Height-age curves for different forms of the Bertalanffy-Richards height-age model. The solid lines show: (a) National Type A general polymorphic model; (b) Type C Bay of Plenty regional general polymorphic model; (c) Type B model at latitude 400S and elevation 200 m; (d) Type B model at latitude 400S and elevation 20 m (upper line) and 500 m (lower line). In all cases, the dashed line is the Type A anamorphic model and the dotted line is the Type A common-asymptote model. Also in all cases, the upper 3 curves are at SI 38 m and the lower group at SI 22 m.
