Its obvious this is a choice to let it burn. So, this may be a forest management choice to let the unburned area burn. Now that this is a National Monument, I wonder if the same kinds of fire management choices can or should apply. The issue is that pine trees don't come back after fires. Go to any of the last 15-years of burn scars and just try to find pine saplings. I don't spend a lot of time looking, but when I do they are few and far between. Many times I don't see any.
So, maybe it's time to think about protecting what we have, not managing it by letting it burn only to never come back.
