This dataset includes tables used in a study of periwinkle snail (Littoraria irrorata) association with big cordgrass (Spartina cynosuroides) and smooth cordgrass (Spartina alterniflora) in a salt marsh along the York River. The overarching goal of this study was to assess if and how plant palatability, predation pressure, and environmental characteristics of each Spartina species influenced the densities and grazing of periwinkle snails. The data were collected in support of a study authored by Failon, Wittyngham, and Johnson in 2020 titled Ecological Associations of Littoraria irrorata with Spartina cynosuroides and Spartina alterniflora. It was published in the journal Wetlands.
