Appendix A. Model documentation of carbon sequestration in litterfall without climate and flooding parameters.
Formula: Carbon sequestration in litterfall ~ Distance to low groundwater table (LALW) * Tree species + (1 | Site/Year)
AIC = 1109.0; BIC = 1138.9; logLik = -544.5; deviance = 1089.0; df.resid = 137
Scaled residuals: Min = -3.3548; 1Q = -0.3489; Median = -0.0207; 3Q = 0.2680; Max = 1.5009
