That is hilarious! The reviewer has never heard of a forest fire?! Or firewood? This is like our friends here who insist it is impossible to tell when half the water in a test tube boils away. (Okay, it might be 45% or 55% instead of half, but that would make no difference to the conclusion.)
I just assumed this particular reviewer was not familiar with biological processes at all. Albeit specialization is generally necessary, it can create a lot of blind spots, and this may be one example. I have usually been part of interdisciplinary research teams so you get a much more comprehensive understanding this way.
