This paper introduces program SB-CORSICA, for the supporting of the forestry of even-aged and uneven-aged stands of Corsican pine (Pinus nigra ssp. laricio ). The program, that applies the theoretical findings of the author, is written in BASIC, and it has two subprograms: a) simulator SB-CORSO; b) subprogram SB-CORSICANA. The structure of the text reflects the structure of the program. In the first part, the author accomplishes the following: a) establishes the allometric equations for the biomasses of the tree components; b) he characterises the architecture of the tree; c) he proposes Gompertz equations for the biomasses of the components of the tree and of the self-thinned even-aged pure stands; d) he presents simulator SB-CORSO. The simulator, for the same stands of Corsican pine establishes the yield table, the biomasses table and the table of the weights of N, P, K, Ca, Mg retained in the biomasses. In the second part of the paper, the author presents subprogram SB-CORSICANA. Knowing the structure of a self-thinned even-aged pure stand of Corsican pine, at a given age, for its symmetric uneven-aged stand, the program establishes (a) the stand structure (age and dbh classes, frequencies, standing volume, area per tree), and (b) nine alternative management guidelines.
