Stand projection which is not corrected for stand-level increment and mortality tends to overestimate achievable yields in natural forest. Two recent models, SIRENA (a model driven by stand basal area dynamics from Costa Rica, and based only on a limited data set from a single remeasurement of permanent plots) and CAFOGROM.XLS (based on a much stronger set of basal area dynamics data from Brazil) are discussed. The stand basal area increment, mortality, and recruitment functions for SIRENA are illustrated, and various simulation trials with CAFOGROM.XLS shown. The author has extended the CAFOGROM.XLS modelling system by automating with a pre-processor program, CIMIR, for raw permanent plot data; this can be operated by non-programmers, but its application under current institutional arrangements in Ghana would be controversial, as each specific forest would need local management regimes to achieve optimal results.
