Presuming "withaut after-effect" development in homogeneous, evenaged stands (tree growth), can bei described by the formal stand parameters α, β, γ an the Kologorow-Suzuki differentail equation - (1.1.4). Apparently the fluctuation of trees around the mean doesn't violate rank status, demanding the same from the realisations of the modells used. A useful criterium for this purpose is the correlation function. Neglecting mortality, tree growth can be represented by a differential equation equivalent to the Suzuki-modells.The solution parameters EXt and R (t) can be obtained in a transparent way. Two modells of stochastic differential equation are discussed, the second is illustrated on plotting pictures.
