“to the extent possible, the [harvest] is completely dedicated to removing, as a first priority, timber that has already been affected” by MPB.
Pedersen, L. 2004.
“it is essential to ensure in the wake of this epidemic that non-pine stands are reserved for future timber supply.”
Benskin, H. 2005.

Conclusions
All of the increased AAC has been devoted to harvesting pine.
Non-pine trees are harvested because:Not all wood products can be made from pine.
Pine often occurs in mixed stand and we clearcut.
If we continue with the current harvest profile:At least 1.5 million ha of dead pine will not be harvested.
Up to 80% of the “mixed stands” will be harvested.

Concerns –
about monitoring harvest
The cutting permit is the finest level of spatial resolution in the Harvest Billing System.

Concerns –
about monitoring harvestThe Harvest Billing System records volumes brought to mills – there is no record of much of the volume that is harvested but left on site.

Summary
The harvest profile is meeting MoFRexpectations.Non-pine trees are harvested because of:
Economic imperatives.Physical constraints.
The current harvest profile may have negative consequences in the future.There are concerns about our ability to monitor harvesting.
