Abstract
Field observations from six fens in Wisconsin, U.S.A., under varying conditions (pristine to highly degraded) are archived here. Data was collected and lab analyses were performed to determine relationships between soil water regime, floristic quality, and peat hydraulic properties. Concomitant cover-weighted floristic quality index (wFQI) and mean growing season surface soil moisture (SSM_mean) data from 118 plots were collected. Near-surface soil samples were collected from 9 of the same plots and moisture release curves were created in the laboratory using a Decagon Devices HYPROP system. Moisture release curve model parameters were estimated for the van Genuchten model using SWRC Fit (http://swrcfit.sourceforge.net/) and are presented here for the van Genuchten alpha parameter (VGalpha) and saturated volumetric water content (thetaSAT).

Files: SSM_wFQI.csv : concomitant mean growing season surface soil moisture and cover-weighted floristic quality index for 118 fen plots - column 1 (SSM_mean) : surface soil moisture mean growing season [m^3/m^3] - column 2 (wFQI) : cover-weighted floristic quality index for 118 fen plots [-] wFQI_VGalpha_thetaSAT.csv : wFQI for 9 of the 118 fen plots where soil was collected and analyzed in the lab where a moisture release curve was created using a Decagon Devices HYPROP system. Moisture release curve models were fitted using SWRC Fit and van Genuchten alpha parameter and saturated volumetric water content were estimated - column 1 (wFQI) : cover-weighted floristic quality index for 118 fen plots [-] - column 2 (VGalpha) : van Genuchten alpha parameter [1/m] - column 3 (thetaSAT) : saturated volumetric water content [m^3/m^3]
