Savanna plant and soil carbon data from different burn seasons and histories across Mole National Park, Ghana

Aboveground plant pool and belowground (soil plus root) carbon data for a space-for-time substitution survey of different burn seasons and histories across Mole National Park, Ghana. Carbon data was collected to determine the impact of unintentional late growing season wildfires on carbon storage in a protected area dominated by early growing season prescribed burning land management. The methodology and findings from the study are detailed in the below publication: Awuah J, Smith SW, Speed JDM, Graae BJ. 2022. Can seasonal fire management reduce the risk of carbon loss from wildfires in a protected Guinea savanna? Ecosphere, e4283. https://doi. 88 org/10.1002/ecs2.4283 This data repository contains the following data (and descriptive metadata): (1) Study_site_coordinates: locations for 28 sites surveyed in 2016 as part of an ecosystem carbon stock assessment (2) Aboveground_carbon: aboveground tree, shrub, herbaceous vegetation, deadwood and litter carbon stocks estimated from either destructive biomass sampling or allometric equations. Aboveground carbon data are presented per site. (3) LOI_to_carbon_conversion: a subset of soil samples were analysed for both loss on ignition (LOI) and automated dry combustion using an elemental analyser, the latter more accurate for carbon determination and used to correct LOI values. (4) Belowground_carbon: combined soil and root carbon collected collected to a maximum depth of 17 cm, and split into four soil layers (0-2 cm, 2-7 cm, 7-12 cm and 12-17 cm). MCD14DL MODIS Active Fire Detections data used to defined different burn seasons and histories for sites has not been uploaded and is freely available from online sources detailed in the journal article.本数据集涵盖加纳莫莱国家公园内，针对不同火烧季与火烧历史开展的空间代时间替代法（space-for-time substitution）调查所获取的地上植物碳库与地下（土壤+根系）碳数据。本次碳数据采集工作旨在探究非计划性生长季后期野火，对以生长季早期计划性火烧为主要土地管理方式的保护区内碳储量的影响。 本研究的方法与研究结果详见下述文献：Awuah J、Smith SW、Speed JDM、Graae BJ. 2022. 季节性火烧管理能否降低几内亚稀树草原保护区内野火引发的碳损失风险？《生态圈（Ecosphere）》，e4283. https://doi.org/10.1002/ecs2.4283。 本数据集包含以下内容及描述性元数据： 1. 样地坐标（Study_site_coordinates）：2016年生态系统碳储量评估中调查的28个样地的位置信息 2. 地上碳储量（Aboveground_carbon）：通过破坏性生物量采样或异速生长方程（allometric equations）估算得到的乔木、灌木、草本植被、枯木以及凋落物的地上碳储量，数据按样地呈现 3. 烧失量-碳转换系数（LOI_to_carbon_conversion）：选取部分土壤样品同时开展烧失量（loss on ignition, LOI）与元素分析仪自动干式燃烧法分析，其中干式燃烧法的碳测定结果更为精准，被用于校正烧失量测定值 4. 地下碳储量（Belowground_carbon）：采集至最大深度17 cm的土壤与根系混合碳样品，按4个土层分层（0~2 cm、2~7 cm、7~12 cm及12~17 cm） 用于界定样地火烧季与火烧历史的MCD14DL MODIS主动火点探测数据（MCD14DL MODIS Active Fire Detections）未上传至本数据集，可通过论文中提及的在线渠道免费获取。
