The Forest Vegetation Simulator (FVS) predicts forest growth for 19 geographic locations in the United States and Canada. However, only four of the 19 geographic variants have models that simulate the process of regeneration establishment. Considerable work needs to be done to develop regeneration models for all FVS variants. An alternative to designed research studies is to use stand examination inventory data to develop regeneration models. The most important data consideration is to locate and use unbiased inventories. Fortunately, many organizations already collect the data needed to develop such regeneration models. Ideas are presented for designing stand examinations that provide data for regeneration modeling.
