“…Overall, the two AAC presents a diversified and equitable specific richness. Our results converge with the works of [64] which stipulate that when the equitability is high, the dispersion of the elements of biodiversity would be equitable. Finally, the correlation between the age of the road and the indices of diversity showed that there is no link between the ages of secondary roads post-logging and the indices of diversity (p-value > 0.005).…”

Natural regeneration is the basis of a dynamic and demographic balance of plant populations. The objective of this study was to assess the natural regeneration potential of woody species along secondary roads post-logging abandoned since 2008 and 2018. In the two Annual Allowable Cuts (AAC 2008 and AAC 2018), 24 regenerating sub-plots (i.e. 12 sub-plots for AAC 2008 and 12 sub-plots for AAC 2018) with a unit area of 5 m × 5 m were delimited with a total area of 0.06 ha (i.e. 0.03 ha for each AAC). The abundance and diversity of woody species were respectively inventoried and estimated. Two estimators of the specific richness were used to estimate the floristic diversity of each Annual Allowable Cuts (AAC). The results reveal globally 88 woody species in the AAC 2008 and 241 woody species in the AAC 2018, with respective average densities of 2933 stem/ha and 8033 stem/ha. There was a very highly significant difference between the mean densities of the two AAC (Kruskal-Wallis test; H = 2.36, p-value < 0.000). The results also highlight a great diversity and a relatively high abundance of woody species in the 2018 AAC compared to the 2008 AAC. Also, the spatial structuring of the sub-plots on the basis of Principal Component Analysis (PCA) demonstrates that the floristic composition of the two AAC is globally different. The study suggests silvicultural interventions and the long-term assessment of regenerating woody species along abandoned secondary roads in order to guarantee the sustainable management of their population.

“…In CWS, the number of naturally regenerating species (105) and family (35) was higher than that of similar natural forests of Bangladesh. Rahman et al (2019) enumerated 56 naturally regenerating species from Durgapur hill forest. Hossain et al (2004) reported 64 naturally regenerating tree species from natural forests of Chittagong (South) Forest Division.…”

PurposeIn this paper, the authors show that ecological restoration potential through natural regeneration of degraded tropical rainforest is possible. This is significant because at present most of the tropical forest of the world, including of Bangladesh, are degraded.Design/methodology/approachRegeneration status of Chunati Wildlife Sanctuary (CWS) was assessed through stratified random sampling method using sample plots of 5 × 5 m in size covering 269 sample plots.FindingsA total of 3,256 regenerating seedlings/saplings of 105 species belonging to 35 families were recorded from CWS. From regenerating tree species, maximum (37.83) family importance value (FIV) index was found for Euphorbiaceae followed by Myrtaceae (18.03). Maximum importance value index (IVI) was found for Aporosa wallichii (21.62) followed by Grewia nervosa (16.41). Distribution of seedlings into different height classes of regenerating tree species was also calculated.Practical implicationsForest scientists are working to find out the best nature-based solution for ecological restoration of tropical rainforests to attain climate resilient ecosystem in a sustainable way. Tropical rain forest has huge plant diversity, and we find that ecological restoration is possible through natural regeneration from its rich soil seed bank. Natural regeneration is the best nature-based solution for sustainable management of the forest.Social implicationsThe authors believe that the findings presented in our paper will appeal to the forest and environmental scientists. The findings will allow readers to understand degraded tropical hill forest ecosystem and its management strategy.Originality/value The authors believe that this manuscript will give a clear picture about degraded tropical hill forest ecosystem and its genetic composition, diversity and soil seed bank status to apply appropriate management strategy.

“…Durgapur hill forest is one of the remnant places of Sal forest patches in Bangladesh where economically and ecologically valuable tree species are needs to be prioritized for conservation and scientific management (Rahman, Rahman, Chowdhury, & Akhter, 2019). The forest has been cleared brutally within the last 30 to 50 years as the demand for energy, construction, wood, food, fodder has increased as a result of the increase in both human and livestock.…”

“…The main causes of deforestation and forest degradation in this area were tree cutting for fuelwood, and construction materials production for sale especially. A number of studies are available focused on natural regeneration status in different natural forests of Bangladesh provide potential information for many native tree species (Haider et al, 2017;Hossain, Hossain, Salam, & Rahman, 2013;Hossain, Azad, & Alam, 1999;Hossain & Hossain, 2014;Motaleb & Hossain, 2007;Miah, Udin, & Bhuiyan, 1999;Nur, Nandi, Jashimuddin, & Hossain, 2016;Rahman, Rahman, Chowdhury, & Akhter, 2019;Rahman et al, 2011) and diversity in forest (Chowdhury, Islam, Hafiz, & Islam, 2018;Rahman et al, 2019), but research work on regeneration aspect of forest is not available where Durgapur hill forest lacks information regarding natural regeneration, stocking, and conservation issues. This study will enrich the knowledge of natural regeneration and quantitative distribution of plant species in the case of hill forest which may be useful in providing guidelines for future management of forest.…”

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
