Net primary productivity (NPP)

Net primary productivity (NPP)

Net carbon assimilation by plants. NPP = GPP - respiration losses. NPP can be estimated for a given time period as ΔB + L + H, where ΔB = biomass accumulation for the period, L = biomass of material produced in the period and shed (i.e. foliage, flowers, branches), and H = biomass produced in the period and consumed by animals and insects.
