Abstract

The present study was accomplished to assess and compare tree diversity, carbon stock, and to find the relationship between carbon stock and tree diversity in scientifically and conventionally managed community forests (CFs) of Kanchanpur District, Nepal. A total of 94 sample plots were overlaid with a systematic random sampling method (51 plots in scientifically managed Singhapur CF and 43 plots were established in conventionally managed Kalika CF). The height and DBH of each tree were measured to calculate biomass and carbon stock. Shannon-Wiener and Simpson’s indexes were calculated for tree diversity. The data were pooled and analyzed using MS Excel and SPSS software. The values were statistically compared using a t-test. The total carbon stock and tree diversity were higher in scientifically managed CF (207.58 tons/ha and H= 0.97) than conventionally managed CF (183.72 tons/ha and H=0.85). Shorea robusta has a major contribution on total carbon stock in both CFs (Kalika: 66.34% and Singhapur: 70.43%) followed by Terminalia tomentosa (Kalika: 24.65% and Singhapur: 13.36%). The t-test did not show any significant difference for the mean values of carbon stocks and tree diversity between the CFs at a 5% level of significance. However, carbon stock showed a weak but positive relationship with species richness and negative with evenness. The result of the study recommends managing forests scientifically for increased tree diversity leading to enhanced carbon deposition.
尼泊尔坎昌布尔地区科学管理和常规管理社区森林碳储量和树木多样性的比较研究
本研究旨在评估和比较尼泊尔坎昌布尔区科学和常规管理的社区森林中的树木多样性、碳储量,并找出碳储量与树木多样性之间的关系。用系统随机抽样方法覆盖了总共94个样地(科学管理的Singhapur CF中有51个样地,传统管理的Kalika CF中有43个样地)。测量每棵树的高度和DBH,以计算生物量和碳储量。计算了Shannon Wiener和Simpson的树木多样性指数。使用MS Excel和SPSS软件对数据进行汇总和分析。使用t检验对这些值进行统计学比较。科学管理CF的总碳储量和树木多样性(207.58吨/公顷,H=0.97)高于传统管理CF(183.72吨/公顷和H=0.85CF之间碳储量和树木多样性平均值的差异在5%的显著性水平上。碳储量与物种丰富度呈弱正相关,与均匀度呈负相关。研究结果建议科学管理森林,以增加树木多样性,从而增加碳沉积。

期刊介绍: The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
