That's a good question. Thank you.
Part of the difficulty is the scale. If it were small, isolated areas, I think we could do what you say. We could go in and do it, but look at just the province of Quebec, where the outbreak started in about 2005-06 in the north shore, north of Baie-Comeau, and got bigger and bigger, so that by 2017 it was in 7 million hectares. It's now 8.2 million hectares based on their surveys this year. Even with all of the salvaging that they can do, there's no road access in the north and it's just impossible to harvest there.
The Province of Quebec is spraying insecticides to try to keep trees alive. That's their approach. It's gone beyond where an early intervention approach would work. They're doing about 250,000 hectares or something of that order out of the 7 million or 8 million hectares that are there.
Salvage, harvesting and restructuring the forest are integral, along with some use of insecticides. The three can be merged together with an integrated long-term planning approach, so that you're using harvesting to reduce the vulnerability and using salvage in some places and insecticides in others. We've done that in other provinces.
