Accurate estimates of forest site productivity are an essential part management. Only a few approaches exist for estimating natural uneven-aged forests. This study compared two approaches: dominant height (DH)–dominant diameter (DD) modelling and DH–stand age (A) in terms their prediction accuracy productivity. We developed the models based on both algebraic difference approach (ADA) ADA with mixed-effects modelling. Data originated from four sets continuous measurements Mongolian Oak (Quercus mongolica Fisch.) Korean Larch (Larix olgensis Henry.) northeastern China. The leave-one-out cross-validation was applied to evaluate models. results showed that accuracies DH–DD were significantly higher than DH–A inclusion block-level random effects increased Compared models, did not require which is time-consuming difficult, but DD DH available routine inventories compatible existing inventory data. Therefore, nonlinear recommended estimate
