Description:
In this project, we have completed an initial calibration of the SORTIE-BC stand dynamics model for mixed stands in the Interior Cedar-Hemlock (ICH) zone of southern interior British Columbia. To do this, we have quantified, for an initial subsample, the growth response of juvenile trees (<10 cm diameter) growing under a range of light environments, characterized the probability of juvenile tree mortality, and investigated the effects of competition on the growth and survival of adult trees (>10cm diameter). In 2003 and 2004, we collected this information for paper birch, western redcedar, and western hemlock. We then used this data to calibrate SORTIE-BC for southern interior ICH mixtures, using northern interior data where southern interior data gaps still exist. With the re-calibrated model, we have done a preliminary examination of how complex stands respond to clearcutting and variable retention harvest. Results of the preliminary simulations will be used to guide field sampling for the next season.
