Advance subalpine fir regeneration has been assessed recently in five second-growth subalpine fir - Engelmann spruce stands resulting from early logging operations in the Kamloops Forest District. It was found that there is usually a delay of one full year after logging before diameter growth response.on the released advance regeneration and height growth may be delayed for several years.
Following this initial response delay period, advance subalpine fir regeneration is capable of excellent growth performance; Individual trees are affected by competition and site quality. No relationship was found between the age of advance regeneration and its growth response performance. The threat of decay to small size advance regeneration injured during the logging operation was found to be low. Also. the threat of heart-rot by the Indian paint fungus was low. but may increase with the age of the tree at the time of release.
Research Note No. 80 by L.J. Herring and titled "Studies of Advance Subalpine Fir in the Kamloops Forest District" describes details of this work. The results have been used as the basis for recommendations on silvicultural prescriptions aimed at utilizing advance regeneration as its partial stand restocking component. Post-logging treatment prescriptions aimed at maximizing growth and minimizing disease are presented.
