Abstract. Ghimire P, Lamichhane U. 2020. Plant species diversity and crown cover response to regeneration composition in community-managed forest. Asian J For 5: 36-41. The study was carried out to assess plant species diversity and crown cover response to regeneration composition in Nawalpur Saraswati (Basamadi) Community Forest of Hetauda Municipality of Makawanpur District, Nepal in November 2020 to December 2020. A stratified random sampling method with a total of 94 sample plots was laid out for the study. Altogether 44 species belonging to 26 families were recorded in the study site, of which 23 species were represented in tree category, 14 in shrub, and 7 in herb category. Both Shannon Weiner and Simpson's diversity index indicated good floral species diversity in the study area. The forest was dominated by Shorea robusta with 396 stem ha-1, followed by Terminalia bellerica 29 stem ha-1, Lagerstroemia parviflora 25 stem ha-1, and Terminalia tomentosa (syn. Terminalia elliptica) 21 stem ha-1 respectively. Both seedling and sapling were found in good number with seedlings 11,583 number ha-1and for seedlings it was recorded 1,896 number ha-1. Both seedling and sapling density was recorded higher in open crown coverage (seedlings=32625 number ha-1; saplings=5033 number ha-1) than in close crown coverage (seedlings=13,708 number ha-1; saplings=2,550 number ha-1). Therefore, the study concluded that crown opening facilitates growth and development of regeneration density in Shorea robusta and its associated forests. Furthermore, the information generated could be useful to predict future trends in species composition and stand structure in order to optimize the possible forest management strategies.

The Sal (Shorea robusta) dominated forest vegetation of Dalma Wildlife Sanctuary, West Singhbhum, Jharkhand, India was explored to evaluate the diversity and vegetation structure through different phyto-sociological attributes. The knowledge of the structure and composition of the plant communities has enormous significance in conservation of managed forests, therefore, the plant species diversity, structure and importance value index (IVI) at various levels, viz., trees, shrubs and herbs were studied. A total of 153 plant species (66 trees, 30 shrubs and 57 herbs) belonging to 124 genera of 51 families were recorded from the 30 random plots marked for sampling within the sanctuary. The IVI was highest in Shorea robusta (40.87) and lowest in Syzygium salicifolium (1.08). Shannon-Weaver’s diversity index was recorded highest in herbaceous species (3.66) than in trees (3.08) and shrubs (2.66). Simpson’s index was highest in trees (0.106) than in shrubs (0.035) and herbs (0.028). Pielou’s index was found highest in herbs (0.064) than in shrubs (0.048) and trees (0.046) which was within the range reported for different Indian forests and also which indicates that the sanctuary exhibits species diverse forest. The result of plant species diversity and their quantitative features reveal that the overall community is heterogeneous.

Scientific forest management is an emerging need for managing existing natural forests of Nepal on the basis of silvicultural intervention. The study was carried out in Lumbini Collaborative Forest at Rupandehi District of Nepal, where Sal (Shorea robusta) forests are being managed under Irregular Shelterwood System with eighty years of cutting cycle since 2011–2012. The study was purposed to find out the intial effects of silvicultural intervention on plant species diversity and regeneration of Sal forest. The vegetative sampling was done using quadrate method based on the principle of simple random sampling both in the managed as well as the unmanaged parts of forest. The study found out remarkable increase in regeneration as well as decrease in plant diversity in the managed first and second-year stands (Block I and Block II respectively) as compared to the unmanaged stand (Block III) at its initial level of implementation. The mean value of diversity, richness, evenness, dominance index and regeneration of S. robusta varied significantly (p?0.05) between the managed blocks (stands). The seedling density of S. robusta was found higher in the managed blocks (Block I and Block II) as compared to the unmanaged one (Block III) in terms of height class. The study recommends implementation of Irregular Shelterwood System for managing the existing degraded Sal forests of the Terai region of Nepal, however, its long term effects on plant species diversity should be further studied in detail.Banko Janakari, A Journal of Forestry Information for NepalVol. 25, No. 1Page: 20-29

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.

AbstractA total of 176 homestead forests at three altitudes in the Chittagong Hill Tracts, Bangladesh were randomly surveyed to estimate carbon (C) stocks and how stand structure affects the biomass C. All woody vegetations were measured, and litter and soil (0–30 cm depth) were sampled. The tree biomass C stock in the top two altitude forests was up to 37–48% higher than in low altitude, owing to significantly higher tree density and species diversity. An increase in species diversity index by one unit increased the biomass stock by 23 Mg C ha−1. The C stock of litterfall in low altitude forests was 22–28% higher than in the top two altitude due to the deposition of litters downslope and deliberate use of mulch for soil improvement and conservation, resulting in up to 5% higher total soil C. The topsoil C was 10–25% higher than the deeper soil, depending on the altitude. The forest stored 89 Mg C ha−1, indicating a potential for C sequestration in trees outside forest. This study would help policymakers to strengthen the recognition of small-scale forests for mitigation in REDD + (reducing emissions from deforestation and forest degradation, the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks) and support owners through C credits from sustainably managed forests.
