Appendix H. Model documentation of carbon sequestration in aboveground woody biomass without climate and flooding parameters.
Formula: Carbon sequestration in aboveground woody biomass ~ Distance to low groundwater level (LALW) + Tree species + (1 | Site/Year)
AIC = 1110.6; BIC = 1131.4; logLik = -548.3; deviance = 1096.6; df.resid = 138
Scaled residuals: Min = -2.07130; 1Q = -0.25876; Median = -0.00586; 3Q = 0.19171; Max = 1.27238
