Even if a stand starts with an initial density far below the full density, mortality occurs in accordance with an increase in biomass as the stand develops. Eventually, the time-trajectory of biomass and density asymptotically approaches a straight line on logarithmic coordinates. The features of the time-trajectory of biomass and density were translated into a mathematical formula, which was in turn transformed into a model for describing the time-trajectory of mean phytomass and density. The usefulness of the models was verified in describing the time-trajectory of biomass (or mean phytomass) and density throughout the development of eastern white pine (Pinus strobus) stands. Another model for describing the time-trajectory of mean phytomass and biomass was derived by eliminating density from the mathematical formula. The applicability of the derived model was also examined for the eastern white pine stands.
