  1. Wetland type (Type), latitudinal location (Latitude; Decimal Degrees), number of surveyed plant communities (Nbr. Comm.), mean annual temperature (Temperature; °C), mean total annual precipitation (Precipitation; mm), soil pH (Soil pH; Mean ± Sd), soil moisture (Soil moisture; %, Mean ± Sd), green-up date (Green-up, day of year, Mean ± Sd), green-down date (Green-down, day of year, Mean ± Sd), growing season length (GSL; number of days elapsed between Green-up and Green-down dates, Mean ± Sd). Mean and Sd values for soil pH and soil moisture were calculated from four measures taken once (August 2015) in each plant community. Mean and Sd values for green-up, green-down dates and growing season length were calculated across all communities within each landscape over the period 2013–2016
