The Jeffreypine beetle (Dendroctonus jeffreyi Hopk.), one of the bark beetles that kill trees by mining between the bark and the wood, is the principal insect enemy of Jeffreypine.
The Jeffreypine beetle is a native insect.
In diagnosing Jeffreypine beetle as the cause of damage, it is important to establish the infested tree is Jeffreypine.
Jeffreypine was first classified as a variety of ponderosa pine, and has identical wood properties of ponderosa pine.
Distribution: Jeffreypine is native to the mountains of southwestern Oregon south in California through the Sierra Nevada to western Nevada and to southern California.
Uses: Jeffreypine (ponderosa pine) is used mainly for lumber and to a lesser extent for piles, poles, posts, mine timbers, veneer, and railroad crossties.
Jeffreypine was discovered in 1852 in the Shasta Valley of California by Scottish botanist, John Jeffrey.
Jeffreypine typically grows on granitic and volcanic soils in the Sierra Nevada, with coarse soil texture, as gravelly sandy loams or loamy coarse sands.
Jeffreypine pitch was distilled for turpentine early in the century.
SDNHM - Pinus jeffreyi (Jeffrey Pine, Yellow Pine)(Site not responding. Last check: 2007-10-08)
A large symmetrically shaped pinetree growing to 20-50 m (60 to 150 feet) high with blue-green needles 12 to 28 cm (5 to 11 inches) long, occurring in sets of threes.
JeffreyPine is present in Baja California in the Sierra San Pedro Mártir and Sierra Juárez, through California, and north to Oregon.
This is one of the most common pines in the mountains of Baja California.
Pines can grow in alkaline soils, and even poor -draining soils, but they usually do not live long, except in their range.
In lower rainfall areas, such as southern California, the pines can compensate somewhat in older stands with fog drip, but if a large -area fire, weed invasion or clearcut occurs, the trees cannot regenerate on their own, because there is just not enough rainfall.
The original Jepson manual had JeffreyPine as a variety of Ponderosa and it is often very hard to tell the two apart in the field.
Similar Species: JeffreyPine is most likely be confused with Ponderosa Pine within its range and, in fact, was earlier considered to be a variety of Ponderosa Pine.
Although the morphology of the bark of the two species is similar, the bark of JeffreyPine is a distinctive reddish-brown.
In contrast the bark of Ponderosa Pine is yellowish-brown or fl.
The King of the Pines, called the "Queen of the Sierras" by John Muir, Pinus lambertiana, Douglas, the famous Sugar Pine from California, is the world's largest species of pine reaching heights of 200 feet and more than 60 inches dbh (diameter at breast height).
The Jeffreypine was discovered in 1852 in the Shasta Valley of northern California by John Jeffrey, a Scottish botanical explorer.
Partly overlapping ponderosa pine in range and superficially resembling it, Jeffreypine was first classified as a variety of ponderosa pine.
Yosemite's famous Jeffreypine on Sentinel Dome -- whose poetic beauty and unique, wind-swept formation made it one of the most photographed trees in the park, if not the world -- has crashed down.
Part of the appeal of the Jeffreypine, many say, was its improbable location.
Park rangers say the tree, which was up to 400 years old and stood nearly 12 feet tall, probably grew there after an errant seed dropped by a bird managed to take root through a crack in the granite.
