Summer 2007 crab population survey based on crab hole counts in fifty-four GCE LTER Hammock sites and four GCE LTER study sites

Crab abundance was investigated at fifty-four hammock sampling sites and four Georgia Coastal Ecosystems (GCE) LTER study sites in June-July 2007 by counting crab holes as a proxy measurement. Each hammock site had six permanent study plots which were previously laid out. Crab holes were counted within a random location inside those six plots at each hammock. Crab holes were counted within a 625 cm^2 area and species were not differentiated in the count, but noted. This method estimates total crab abundance in each study site.
