Title: Survey of high marsh plant structure and biomass for Spartina, Juncus, Borrichia and Batis specimens on Sapelo Island, Georgia during May to June 2015
Abstract: From May 29th to June 27th of 2015, plant specimens of Spartina, Juncus, Borrichia, and Batis were extracted from Georgia Coastal Ecosystems Study Site 6 and brought to the UGA Marine Institute research center for structural and biomass measurements. The focus of the structural measurements were to capture the top-down horizontal length and branching angles of rhizomes connecting the above-ground plant shoots. The height of plant shoots were also measured, along with the dry-weight mass of all measured plant components. The purpose of these measurements was to provide data that will be the basis for parameter values used in the Virtual Prairie agent-based model for clonal plant growth and competition. Note that a web-based index of plant photographs from this study are available at http://gce-lter.marsci.uga.edu/public/datasets/ancillary/PLT-GCET-1508/.
