Richards Growth Curve
Richards Growth Curve
The Richards growth curve is often applied to fit empirical data on forest growth. However, the parameters of the Richards growth function are not easy to interpret in forest management terms. This graph allows interpretation of a Richards curve (red) in terms of site productivity and "rejuvenation bias"—a parameter of a 4/5 law model characterizing the effects of intensive thinning or delayed development at a early stage of growth.
