GCE-LTER Data Set Summary

Accession: PLT-GCEM-1004b GCE Research Theme: Plant Ecology (Monitoring)

Title: Fall 2009 plant monitoring survey -- biomass calculated from shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10
Abstract: The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2009 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. This data set is based on GCE plant monitoring survey data set PLT-GCEM-1004a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b and PLT-GCEM-0812a.
