Soo TSA Young Stand Harvesting Soo TSA second growth harvest data HBS data indicates that about 36 % of the harvest was second growth in the past 5 years (2010 to 2014 in stands less than < 100 years of age). Results data suggests 35% of the harvest was harvested in second growth during the same period.
Soo TSA Young Stand Harvesting Soo Base Case (2011) and Second Growth Harvest Levels The initial harvest level of 480,000 m3/year can be maintained for 60 before incrementally increasing over the following 70 years to 580,000 m3/year. In the base case , stands were harvested oldest first above the minimum harvest ages (MHA) and a minimum harvest volumes (MHV). The model harvested: 11% from stands less than 100 years of age in the first 10 yr period of the harvest forecast, 24% in the second 10 year period, and 35% in the third 10 year period.
Soo TSA Young Stand Harvesting Base case Harvest Profile in Second Growth Stands The alignment between what is occurring on the land base operationally today and what was modelled in the base case is somewhat out of alignment (11% vs ~35% first decade). Likely the base case is somewhat overestimating timber supply as a result of not turning over the older stands that are not growing before moving into second growth.
