“…Hence, the need to manage all forests more sustainably including the catchment forest reserves is emphasized. A better understanding of carbon stocks in these forests is important for estimating national carbon losses from deforestation and forest degradation (Willcock et al 2014;Karki et al 2017;Kendie et al 2021).…”

Abstract. Mwaluseke ML, Mwakalukwa EE, Maliondo SMS. 2023. Vegetation composition, diversity, stand structure and carbon stock of a dry evergreen montane forest of Lendikinya forest reserve in Tanzania. Biodiversitas 24: 551-562. There is limited information on woody plant diversity and vegetation patterns in African dry forests, particularly in East Africa, and hence increasing the interests in understanding species composition, diversity, and structural attributes of catchment forest reserves found in Tanzania. Moreover, tree species composition, species richness, and carbon stock are not well documented in most montane forests in the region, apart from Ethiopia. Their potential in terms of carbon storage is also important for understanding their productivity and the extent to which they can be used in mitigating the effects of climate change. This study assessed vegetation composition and diversity, stand structure and potential carbon stocks of Lendikinya Forest Reserve, a dry evergreen montane forest located in Monduli District in Tanzania. A total of 56 concentric circular plots with subplots of 2 m, 5 m, 10 m, 15 m and 20 m radii were used to collect woody species data on standing trees and stumps across the entire forest of 3,689 ha. A total of 79 species belonging to 36 families were identified. Drypetes natalensis (9.2%), Diospyros abyssinica (7.1%) and Dombeya rotundifolia (6.5%) were the most important species as per the Importance Value Index (IVI). The diversity indices have indicated the forest reserve to have a high diversity of woody species. Stand structure comprises 1,398 ± 679 stems ha-1, basal area of 11.42 ± 5.41 m2ha-1and standing volume of 54.47 ± 24.1 m3ha-1 while the mean carbon stocks were 16.04 ± 7.7 t C ha-1. The alarming disturbances stress the urgent need for increased conservation efforts in order to protect the existing biodiversity and increase carbon storage and enhance water conservation in the reserve.

“…It is imperative to stop additional deforestation for this reason. According to Karki et al (2017), deforestation prevention has been generally accepted as a promising mitigation strategy for mitigating climate change through carbon negotiation mechanisms like REDD+ (reduced emission from deforestation and forest degradation, plus forest conservation, sustainable forest management, and enhancement). REDD+ was devised under the United Nations Framework Convention on Climate Change (UNFCCC) to combat CO2 emissions (Houghton 2012;Daba et al 2022).…”

Abstract. Mwakalukwa EE, Mwakisu A, Maliondo SMS. 2023. Woody species diversity, composition, structure and carbon storage of a dry evergreen montane forest of Essimingor Nature Forest Reserve in Tanzania. Intl J Trop Drylands 7: 26-36. The biodiversity status of flora and fauna of many forests found on small protruding and isolated hills in most parts of dry areas in Tanzania is largely less studied. Their contribution to climate mitigation options also remains largely unknown. This study assessed the woody species diversity, composition, structure and carbon stocks potential of a dry evergreen montane forest of Essimingor Nature Forest Reserve in Tanzania. The vegetation data were collected from 23 concentric sample plots of 5m, 15m, and 20m radius laid systematically across the entire forest area of 6,100 ha. A total of 54 trees and shrubs species belonging to 29 families were identified. Diversity indices indicated the forest to have a high diversity of woody species. The most important species were Cassipourea malosana, Diospyros abyssinica and Drypetes natalensis. Stand structure comprised 288±173 stems ha-1, basal area of 11.47±7.23 m2ha-1 and standing volume of 27.3±16.3 m3ha-1. The mean above-ground and below-ground carbon stocks were 56.93±34.60 Mg C ha-1 and 34.71±19.72 Mg C ha-1, respectively. The observed high species diversity and carbon density signify the importance of conservation efforts bestowed in this reserve. Quantification of other carbon pools for estimation of the total carbon stock potential of this forest is recommended.

“…Thus, today's forest ecosystem has the challenge of devising effective strategies and techniques for enhancing forest regeneration conditions and restoring abandoned areas (Chand et al, 2018). Deforestation prevention is, therefore, a generally acknowledged acceptable mitigation strategy for mitigating climate change in the short term (Karki et al 2017), and it is gaining traction across scientific communities and carbon negotiation mechanisms like REDD+ (reduced emissions from deforestation and forest degradation).…”

“…Research has shown the impact of the devolved management of forests in Nepal as a representative picture of forest regeneration and conservation (Sharma et al, 2020;Joshi, 2021). The existence of distinct age groups of seedlings, saplings, and trees characterizes a forest's regeneration and production capacity (Karki et al, 2017), which subsequently aids in understanding the state of tree communities, regeneration, and variety for conservation purposes (Chazdon et al 2020). Environmental variables, soil quality, human pressures, and management techniques influence species regeneration.…”

Abstract. Rawal K, Subedi PB. 2022. Vegetation structure and carbon stock potential in the community-managed forest of the Mid-Western Hilly Region, Nepal. Asian J For 6: 15-21. Community forests (CF) play a crucial role in sustainable development and accumulate carbon to mitigate global climate change. The objective of this study was to evaluate the plant diversity, regeneration status, and carbon stock potential of two community-managed Shorea robusta-dominated forests in Nepal's Dailekh District, namely Bayeldhunga Pahapu CF and Bayeldhunga CF. A total of 76 sample plots were studied using a systematic sampling intensity of 0.5%. The density of species in the developmental phase was used to determine the forest's regeneration condition. Allometric equations were used to calculate the aboveground carbon store of tree species. Shorea robusta Gaertn. was the foremost species regarding regeneration and carbon storage in the studied forest areas, with high regeneration conditions. The seedlings, saplings, and trees in the Bayeldhunga Pahapu CF exceeded those in the Bayeldhunga CF. In both study areas, J-shaped reverse population curves were observed. This study provided details on tree species' regeneration condition, structure, proportions, and carbon sequestration capacity, which is critical for community forest management and conservation. The analysis showed that by altering the structure and proportions of community forests, community management has boosted the carbon storage of forests and enhanced forest productivity.
