Subject: Forest Investment Account (FIA), PROGNOSIS (Computer Program), Dendroctonus Ponderosae, British Columbia
Series: Forest Investment Account (FIA) - Forest Science Program


The specific objectives of this project were to: (i) assess the predictions of PrognosisBC natural regeneration model against the Mountain Pine Beetle (MPB) data, (ii) study the effect of varying degrees of partial cutting on long-term model results, and; (iii) further develop and enhance the natural regeneration model software including any database design changes and updates. There are two separate reports in this document. The first report presents the research associated with objectives (i) and (ii) and is titled 'Implementing a PrognosisBC Regeneration Sub-model for Complex Stands of Southeastern and Central British Columbia: Use in MPB-Affected Stands and Results of Long-Term Projections in Partially Cut Stands'. The second report titled 'A Regeneration Model for PrognosisBC' provides details of the work associated with objective (iii). The natural regeneration model and data described in these reports constitute an integral part of the PrognosisBC growth and yield simulator and will be made available through the growth and yield website of the Ministry of Forests. Research results will also be made available through the PrognosisBC website at the University of British Columbia.
