This data set includes vegetation response data from two salt marshes in Buzzards Bay, Massachusetts, which received hydrologic restoration to address interior ponding using runnels. These data are from a replicated BACI (before-after-control-impact) designed study. Data were collected using point-intercept method for percent cover, stem counts, stem height measurements, among other vegetation parameters. Field work methods from 2020 to 2023 were standardized and the data underwent quality control checks.
