“…Moreover, present study exceeds the findings of Nur et al (2016) where, they found 36% of the tree species (17 out of 47) are regenerating in the study area, while majority of the tree species (64%) are not getting favorable conditions to regenerate. However, the conservation status of regenerated seedlings of current study is an agreement with the findings of Chowdhury, Hossain et al (2018) where they found most of the plants were belonged to the Least Concerned (LC) category in Rangamati.…”

“…Present study showed G. nervosa had the maximum IVI (23.97) value followed by S. robusta (21.02). However, Chowdhury, Hossain, Hossain, and Khan (2018) studied regeneration diversity of Rampahar Natural Forest Reserve in Rangamati South Forest Division, where they recorded the IVI values of regenerating tree species was highest in P. serratum (50.09) followed by B. ceiba (39.37).…”

Enumeration of regeneration status is an authentic tool to know the actual condition of forest ecosystem. The study was conducted to assess the regeneration status of Durgapur hill forest following stratified random sampling method (2 m × 2 m quadrate) from October 2017 to May 2018. A total of 27 species under 18 families were recorded from the study area. The study revealed maximum (37.78) family importance value (FIV) index was recorded for Euphorbiaceae followed by Moraceae (16.09). Importance value index (IVI) of Grewia nervosa was maximum (23.97 out of 300) followed by Shorea robusta (21.02), and Aporosa wallichii (20.19). Conservation status showed highest (77.78%) plant species were in least concerned (LC) where only one species (Dillenia pentagyna) was found as data deficient (DD) category. Seedlings of different height classes showed maximum (33.2%) seedling were within the height range of 50-<100 cm. However, different biological diversity indices, i.e., Shannon-Winner index (H) (4.27), species evenness index (E) (1.30), Simpson index (D) (0.15), and Margalef's species richness index (4.24) were enumerated to know the complete diversity condition of the forest area. Hierarchical cluster of the recorded species also showed that Grewia nervosa is the most dominant species in that area. ARTICLE HISTORY

“…According to [34], the regeneration status of a forest is poor if number of seedlings and saplings are much less than mature individuals. The regeneration status of current study is an agreement with the findings of [35] where they found most of the plants were belonged to the Least Concerned category in Rangamati.…”

The dry land forest of Ethiopia possesses diverse tree species that are known for their ecological and economic values. Despite growing recognition of environmental and economic benefits of these species, the woodland harbouring these species is degrading. Adequate knowledge on the resource base including the current status of its population is crucial for sustainable management of the forest resource. Therefore, this study was carried out to investigate the diversity and composition of woody species in Kara dry lands forest. A total of 90 quadrants were established along transect lines. A 400 m 2 quadrants was used, distance between quadrants and transecting lines were 200 m and 500 m respectively. Species diversity and evenness, density, frequency, important value and regeneration status were assessed. This study reveals total of 48 woody species representing 23 families and 31 genera's were found. Out of that, 13 woody species were identified as gum and resin bearing species. The genus of Commiphora and Acacia species were found to be the dominant gum and resin bearing species at the study area. Diversity of the entire woody species assemblage and of the gum-and resin-bearing species was H= 3.47 and H= 2.3 respectively. The evenness values of entire and gum and resin producing woody species were 0.67 and 0.77 respectively. The gum and resin producing woody species accounted for 44.56% of the density, 49.87% of the basal area and 45.49% of the Importance Value Index. However, we recorded the declining natural regeneration of most gum-and resinbearing woody species except for a small number of species, which exhibited signs of healthy populations. Generally, the results of the present study highlighted the absence of conservation actions that will probably be subject to a progressive decline of gum and resin bearing species because of uncontrolled grazing, charcoal production and shifting cultivation. Therefore, proper management plan and domestication of the species through artificial regeneration and area closure are urgently needed.

“…The tree species composition of DHF (56 tree species, 50 genera, 29 families) is closer in relation to tropical forest, i.e. 50 tree species in Rampahar Natural Forest Reserve (Chowdhury et al 2018a), 52 tree species in Kaptai National Park (Rahman et al 2016), 62 tree species in Tankawati natural forest (Motaleb and Hossain 2011). However, DHF also possesses lower tree species in comparison to 107 tree species in Kamalachari natural forest, Rangamati and Bandarban borderline (Hossain et al 2015), 153 tree species in Tropical Forest of Eastern Ghats, India (Reddy et al 2011) and 93 tree species in Chunati Wildlife Sanctuary (Nath et al 2016).…”

“…In government managed forests of other parts of Bangladesh, many researcher investigated plant species diversity and forest stand structure (Nath et al 1998;Nath et al 2000; Motaleb and Hossain 2011; Hossain et al 2013; Feeroz and Uddin 2015;Hossain et al 2015;Chowdhury et al 2018a, b;Das et al 2018). But, Durgapur Hill Forest (DHF) lacks information regarding structural composition, stocking and conservation issues.…”

Abstract. Rahman MdR, Rahman MdM, Chowdhury MdA, Akhter J. 2019. Tree species diversity and structural composition: The case of Durgapur Hill Forest, Netrokona, Bangladesh. Asian J For 3: 10-19. Tree species diversity and stand structure of Durgapur hill forest were assessed through stratified random sampling method using sample plots of 20 m x 20 m in size during the period of October 2017 to May 2018. A total of 1436 stems of ≥5 cm DBH of 56 tree species belonging to 50 genera and 29 families were enumerated from sample area. Density (855 stem ha-1) and Basal area (29.27 m2 ha-1) of tree species were enumerated. Besides, Shannon-Wiener’s, Margalef’s, Simpson’s and Pielou’s diversity index were recorded for all the tree species. The study showed that the most dominant 10 species have 58% of the total IVI (174.29 out of 300). Where, Acacia auriculiformis showed the maximum Importance Value Index (51.02) followed by Shorea robusta (24.23). Number of individual tree species were highest (49) in the height range of 7- <12 m whereas maximum (52) species were recorded in the DBH (cm) range of 5- <10 cm. However, Acacia auriculiformis, Shorea robusta, and Tectona grandis were found as the most dominant species based on hierarchical cluster analysis. Therefore, current study will be helpful to the future policymakers in formulating forest resource management plan of Durgapur hill forest.
