Abstract: Extensive regeneration surveys on drag scarified areas in the Prince George S.S.A.'s and the Westlake and Nechako P.S.Y.U.'s showed that the stocking percent distribution* increases with time (up to 6 years) since scarification. Five years after drag scarification, a large percentage of the sites surveyed supported 4,000 - 10,000 stems per ha and therefore some thought should be given to regeneration control during the drag scarification process on those sites with an overabundant seed source. This may be accomplished by limiting site disturbance during treatment, or delaying treatment up to one season after logging. Research Note No. 84 by L.M. Glen and G. Ackerman entitled "Proposed Amendments to the Regeneration Survey System used on Drag Scarified Sites in the Prince George Forest District" describes details of this work, including tables and a graph which show the increase in percentage stocking distribution with time. The incorporation of all relevant drag scarification information in a standard format, methods of controlling regeneration on sites with an overabundant seed source and a five year delay before regeneration surveys are recommended. For more information write to the Information Division, B.C. Forest Service, Legislative Buildings, Victoria, B.C. V8V 1X5 * The percentage of the total number of plots that contain at least one acceptable seedling. [Abstract contains full text of memo.]
