Appendix I. Model documentation of carbon sequestration in aboveground woody biomass including climate and flooding parameters.
Formula: Carbon sequestration in aboveground woody biomass ~ Distance to low groundwater table (LALW) + Tree species + Danube River water level between mean and 10-yearly river water level during the current growing season (MWHWS10GS) + (1 | Site/Year)
AIC = 1108.6; BIC = 1132.4; logLik = -546.3; deviance = 1092.6; df.resid = 137
Scaled residuals: Min = -2.06684; 1Q = -0.23818; Median = 0.00062; 3Q = 0.16248; Max = 1.24527
