![]() The sugar pine occurs in the mountains of Oregon and California in the Western United States, and Baja California in northwestern Mexico specifically the Cascade Range, Sierra Nevada, Coast Ranges, and Sierra San Pedro Martir. Sugar pine never grows in pure stands, always in a mixed forest and is shade tolerant in youth. The seeds are 1–2 cm ( 1⁄ 2– 3⁄ 4 in) long, with a 2–3-centimeter ( 3⁄ 4– 1 + 1⁄ 4-inch) long wing that aids their dispersal by wind. Sugar pine is notable for having the longest cones of any conifer, mostly 10–50 cm (4– 19 + 3⁄ 4 in) long, exceptionally to 60 cm ( 23 + 1⁄ 2 in) long (although the cones of the Coulter pine are more massive) their unripe weight of 1–2 kilograms (2.2–4.4 lb) makes them perilous projectiles when chewed off by squirrels. Like all members of the white pine group ( Pinus subgenus Strobus), the leaves ("needles") grow in fascicles ("bundles") of five, with a deciduous sheath. The upper branches can reach out over 8 m (26 ft). The bark of Pinus lambertiana ranges from brown to purple in color and is 5–10 centimeters (2–4 in) thick. Old sugar pines in the Rogue River – Siskiyou National Forest, southern Oregon Yosemite National Park also has the third tallest, measured to 80.5 m (264 ft 1 in) tall as of June 2013 the Rim Fire affected this specimen, but it survived. The tallest known living specimens today grow in southern Oregon and Yosemite National Park: one in Umpqua National Forest is 77.7 m (254 ft 11 in) tall and another in Siskiyou National Forest is 77.2 m (253 ft 3 in) tall. The second tallest recorded was "Yosemite Giant", an 82.05 m (269 ft 2 in) tall specimen in Yosemite National Park, which died from a bark beetle attack in 2007. The tallest recorded specimen is 83.45 m (273 ft 9 in) tall, is located in Yosemite National Park, and was discovered in 2015. The sugar pine is the tallest and largest Pinus species, commonly growing to 40–60 meters (130–195 ft) tall, exceptionally to 82 m (269 ft) tall, with a trunk diameter of 1.2–2.5 m (3 ft 11 in – 8 ft 2 in), exceptionally 3.5 m (11 ft 6 in). It is native to coastal and inland mountain areas along the Pacific coast of North America, as far north as Oregon and as far south as Baja California in Mexico. The species name lambertiana was given by the Scottish botanist David Douglas, who named the tree in honour of the English botanist, Aylmer Bourke Lambert. Pinus lambertiana (commonly known as the sugar pine or sugar cone pine) is the tallest and most massive pine tree, and has the longest cones of any conifer.
