Plant allometry at GCE sampling sites 1-10 in October between 2002 and 2020.

The relationship between height and mass (allometry) was measured for plants collected from Georgia Coastal Ecosystems sampling sites 1-10 in October between 2002 and 2020. This dataset includes data from previous allometry measurements (PLT-GCEM-0211b and PLT-GCEM-0711) and data from 2 additional species measured at site 8 in 2020. Shoots or leaves (Juncus) were collected adjacent to permanent plots in each marsh zone by clipping at the soil surface. Dead leaves were removed from shoots. Height, flowering status (Spartina, Typha and Panicum species only), number of leaves (Spartina species and Zizaniopsis), and dry mass were measured for each plant. The allometric relationships determined in this study will allow annual GCE plant monitoring data to be converted from height to mass. This study may be repeated in the future to examine temporal trends in relation to environmental changes.
