Men shown harvesting resin from longleaf pine trees Pinus palustris close-up Mature longleaf pine tree with a prolific number of female cones. Lake City, Florida, 1929 Lake City, Florida, 1929 Vast forests of longleaf pine once were present along the southeastern Atlantic coast and Gulf Coast of North America , as part of the eastern savannas .
[3] [8] Longleaf pine resin was extracted for production of naval stores. To obtain the resin from the live longleaf pine, pioneers first cut and removed wood exposing a deep cavity, called a box at the base of the tree. Next a medium-sized, V-shaped cut was performed, above the box to start the resin flow into the box.
Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine (Pinus palustris), and slash pine (Pinus elliotii) in the tree canopy and saw palmetto (Serenoa repens), gallberry (Ilex glabra) and other flammable evergreen shrubs in the understory, along with a high diversity of herb species.
These are woodlands dominated by longleaf pine (Pinus palustris) and subject to frequent fires.The Atlantic coastal plain upland longleaf pine woodlands occur on uplands and on the higher parts of upland-wetland mosaics, while the east Gulf coastal plain interior upland longleaf pine woodlands occur on rolling dissected uplands, inland of the coastal flatlands.

Jeffrey pine wood and ponderosa pine wood are sold together as yellow pine. [6] Both kinds of wood are hard (with a Janka hardness of 550 lbf (2,400 N)), but the western yellow pine wood is less dense than southern yellow pine wood (28 lb/cu ft (0.45 g/cm 3 ) versus 35 lb/cu ft (0.56 g/cm 3 ) for shortleaf pine).
[15] [14] This practice of managing longleaf pine forests relies on a selective logging approach resulting in a diverse forest structure of uneven-aged trees. [16] Management of the understory is principally controlled by the use of prescribed fire and harvest selection takes into account many factors including sustained yield and aesthetics.
