Full description
There are presence absence records for vegetation and matched hydrological data from 687 1 x 1-m quadrats recorded from 11 wetlands and wetland complexes (28 sampled hydrological gradients referred to as transects) across the upper and lower South East of South Australia. Plant data were collected in spring 2013.Hydrological monitoring data at each site consisted of continuous (6 hourly) surface water level data from a state agency monitoring network. Observed water levels at the monitoring instrument on the day of monitoring were related to the observed depth of water at each quadrat, assuming a flat, level water surface and obtain a datum for each quadrat relative to the monitoring instrument.
The continuous monitoring record was then used to calculate a range of different hydrological predictors indicating the variation at each quadrat. The hydrological dataset provided are the univariate summary statistics recording different aspects of surface water dynamics for each quadrat. Hydrological predictors (sum-exceedance value, hydroperiod and maximum inundation depth) were calculated for annual and seasonal periods in the three-years prior to plant data collection. See metadata and relevant publication for additional details on calculation.
Hydrological predictors for each quadrat are provided in a single matrix of sites by predictors, with relevant location details for the quadrat (xy coordinates, site, transect). Included is a single electrical conductivity class for each transect (ordinal variable - low moderate, high - see metadata).
Vegetation data are provided as a single matrix (quadrats x plant functional group) showing presence absence of each functional group in each quadrat. There is also a lookup table giving the assignment of each plant species to a plant functional group.

Spatial Coverage And Location
text: We surveyed wetlands located across much of the South East NRM region. The geographical extent is smaller than this because the location of the wetlands was not along the periphery of the region. We estimate the study extent at 9600 km^2 (based on the area of a convex hull enclosing all wetlands).
