Table 1.

Parameter estimates and their standard errors from the global linear model for the effect of centered and standardized predictors on floodplain tree cover. CWB, climatic water balance; % sand, soil percent sand. Main effects are ordered from greatest to least variable importance in the global random forest model. All parameters were significant (p < 0.05), except slope and the CWB:slope interaction (marginally significant) in Gorongosa.
