Fall 2011 plant monitoring survey -- biomass calculated from shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10

The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2011 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002 and October 2008. Biomass was only calculated for dominant species, including Spartina alterniflora, S. cynosuroides, Juncus roemerianus, and Zizaniopsis miliacea, as well as rarer species including Scirpus spp, Panicum spp. and Typha angustifolia. This data set is based on GCE plant monitoring survey data set PLT-GCEM-1112a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b, PLT-GCEM-0711, and PLT-GCEM-2011.

2011年10月，在GCE LTER的10个采样点永久样地中调查的植物生物量，基于2002年10月和2008年10月针对各采样点、区域及物种推导得出的生物量与株高、开花状态间的异速生长关系（allometric relationships）估算得出。生物量仅针对优势物种（包括Spartina alterniflora、S. cynosuroides、Juncus roemerianus及Zizaniopsis miliacea）和稀有物种（包括Scirpus spp.、Panicum spp.与Typha angustifolia）进行计算。本数据集以GCE植物监测调查数据集PLT-GCEM-1112a为基础，而异速生长关系则来源于GCE数据集PLT-GCEM-0211b、PLT-GCEM-0711及PLT-GCEM-2011。
