj
Sal forest and also done in some areas of the Singra Sal forest under the management of
forest department. Though the program seemed to be successful, but it was not suitable
for natural regeneration of Sal tree due to the bushy nature of cane plantation. The
present study was an attempt to identify the current status of cane plantation in the Sal
forest of Dinajpur and to explore the impact of cane plantation on the regeneration of Sal
forest. The study was conducted in the Sal forest of Dinajpur district at two different
locations namely Birganj and Nawabganj upazila during September 2018 to November
2019. Ten quadrates were selected randomly inside each Sal forest for this study. Five
quadrates were Sal with cane species and five quadrates were only Sal species without
cane species. Altogether twenty quadrates were selected in two Sal forest. The size of
each quadrate was 20m×20m. Number of big Sal trees greater than 3 feet height, number
of Sal seedlings below 3 feet height, number of Sal coppice seedlings below 3 feet
height, number of Cane bush, number of germinated seedlings of Sal, number of Sal
seeds per sq. m, height of Sal trees, diameter at breast height (DBH) of Sal trees, weight
of leaf litter per sq. m etc. were measured from the sample plots (20m×20m). The overall
results of the study revealed that all the parameters decreased due to cane plantation in
the natural Sal forest which was responsible for poor regeneration of Sal seeds for the
bushy structure of cane. Such as the average number of Sal trees (2022 and 1240) and
average volume of Sal trees (40882 cft and 36351 cft) found per ha in only Sal and Sal
with cane plantation in Dinajpur Sal forest. For better management of Sal forest cane
plantation at the floor of forest should be restricted immediately. | en_US |
