Pinus contorta
Pinus contorta subsp. contorta, Coos Bay, Oregon <tr><th bgcolor=lightgreen>Scientific classification <tr><td>
Douglas </table> Lodgepole Pine (Pinus contorta) is a common tree in western North America. Like all pines, it is evergreen. There are three subspecies, one of them with two varieties:
- Pinus contorta subsp. contorta (Shore Pine) - Pacific Coast, southern Alaska to California
- Pinus contorta subsp. contorta var. contorta (Shore Pine) - Pacific Coast, Alaska to northwest California
- Pinus contorta subsp. contorta var. bolanderi (Mendocino Shore Pine) - Mendocino, California Coast
- Pinus contorta subsp. murrayana (Tamarack Pine or Sierra Lodgepole Pine) - Cascades Mountains, Sierra Nevada and adjacent mountain ranges, Washington south to northern Baja California
- Pinus contorta subsp. latifolia (Lodgepole Pine) - Rocky Mountains, Yukon to Colorado
Lodgepole Pines (subsp. latifolia) in Montana
This tree can be 30-40 m tall, but is often much smaller, particularly subsp. contorta, while subsp. murrayana can be larger, to 50 m. The needles are paired and often twisted, and 3-7 cm long. The 3-7 cm cones often need exposure to high temperatures (such as from forest fires) in order to open and release their seeds, though in subsp. murrayana they open as soon as they are mature. The cones have prickles on the scales.

It is occasionally known under several English names: Black Pine, Scrub Pine, and Coast Pine. The species name contorta arises from the twisted, bent pines found in the coastal area.
