Description:
Selection logging is of considerable importance throughout the dry-belt areas of British Columbia’s central and southern interior. However, lack of good long term data continues to be the major impediment to improved growth and yield estimates for residual stands. One of the few existing well-designed studies of the effects of different levels of growing stock and stand structure on growth and yield was established in 1993 in an uneven-aged stand of dry-belt Douglas-fir near Westwold in the Vernon Forest District. Ten years post-establishment, we re-measured the permanent plots, assessed the natural regeneration, and installed permanent regeneration subplots. There were no significant differences in seedling number, quality or height across the range of residual stocking levels in the experiment, according to analysis of variance (p=0.05). A first approximation of a regeneration dispersion module was developed for the TASS growth and yield model, establishing a prototype system that will be adapted to a broader range of priority sites and variable retention stand structures.
