Long-term research program carried out on permanent experimental plots led to the development of local reference model of unthinned Scots pine stands (PINUS ZIELONKA). On the basis of appropriately selected, in terms of quantity and quality of empirical material was selected the equations of regression. In the case of stochastic dependence, when the value of the dependent variable are subject to random errors, the matching function uses the method of least squares. The final choice of functions and algorithms guided by the size of the coefficients of determination and secondary error rates. The developed growth model can be used to estimate overground biomass and carbon sequestration of unthinned Scots pine stands in the Forest Experimental Station Murowana Goślina.
