PrognosisBC is a growth and yield model developed to predict the impacts of partial cutting on future stand structures in multi-species and/or multi-age stands. Applications of the existing version of this model are limited by the lack of a natural regeneration component. The research and extension activities outlined in this proposal are aimed at continuing the implementation of a natural regeneration model within the context of PrognosisBC . This work is based on the regeneration imputation techniques developed at the Department of Forest Resources Management, UBC, for a number of important biogeoclimatic ecosystem classification subzone variants in southeastern and central British Columbia. The model's prototype, which was developed through FII funding in 2002/2003, will be further tested and validated in the second year. The new model will provide the tool needed to project the dynamics of complex stands under partial harvesting regimes.
