Discussion
Pinus palustris is fire successional, with a deep taproot and a definite grass stage. It is a valued species for lumber and pulpwood and was once important for naval stores (e.g., turpentine, pine oil, tar, pitch). It is fast disappearing over much of its natural range, partly through overharvesting but especially because of difficulties in adapting it to current plantation and management techniques.
Longleaf pine (Pinus palustris) is the state tree of North Carolina.
