Pinus lambertiana, commonly known as sugar pine, is found on the West Coast in the mountains of Nevada, California, Oregon and Mexico. Sugar pine is the tallest of all pines and has the longest cones of any conifer. In these regions it is very important for both economic and environmental reasons. (Habeck) The sugar pine is said to be the largest pine in the world, reaching a height of nearly 200 feet with a trunk diameter of seven feet. (About the sugar pine) The tallest recorded sugar pine still alive today, however, is 255 feet tall with a diameter of seven and a half feet. It was found in the Rogue River-Siskiyou National Forest. These trees can reach an age of around 400-500 years. Sugar pines also have huge cones that average 12-18 inches long, but some can be up to a foot long. (About sugar pine) Their range begins from the western slope of the Cascade Range in north-central Oregon to the Sierra San Pedro Martir in Baja California. Most of its distribution is centered on the Klamath and Siskiyou Mountains and the western slopes of the Cascade Range and Sierra Nevada. Smaller patches are also found on the southern Oregon and California coast, on the Transverse Ranges of southern California, and east of the Cascade Ridges and Sierra Nevada. Nearly 80% of its distribution is in California. (Habeck) Sugar pines are found in a variety of locations, including moist, steep, north-, east- and south-facing slopes. They tend to like deep, well-drained soils with a light to neutral acidity level. While these trees can and do grow on steep, rugged terrain, the best growth occurs on gentle soils at medium elevations in sandy to loamy soils. These sugar pines grow from sea level to a maximum of about 10,000 feet. The ele...... half of the document ......lsFattig, P. (2012, June 04). Tree hunters find the world.
