Species occurrence and environmental data from Sullivan et al "Is saltmarsh restoration success constrained by matching natural environments or altered succession? A test using niche models"

Quadrat data used in statistical analysis. Columns are quadrat ID, region (Essex, Norfolk or Humber), marsh age (MR = managed realignment, AR = accidental realignment, NAT = natural reference), redox potential (mV), relative tidal height, then the presence (1) or absence (0) of each study species. Species abbreviations are as used in the paper. Note that one site (FHOLME, quadrat IDs FHOLME 1 to FHOLME 50) was excluded from the final analysis as it was subject to historic grazing.
