The capacity of a site to produce specific products (i.e. biomass or lumber volume) for a given vegetative configuration over time as influenced by abiotic factors (i.e. soil, climate, physiography). Net primary productivity (NPP) provides the fundamental measure of site productivity. When measured at the point of leaf carrying capacity for all potential flora, NPP is a measure of potential site productivity. Rate of product growth, an economic component, is occasionally used as a partial measure of site productivity.
