“…Several researchers [1,5,7,8,[17][18][19][20] have studied anthropogenic disturbance and its consequences on plant species diversity in Bangladesh's moist deciduous forest and other forest ecosystems in world perspective. Previous studies have elucidated how human disruptions affect species composition, structure, and regeneration.…”

Industrial activities have various effects on biodiversity, posing significant threats to forest ecosystems. The current study describes the species composition, taxonomic diversity, and stand structure at Bhawal Sal forest, Gazipur, Bangladesh, as they are affected by industrialization. To achieve the goal, 30 different categorized industries within the forest were considered sampling points and three distance gradient sites viz. Site-1 = Adjacent to industries (0 m), Site-2 = 160 m distance and Site-3 = 320 m distance from industries were designated as treatments. A total of 90 quadrate plots (10 m × 10 m) were taken randomly, of which 30 plots were from each site. Through forest inventory, 46 species (24 trees, 8 shrubs, 5 climbers, and 9 saplings) were recorded from three sites. The study revealed that the stand density and basal area of mature trees (257 stems ha−1 and 8.06 ± 0.60 m2·ha−1) at Site-1 were significantly lower due to diverse industrial operations than other sites. Statistically, all the biodiversity indices of mature trees; Shannon–Wiener’s index (1.72), Simpsons index (0.82), Margalef’s index (1.38), Pielou’s evenness Index (0.39) was found to be lower at proximity to industries. The lowest species richness (12) of all plants was recorded from Site-1. However, the diameter and height distributions of Site-1 comprised young (10–20 cm·dbh) to medium-sized (20.1–30 cm·dbh) trees, while the medium to large sized (>30 cm·dbh) trees was contained at Site-3 in this study. The population structure of tree species at Site-1 also showed a fluctuating curve. Overall, this study highlights that plant ecosystems and tree population structure have declined tremendously due to industrialization. Hence, the current research could be significant for developing the management framework for the disturbed deciduous forest.

“…The Sal forest (Shorea robusta) is considered one of the richest ecosystems regarding forest diversity in Bangladesh and a very large portion of such forest ecosystem lies in the districts of Mymensingh and Tangail known as Madhupur Sal Forest (MSF). Geographically, this forest is located from 23°50′ to 24°50′ north latitude and 89°54′ to90°50′ east longitudes at a distance of about 96km north from capital Dhaka (Hasan et al 2020). The total area of the MSF under the Tangail district is about 46,000 acres (186km 2 ) and this forest is a highly diverse and productive ecosystem having some 271 species of which 41 are tree species (Ahmed 2009).…”

The litters in the forest floor are the principal contributor for regulating the cycling of necessary elements, primary productivity and maintain soil fertility within the forest ecosystems. Therefore, this study was conducted in a deciduous forest of Bangladesh to ascertain the leaf-litter production and decomposition along with elemental dynamics (K, Ca, Mn, Fe, Co and Zn). Leaf-litter samples from five deciduous plant species and soil samples were collected from the Madhupur Sal Forest for about six months (July-December) in 2018. Production of leaf-litter during the dry season (December) was found in an order of Shorea robusta>Dipterocarpus indicus>Terminalia bellirica>Tectona grandis>Grewia microcos. The decomposition rates were higher for the long sampling period (90 days) followed by the intermediate (60 days)> short(30 days) sampling period. The nutrient release pattern from the leaf-litter was similar (Ca>K>Mn>Fe>Zn>Co) for all plant species except for Terminalia bellirica and Tectona grandis. The Pearson correlation coefficients showed a significant relationship between K and Fe (r=0.54; p<0.05), Ca and Co (r=0.59; p<0.01), Fe and Co (r=0.97; p<0.05) in leaf-litters. Analysis of variance (ANOVA) revealed significant variation in the litter production, decomposition and nutrient content (except Zn; p>0.05) among the different plant species (p<0.05). There revealed a significant dynamic of necessary elements from soil to trees and vice-versa.
