Yes, sometimes a natural burn can be utilized as a lucky backfire that firefighters don't have to light, or as a natural firebreak, having burnt off the available fuel. LOL-ing (at hubby) I just asked him if he knew what those rare occurrances were called in the jargon...he just said "LUCKY, becaue they don't happen often."
He's right, they don't. They probably DO have a special terminology in Timber Management jargon...but I can tell you that the terminology IS most likely different than that of the actual firefighters...and probably more printable.
Yah, I can imagine...
