The task of replacing species after cutting is being solved; i.e., in what proportions (in area or composition) can available species regenerate themselves from the place where a particular mature species was destroyed (cut)? Formally, this is about finding elements of the so-called regeneration matrix, which has N2 elements at N species. Appropriate balance equations are derived, where the number of unknowns (N2) is more than the number of equations (N); therefore, the task can be solved only with the adoption of additional (formal or expert) limits; a probable variant for formal limits is proposed. As a result, the universal analytical algorithm occurs to make solutions possible with any number of involving species. The required initial data are areas occupied the mature and juvenile stands (for each species). The supposed approach can be adapted to solving an analogous task in the case of a stand destroyed in a fire.
