* TREES: sugar pine forest ecosystems, including a mix of conifers like Jeffrey pine
, ponderosa pine, western white pine, Douglas-fir and incense cedar
California (High Sierra Ranger District, Sierra National Forest): The project will span 600 acres and will plant 128,500 seedlings, a mix of ponderosa pine, Jeffrey pine
, sugar pine, white fir and red fir.
Tahoe Conservancy and League staff carry Jeffrey pine
and incense cedar seedlings for planting about 30 acres in the Angora burn area.
Black bears (Ursus americanus) harvest Jeffrey pine
(Pinus jeffreyi) seeds from tree canopies.
The truth is, thinning can't even reduce the risk of severe fire, as demonstrated by ecologist George Wuerthner's observations of 2002's Biscuit fire: "Many of the low-density, widely spaced Jeffrey pine
growing on serpentine burned up even though their natural stand density is much lower than what you are left with under even aggressive thinning." When drought, high temperatures, low humidity and wind combine - which we're seeing more of with climate change - a fire's going to burn, no matter how many stumps are in its way.

* Forest Giants of the Pacific Coast, by Robert Van Pelt (Global Forest Society/University of Washington Press, $35), leads off with the giant sequoia and the coastal redwood, but then concisely describes and discusses 18 other western giants, among them the Jeffrey pine
, western hemlock, and yellow cedar.
The three species of pines used occur sympatrically and produce similarly-shaped, winged seeds that differ in size: lodgepole pine (Pinus contorta; 9 [+ or -] 2 mg, filled seed including wing), ponderosa pine (Pinus ponderosa; 62 [+ or -] 11 mg), and Jeffrey pine
(Pinus jeffreyi; 185 [+ or -] 23 mg).
Western long-needled pine forests, especially ponderosa and Jeffrey pine
ecosystems, have declined in diversity and productivity over the past 150 years.
, too, reaches its northern range limit in the Klamath.
Tenders are invited for Sale of timber estimated volume of 20 CCF of lodgepole pine fuelwood, 145 CCF of fir fuelwood, and 23 CCF of Jeffrey pine
fuelwood marked or otherwise designated for cutting.
