Lodgepole pine's fire-adapted lifestyle, which amounts to replacing itself as a result of periodic fires, has long been well known. That fire opens the cones of lodgepole pines by heating the resin that holds the cones together, spilling the seeds- a condition known as serotiny, is well known. Fire scientists have found evidence of fires from past centuries or even millenniums by studying tree rings and charcoal deposits. Forests of lodgepole pines (Pinus contorta Dougl) cover up to 50 million acres in the western regions of North America. Lodgepole Pine Tree Facts. Four varieties of lodgepole pine have evolved to adapt to this wide range of ecological conditions. Coutts MP (1982) The tolerance of tree roots to waterlogging: V. growth of woody roots of sitka spruce and lodgepole pine in waterlogged soil. All of these species require full sunlight to thrive, and all are well adapted to landscapes where fires regularly recur. Fire Ecology Pine trees have a number of fire related adaptations and this native plant can survive low intensity fires. Except for a few isolated cases in which it apparently forms climax stands, lodge-pole pine in the Rocky Mountains is a ser-al species maintained by fire. Notes: The lodgepole pine is a fire adapted species. It's cones are sealed with a hard wax that will usually only open when the temperature reaches 45C (120F). After a fire, forest regeneration on burned sites begins with the establishment of pioneer species, notably aspen, white birch, jack pine and lodgepole pine. More recently, ecologists have brought to light other species' relationships with fire. Factors affecting ..... occurrence, frequency, and intensity: ... lodgepole pine = Young forests are resistant to burning, due to ..... fuel availability, but older ones may be completely killed. Cones of northern populations of the interior variety latifolia are highly serotinous and retain vigorous seed for more than 50 years. cone type of Rocky Mountain lodgepole pine (Pinus contorta var. many species of ..... have adaptations for surviving fire, and some plant communities are highly dependent on fire for their continued existence. Three grow in California. Lodgepole pine, Pinus contorta Dougl. Crown fire is more typical in lodgepole pine forests, and the trees do not survive, as the bark is very thin. fire. latifolia) is maintained by temporal variation in the fitness of each type. Since it doesn't get that warm throughout the lodgepole pine's range, the cones will only open with the help of a forest fire. In most areas, this fire adaptation is mediated by New Phytologist 90, 467-476.

Douglas fir, lodgepole pine, and aspen in the central mountains in Colorado. The cone from a lodgepole pine opened by the Maple Fire: these trees require fire in order to disperse their seeds. Average annual cone production is relatively small, but the species is precocious; dominant trees accumulate large quantities of viable seed at an is the most widely distributed conifer in North America.

In addition to the thick bark and serotinous cones, Lodgepole pines also have the ability to move large quantities of water to the crown from the roots. Dense young lodgepole pine stands were converted to sparse stands by short-interval fire, whereas sparse stands regenerated as sparse stands. Lodgepole pine is a species which grows throughout the west, as far north as the Yukon and south to Baja California. The main factors addressed in fire ecology are fire dependence and adaptation of plants and animals, fire history, fire regime and fire effects on ecosystems. 3 Comments . It ranges east to the Black Hills of South Dakota and west all the way to the Pacific Ocean. Lodgepole pine is highly frost tolerant and can survive down to -70°F.
