Old growth longleaf pine stand, scorched by fire (top); longleaf pine stand after timber removal (bottom) Before European settlement, longleaf pine forest dominated as much as 90,000,000 acres (360,000 km 2) stretching from Virginia south to Florida and west to East Texas. Its range was defined by the frequent widespread fires that were lit by ...
Pinus jeffreyi occurs from southwest Oregon south through much of California (mainly on the eastern side of the Sierra Nevada), to northern Baja California in Mexico. It is a high-altitude species; in the north of its range, it grows widely at 1,500 to 2,100 m (4,900 to 6,900 ft) altitude, and at 1,800 to 2,900 m (5,900 to 9,500 ft) in the south of its range.
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).
Cones of all species have thick scales, and all except those of P. pinea open at maturity. Species in this section are native to Europe, Asia, and the Mediterranean, except for P. resinosa in northeastern North America and P. tropicalis in western Cuba.

Fire reduces competition with different tree species which increases shortleaf pine survival, and it also prepares the soil for regeneration. Shortleaf pine typically respond well to prescribed fire. [12] With frequent fire, the species can occur in savanna environments, with a very diverse understory and prime habitat for the red-cockaded ...
I do not remember ever thinking about pinecones being a crop, nor about a fluctuation in the number of pinecones from year to year.
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.
