I have a stupid question about seasonal wildfires. I was under the impression that a lot of wildfires occurred because too much brush had built up and natural burns had been foolishly prevented by firefighters. However in the past 10 years, it seems that there are many, yearly, huge wildfires in the same areas.

Why doesn't the brush get burned down? ie, why is there not a Canadian wildfire every 5-10 years? Why yearly? Is it different locations? Does dry bush just accumulate that quickly? I'm aware that global warming is a factor, but if there's less to burn I'd think that warmer temperatures eventually hit a wall.

What do you mean by same area?

Canada has millions of sq km of forest. Lytton is 700km west of Jasper, which is 2000km west of Thunder Bay.
