ECOPICS_Mx_Aboveground biomass from Pico de Orizaba Protected Park

ECOPICS Project : Aboveground Plant Dry Mass from 0.2 5 x 0.25m soil monolith Field campaign October-November 2017 Last modification : May 2022 by Isabelle Barois and Martín de los Santos The above-ground plant biomass was sampled per species on the top of the monolith (0.25 x 0.25m). Samples were dried in the oven and weighed after by Maricruz Álvarez. All the masses are therefore Dry Masses. The dry biomass of each green species was weighed and recorded independently. The dry biomass of the dry species was weighted all together and only the dominance of each dry species was expressed as a percentage of the total by monolith. The Aboveground Dry Mass Is = total dry green Biomass + total dry Biomass Each monolith has a unique name made of : Altitudinal level : from 3400 to 4400 (every 200 m) Plot Number : from 1 to 30 Target Species names: Tree, <em>Pinus hartwegii</em>; Shrub,<em>Oxylobus arbutifolius/Chianolaena</em> <em>lavandulifolia</em> and; Herb, <em>Lupinus monticola/Senecio roseus</em>.ECOPICS项目：2017年10月至11月野外科考获取的0.25×0.25m土壤柱样（soil monolith）地上植物干重数据集。最后更新时间：2022年5月，由Isabelle Barois与Martín de los Santos完成维护。 研究针对各物种，在土壤柱样顶部的0.25×0.25m区域内采集地上植物生物量样本，样本经Maricruz Álvarez烘箱烘干后称重，所有质量数据均为干重。 每种绿色活体植物的干生物量均单独称重并记录；枯败植物的干生物量则统一合并称重，且仅以各枯败物种在对应土壤柱样总枯败生物量中的占比，来表征其群落优势度。 地上总干重计算公式为：总绿色活体干生物量 + 总枯败干生物量。 每个土壤柱样拥有唯一命名，命名规则如下： 1. 海拔梯度：范围为3400至4400米，间隔200米； 2. 样地编号：取值范围为1至30。 目标物种包括： - 乔木：<em>Pinus hartwegii</em>； - 灌木：<em>Oxylobus arbutifolius</em>与<em>Chianolaena lavandulifolia</em>； - 草本：<em>Lupinus monticola</em>与<em>Senecio roseus</em>。
