Lodgepole pine forests are an important landscape feature in the western parts of North America. They grow in shallow, rocky soils, and do no require much rainfall. except jack pine (Pinus banksiana), lodgepole pine (Pinus contorta), and balsam fir (Abies balsamea). Jack pine is a relatively small, short-lived, early successional tree occurring in the eastern and central parts of taiga east of the Rocky Mountains. Lodgepole pine is a longer-lived, early successional species growing in western Canada. Title.

Oregon's only native two-needle pine, Pinus contorta, commonly called lodgepole pine, is widely distributed across the state in a variety of diverse ecological habitats, from windswept ocean shores to mountaintops. Pinus contorta is named for its gnarled, twisted shape in its seashore habitat or, perhaps, the gentle twist in its paired needles. Three named forms in Oregon have been treated as.

P. contorta is a 2-needled pine of the subgenus Pinus (distinguished by having much resin, close-grained wood, sheath of leaf cluster persistent and two vascular bundles in each needle), section Pinus, subsection Contortae, along with the North American species P. banksiana, P. virginiana and P. clausa (Little and Critchfield, ).

Lodgepole pine is commonly associated with meadows (Rundel et al. ). Although lodgepole pine has well developed water regulation mechanisms, it typically occupies areas with at least seasonally wet soils. Annual precipitation in the lodgepole pine zone averages from to mm (30 to 40 in) annually, mostly as snow.
