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 ...
[6]: 11–12 Vast acres of the longleaf pine in the southeast were cleared to aid in ship building for the war effort. With this push in demand, 1909 marked the peak of longleaf pine lumber production. At this period, it was realized that decline in the ecosystem was eminent through the bare landscape with little regeneration of longleaf pine.
Historically, the flatwoods were dominated by longleaf pine, which can live to be 500 years old. Large scale overharvesting in conjunction with detrimental silvicultural practices like replacement with faster growing loblolly pine has drastically reduced the range of the longleaf pine ecosystem. Longleaf requires frequent fires, ideally every 1 ...

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.
The Palustris Experimental Forest was established July 19, 1935 [1] on 2,700 acres (1,100 ha) of cutover land that was previously occupied by longleaf pine. [6] The experimental forest was to serve as a field laboratory for evaluating pine reforestation techniques.
An example of a naturally occurring hybrid pine is Pinus × sondereggeri, a naturally occurring cross between loblolly pine (P. taeda) and longleaf pine (P. palustris). An example of the many artificial hybrids is Pinus lambertiana × P. armandii. [1]
A pine is any conifer tree or shrub in the genus Pinus (/ ˈ p aɪ n ə s /) [2] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.. World Flora Online accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, [3] and Plants of the World Online 126 species-rank taxa (113 species and 13 nothospecies), [4] making it ...
