ABoVE: Characterization of Burned and Unburned Boreal Forest Stands, SK, Canada, 2016

This dataset provides the results of field measurements and estimates of carbon stocks and combustion rates that characterize burned and unburned southern boreal forest stands near the La Ronge and Weyakwin communities in central Saskatchewan (SK), Canada. Measurements were completed in 2016 at 47 stands that burned in the 2015 Saskatchewan wildfires (Egg, Philion, and Brady) and at 32 unburned stands in comparable adjacent areas. Stands were characterized through field observations and sampling of the vegetative community (i.e., tree species, abundance, and biophysical measurements, stand age, coarse woody debris, history of fires or logging), soils (i.e., soil moisture class, unburned and burned soil organic layer depth, samples for bulk density and carbon analyses), and basic landscape geophysical traits. From these results, the pre-fire carbon stocks and carbon combustion values from both the above- and below-ground pools were estimated using a combination of linear and mixed-effects modeling and were calibrated against carbons stocks from the unburned stands. Estimates of uncertainty were generated for above- and below-ground carbon stocks and combustion values using a Monte Carlo framework paired with classic uncertainty propagation techniques.

本数据集提供了对加拿大萨斯喀彻温省（SK）中部拉荣和韦亚金社区附近南部北方森林中已燃烧和未燃烧林地的实地测量结果以及碳储量和燃烧速率的估算。这些测量于2016年在2015年萨斯喀彻温省野火（Egg, Philion, 和 Brady）中遭受火灾的47个林地以及32个相邻未燃烧林地完成。林地特征通过实地观测和植被群落（即树木种类、丰度及生物物理测量、林龄、粗木质残留物、火灾或采伐历史）的采样、土壤（即土壤湿度等级、未燃烧和燃烧土壤有机层深度、用于体积密度和碳分析的样品）以及基本的景观地球物理特征来表征。基于这些结果，利用线性混合效应模型结合大语言模型，对火灾前地上和地下碳储量和燃烧值进行了估算，并通过未燃烧林地的碳储量进行校准。采用蒙特卡洛框架配合经典不确定性传播技术，对地上和地下碳储量和燃烧值的不确定性进行了估算。
