Title: Summer 2007 survey of plant presence and abundance at fifty-five GCE LTER Hammock sites and five GCE marsh monitoring sites
Abstract: Presence and abundance of plant species was determined at the six permanent monitoring transects within fifty-six GCE LTER hammock sites and five GCE LTER study sites in June-July 2007. Plant presence was determined by placing a 1 m x 1 m qaudrat at two meters from the upland border of the study site's permanent monitoring transect and noting all species present. In the center of the quadrat, an additional 0.5 m x 0.5 m qudarat was placed to determine percent cover of each species. Plant height was also measured and recorded that the four corners of the 0.5 m x 0.5 m qudarat.
