Regeneration delay


Regeneration delay is the period between harvesting and the time an area is occupied by a specified minimum number of acceptable well-spaced seedlings that are relatively free from growth-inhibiting brush, weed and excessive tree competition. In the Lillooet TSA, regeneration is accomplished primarily by planting. The timber supply analysis assumed a regeneration delay of 4 years. Current information from the Lillooet district office indicates the actual regeneration delays are 3.5 years in forest licence areas and 2.4 years in areas managed under the Small Business Forest Enterprise Program. Since forest licence areas dominate the TSA, the overall average is closer to 3.5 years, which is very close to that assumed in the base case. Therefore, I am satisfied the base case assumptions concerning regeneration delay are appropriate for this determination.
