The spreadsheet file contains the data presented in a study that assessed the impacts of the invasive vine Antigonon leptopus (referred to as ‘Coralita’) on plant communities within the lowland ecosystems of the Caribbean island of St. Eustatius. These impacts were studied using a paired plot design, with the plant community composition in each plot invaded by Coralita being contrasted with an uninvaded plot in close proximity. In total, 17 plot pairs were considered. The dataset contains observations of plant community composition in full plots of 10 m by 10 m, and, for a subset of 14 plots, observations of plant community composition in 2 m by 2 m subplots. The field survey to collect these data was undertaken in November and December of 2018. Contact: Martin Wassen - M.J.Wassen@uu.nl
