Title:

Plant allometry at GCE sampling site 8 in October, 2007

Abstract:

The relationship between height and mass (allometry) was measured for plants collected from Georgia Coastal Ecosystems sampling site 8 in October 2007. This dataset supplements PLT-GCEM-0211b by providing data for 3 rare species that are common only at site 8. Shoots were collected adjacent to permanent plots in appropriate marsh zones by clipping at the soil surface. Height, flowering status (Typha and Panicum species only), 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.
