Actually, most of those pine forests were planted by St. Joe, on a lot of low lying wet land. Those pines grow everywhere, wherever they find any wet organic matter. I've seen seedlings on roofs, windshield crevices, cracks in decks, etc. Imagine South Walton without all those pines and that's what it used to look like. The original long leaf pine was used for Turpentine, and had a lot of sap. Fat lighter, impervious to insects, but highly flammable. I am very skeptical on the notion that a burn is necessary. Dad had a tree farm from the 40?s or 50?s, and he saw no need for a control burn.
