Pinus rigida, the pitch pine, [2] [3] is a small-to-medium-sized pine. It is native to eastern North America , primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils.
The commercial use of fatwood from stumps stemmed from the production of pitch and pine tar. In 1648, a company was formed in Sweden called Norrländska Tjärkompaniet (The Wood Tar Company of North Sweden), and was given exclusive export rights for pine tar by the King of Sweden. [2]
Pitch was a base ingredient in many incendiary devices throughout the period. The Boeotians developed a fire machine, which they used against the Athenian wooden fortifications during the Battle of Delium in 424 BC. A cauldron of burning coals, pitch and sulfur was suspended at one end of a hollowed-out log and bellows were fixed to the other ...
Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar , or from plants, as in pine tar .
Their serotinous pine cones open only after having been heated by a fire. [7] [33] The prevalence of forest fire allows the pitch pines to dominate over oaks, which by comparison are usually killed outright by a moderate or intense fire. High air temperatures and dry plant undergrowth contribute to the intensity of the fire.
Shortleaf pine seedlings develop a persistent J-shaped crook near the ground surface. [4] Axillary and other buds form near the crook and initiate growth if the upper stem is killed by fire or is severed. [5] The bark has resin pockets (sometimes called pitch patches), which form small depressions, less than 1 millimetre (1 ⁄ 32 in) in
A toddler was hit and killed by a vehicle in the 7500 block of Pitch Pine Circle in Tampa Thursday evening, according to the Hillsborough County Sheriff's Office.
The Hominy Hills fall within the Pinelands region, and exhibit both pine dominated and oak dominated forests, as well as intermediate forests. Pitch pine ( Pinus rigida ) is the most abundant tree. A variety of oaks are also present, including black ( Quercus velutina ), white ( Quercus alba ), post ( Quercus stellata ), chestnut ( Quercus ...
