GCE - Mollusc pop. Abun. monitoring: Spring 2002 mid-marsh and creekbank infaunal and epifaunal mollusc abun. based on collect from GCE marsh, monit. sites 1-10

Species abundance was determined by hand-collecting all the infaunal and epifaunal molluscs from within quadrats of known area in mid-marsh and creekbank zones (n = 4 quadrats per zone) at all sites. The molluscs were returned to the lab, fixed in formalin, transferred to and preserved in ethanol, counted and measured (size data is reported separately).

The counts were converted to number per square meter. Gastropod species are listed first, followed by bivalve species. Size distribution data for these collections may be found in the GCE-LTER data set INV-GCEM-0412a2.
