Vegetation diversity, structure, composition and carbon stock of community managed forests of Mid-hills Nepal. Asian J For 7: 29-36. Depending on management practices, forests can serve as both carbon sinks and sources. The goal of reducing carbon emissions and increasing the carbon sink is thought to be feasible if carbon reservoirs in current forests are protected and conserved. This study was objectively conducted to assess the vegetation diversity, structure, and carbon stock of the Mid-hills of Nepal. The study was undertaken in the Lanta Community Forest, Jajarkot District, Nepal, which has an extent of 38.65 hectares. Data for vegetation analysis and carbon stock assessment were collected using systematic random sampling using quadrats of 10×10 m with a total number of 35 quadrats. Within each quadrat, individual trees and bamboo were identified in the sites, and their height (m) and DBH (cm) were measured. Density, frequency, basal area, and Important Value Index (IVI) were calculated as structural parameters of vegetation. The Above-Ground Tree Biomass (AGTB) and Below-Ground Tree Biomass (BGTB) were calculated using an allometric equation based on tree diameter, height, and wood-specific gravity. The species diversity, species richness, and evenness were found to be 2.2, 2.35, and 0.83, respectively. A total of 14 tree species, with 723 individuals and one bamboo species were recorded. Rhododendron arboreum Sm. had the highest tree density with 211 trees/ha, while Tsuga dumosa (D.Don) Eichler had the highest IVI. Total wood volume, biomass, and total carbon stock were estimated at 15.37 m3 ha-1, 31.99 t ha-1, and 15.03 t ha-1, respectively. There was a strong negative correlation (r = -0.59) between R. arboreum and R. campanulatum D. Don and a strong positive correlation (r = +0.65) between Malus sikkimensis and Machilus species. For the preservation and sustainable management of community forests, information regarding the structure, composition, and dominance of tree species is provided by the study. The establishment of community forests is thus demonstrated in this article as a means of promoting the protection and preservation of regional biodiversity.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123801011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Floristic composition and structure of closed and open forests in the Banco National Park, Abidjan, Côte d’Ivoire. Asian J For 7: 17-26. Natural ecosystems are pressured to degradation caused by human activities. To develop conservation guidelines for these ecosystems, it was necessary to have enough information on their biodiversity. This study aimed to investigate the species richness, diversity, structure, and composition of vegetation in the Banco National Park (BNP), Abidjan, Côte d’Ivoire, in two forest types, namely closed and open forests. Vegetational data was collected using a sampling plot and itinerant methods. The results showed that 345 and 283 species were recorded in the closed and open forest, respectively, suggesting that the closed forest appears richer than the open forest. Fabaceae, Rubiaceae, and Apocynaceae were the most dominant families in both forest types. Both forest types had a high Shannon-Weaver diversity index and high Pielou equality index. The most important species in the open forest included Chrysophyllum subnudum Baker (Sapotaceae), Allanblackia floribunda Oliv. (Clusiaceae) and Funtumia africana (Benth.) Stapf (Apocynaceae), while in the closed forest were Strombosia pustulata Oliv. (Olacaceae), Turraeanthus africanus (Welw. ex C.DC.) Pellegr. (Meliaceae), and Monodora myristica (Gaertn.) Dunal (Annonaceae). The diametric structure showed the greatest proportion of individuals with low diameter classes, indicating regeneration potential. However, there were great differences in stand structure between the open and the closed forest, especially in high-diameter classes, indicating that the open forest has been pressured by timber cutting. The results of this study can serve as baseline information to develop conservation and rehabilitation strategies in BNP to sustain its biodiversity components.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129376921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of bushfires on animal abundance and diversity across land tenures in Miombo woodlands, Tanzania. Asian J For 6: 43-51. Southern Africa is dominated by Miombo forests (woodlands), the world's largest savanna. The purpose of this research was to examine how bushfires affect mammalian populations in Miombo woodlands under various forest tenure systems. The data was gathered through household questionnaires, a probing question checklist for key informants, participant observation, Participatory Rural Appraisal (PRA) methods, and a field inventory. We enlisted the aid of the local communities in our analysis of the PRA data we collected. Quantitative and qualitative data and information were subjected to content and structural-functional analysis. Quantitative data was examined using Statistical Package for the Social Sciences (SPSS) software. Microsoft Excel was used to examine inventory data on animal stocks. The average number of mammals collected from each forest tenure system was compared using Analysis of Variance (ANOVA) to see if there were statistically significant variations. The variety of mammal species in various forest tenure systems was measured using the Shannon-Wiener Index (H). Based on the findings, agricultural activities (44.5%), charcoal production (21.1%), and wildlife hunting (18.9%) accounted for the vast majority of bushfires in Miombo woods. It was thought that illegal logging and honey collection were the only contributing factors. Mammal populations tend to be most significant in Central Governmental Forest Reserves, then in those of the Local Government, and finally in those of the Village Government. Mildly burned sections in the Central Governmental Forest Reserve had a diversity index of 3.2. In contrast, those in the Local Government Forest Reserve and the Village Forest Reserve had indices of 2.0. There was little difference in the diversity index values of the Central Governmental Forest Reserve (2.0) and the Village Forest Reserve (2.0) for moderately burned blocks and the Local Government Forest Reserve (1.6) for unburned blocks. The Central Governmental Forest Reserve had a diversity value of 1.5 for the severely burned blocks, the Village Governmental Forest Reserve had a value of 1.4, and the Local Government Forest Reserve had a value of 1.2. Like other mammals with a low fire escape rate, bushfires hit the rock hyrax particularly hard. As a result, it is suggested that the current management regimes of Local Government Authorities be strengthened to ensure enhanced local community participation with more effective law enforcement measures to save the woods from deterioration. Similarly, communities should be given access to financing and encouragement to pursue income-generating activities to lessen their reliance on Miombo woodlands.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134150252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives were to examine dendrometric parameters and to analyze tapping characteristics for frankincense production. We randomly distributed 97 sample plots; in each, we counted B. papyrifera trees, measured their diameter at breast height (dbh), total height, bole height, and crown diameter, and examined the correlation between crown diameter and dbh. We examined 116 tapping spots made on 13 randomly selected trees. In each tree, we measured upper and lower tapping heights, calculated potentially untapped bole height, counted the number of tapping spots, measured their dimensions, recorded their directions, and compared mean numbers of tapping spots at four directions using one-way ANOVA (?=0.05). Results revealed that the distributions of dbh and the total height of tapped B. papyrifera followed a bell shape, and that of bole height and crown diameter followed a bell-shaped skewed to the right. Results revealed a significant (P=0.000) correlation between crown diameter and dbh (N=499) that trees were tapped at the four directions without significant difference (P=0.427) between mean numbers of tapping spots at the four directions.

Recycling for deforestation reduction in Tanzania: Why are households not using waste charcoal?. Asian J For 7: 1-8. Charcoal making and the subsequent waste charcoal produced to contribute to deforestation and the production of greenhouse gases, the major drivers for climate change. Whereas climate change is increasingly becoming a public issue, Africa produces 63% of the total global wood charcoal. Since 2004, the demand for wood charcoal on the continent has risen by 30%, the highest in the world. The low efficiency of locally made earth kilns, between 8% and 36%, reported in Africa has contributed to increased waste charcoal production on the continent. However, more information is needed on the cycling use of waste charcoal in low-income countries. In order to improve forest resource use, we investigated the factors influencing the cycling use of wood waste charcoal in the Kilosa District of East-Central Tanzania between 2020 and 2021. A total of 298 randomly selected households were involved in the survey. SPSS version 20 tools were used in the analysis through cross-tab descriptive statistics and the independent sample t-test. Results show that sex, age, expenditure on fuel energy, environment, and technology for cooking significantly affected household use of waste charcoal (p < 0.05). The availability of wastes (v = 0.272) was the most influential factor in the cycling use of waste charcoal. The paper shows that cycling the use of wood waste charcoal would reduce volumes of trees cleared for firewood and improve sanitation by removing rampantly disposed waste from the environment.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124807374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We, therefore, assessed the stand structure, biomass accumulation, carbon storage, and their changing patterns with age in Eucalyptus camaldulensis Dehnh. plantations in the northern part of Bangladesh in early 2021. Biomass and carbon stocks were estimated using the allometric models specific for E. camaldulensis from the biophysical tree parameters (i.e., height and DBH). We used the data from 45 sample plots (100 sq. m each) covering different age classes such as 2, 5, 7, 8, 11, 13, and 21 years. The aboveground, belowground, total biomass, and carbon significantly varied between stand ages (p<0.05). The highest aboveground, belowground, and total carbon stocks were observed at 21 years, and the lowest was found at two years. We observed a positive and strong relationship between total carbon and stand variables such as stand height, diameter at breast height, basal area, crown width, crown length, and bole height but a negative relationship with density. The mean annual increment of both biomass and carbon increased sharply up to seven years and then decreased. Despite having some ecological constraints, E. camaldulensis accumulate a large amount of carbon from the atmosphere, perhaps aiding climate change mitigation.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121205825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vertical distribution of soil properties and soil organic carbon in community managed forest of Siwalik Hill, Nepal. Asian J For 6: 91-96. Nepal's Community Forestry (CF) approach is globally recognized as an innovative and successful approach to forest resource management. Shorea robusta Gaertn. is the dominant tree species of Nepal's forest which covers 19.28% of the total stem volume of the country's forest area. Soil represents a significant terrestrial Carbon (C) pool and can play a significant role in mitigating global warming. Therefore, analyzing soil physicochemical properties and Soil Organic Carbon (SOC) stock is essential because they are key parameters for evaluating land use management systems. The present study was conducted in the Durga Mai Community Forest (DMCF) of Makawanpur District, Nepal, to assess the vertical distribution of soil physicochemical properties and SOC stock. Soil samples within a 1 m profile in five depth layers (0-20 cm, 21-40 cm, 41-60 cm, 61-80cm, and 81-100 cm) were collected and analyzed for Bulk Density (BD), soil texture, soil pH, soil carbon content, Total Nitrogen (TN), Available Phosphorous (AP), Available Potassium (AK) and SOC stock. Sandy loam was the dominant soil textural class reported throughout the study area. Average BD, soil pH, TN, AP, and AK in the S. robusta forest's soil in 1 m soil profile depth were found to be 1.16 ±0.07 gmcm-3, 5.78 ±0.62, 0.14 ±0.04 %, 5.94 ±1.04 kgha-1, and 104.20 ±19.66 kgha-1, respectively. The results estimated 107.57 ±3.06 tha-1 of SOC stock in 1 m soil profile, with 0.93 ±0.21% average SOC content. Further, average TN, AP, and AK were found to be decreased with an increase in soil profile depths.

Biadgligne A, Gobezie T, Mohammed A, Feleke E. 2022. Estimation of carbon stock and emission of community forests in Eastern Amhara, Ethiopia. Asian J For 6: 74-82. Carbon emission resulting from deforestation and forest degradation contributes to climate change. Halting deforestation is, therefore, one strategy to mitigate the changing climate. As the global carbon market develops, an opportunity to halt deforestation can be contributed by community forests as a win-win solution for climate change mitigation and livelihood provision, yet knowing the carbon stock of the forest is important to enhance the bargaining power of the community to get carbon finance. Thus, a case study was conducted to quantify carbon stocks and emissions from three community forests (i.e., Asha-Guba, Jemely, and Beshilo) in Eastern Amhara, Ethiopia. Stratified systematic sample quadrate methods were used, and a total of 57 equally spaced nested square quadrats were laid for the measurement of carbon density. Carbon pools, including above-ground living biomass, dead wood, surface litter, belowground root biomass, soil organic carbon, and harvested wood product, were accounted for the estimation of site-level carbon density (t ha-1) and carbon dioxide equivalent (CO2e) emission. There was high variability in the estimated mean carbon density and CO2e emission across the three community forests. The highest carbon density was recorded in the Asha-Guba community forest with 124.27 ± 8.29 t ha-1, followed by Jemely and Beshilo forests with 91.24 ± 3.18 t ha-1 and 73.55 ± 3.13 t ha-1, respectively. The largest proportion (59-63%) of carbon was stored in the soil pool, followed by the above-ground biomass (27-32%), while that in dead organic matter was insignificant. The community forests currently stored total carbon stocks of 57,612.14 ± 13.81ton (210,860.43 CO2e). To ensure the sustainable management of the forests, long-term finance and investment must be introduced urgently.","PeriodicalId":115036,"journal":{"name":"Asian Journal of Forestry","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131842501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
