You're right. Certainly, the management decisions and the management strategies that have led to the situation in B.C. in particular are not just fire suppression—and that's a big piece of the story—but certainly the fact that we do have these uniform age stands is really the key point there.
Just having a monoculture, which would just be everything being a single species, that is less of a concern if there is a mix of ages. Typically, when you have fire coming through these forests, it does help provide some of that variation in age, which adds to the resiliency of those forests to these sorts of outbreaks.
With respect to the second part of your question, in terms of what we can now do, now that we have clear-cut large areas and we're replanting, I believe we need to be ensuring that when we go to replant we're not just putting back another monoculture and that it's not going to end up being a uniform age class, because that would set us up in another 100 years to go through the exact same problem again.
We really do need to be mindful of trying to plant mixed species but also of trying to alter, potentially, our harvest regimes so that we aren't just clear-cutting large swathes and we are leaving some residuals in order to have a nice mixture of growth in the forests.
