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, this project will re-measure the permanent plots, assess the natural regeneration, and complete the installation of permanent regeneration sub-plots to provide best available information on uneven-aged stand growth and regeneration. A natural regeneration module will be developed for the TASS growth and yield model, establishing a prototype system that we will adapt to a broader range of priority sites and variable retention stand structures in future years.
