Pitch pines will survive fire, as long as it doesn't get too hot. I image because the area had intermittent openings and the forest service controlled the fire before it got out of hand. If the area wasn't open and the fire was just allowed to burn itself out, that would be another story.
I understand that many of the forest fires in the Pine Barrens are a result of arson. After reading Emile Divito's article, I wonder who these people are. Maybe someone who thinks he/she is doing the Lord's work by letting hot fires rip through the forest to create better biodiversity. It's something to think about. This, of course, is just a thought, an hypothesis.
