Above ground plant biomass, canopy height and estimated percent cover supporting marsh and subtidal benthic community and marsh invertebrate distribution studies in paired oiled/unoiled sites in coastal Louisiana in Spring and Fall 2013

Plant data were collected in Spring and Fall 2013 in paired oiled/unoiled sites in three regions of coastal Louisiana. Live and dead plant biomass for individual species, total living and dead plant biomass per site, canopy height, and estimated percent cover were measured in quadrats placed 1 and 10 m from the marsh edge at three transects perpendicular to shore at each site. Sites were sampled once in the spring (April and May) and once in the Fall (October, November, and December). This dataset coincides with benthic infauna and mussel and snail collections to determine those factors most important in influencing benthic communities and intertidal marsh invertebrate distributions.
