I can start, and maybe Jean-Luc can pick it up.
Yes, absolutely. The normal cycle for the mountain pine beetle is eight to 10 years. It certainly lasted longer in B.C. and the last outbreak was definitely more severe. The traditional method is to cut, pile, burn, and get rid of the single trees, and amend the harvesting regimes to focus on beetle-infected wood, if you can. But at this point there really aren't a lot of new types of control methods that we can use. TreeAzin has been applied, but that's hundreds of dollars per tree. It's not practical in the forest. It might be in higher-valued types of trees.
Jean-Luc, do you want to comment?
