Excerpts from Jim Conrad's
from Jim Conrad's Naturalist Newsletter of May 22, 2005,
issued from California's Sierra Nevada Foothills:
We're at about 2600 feet here and the forest is dominated by Ponderosa Pines. Between here and the mailbox the road I jog on each morning dips into a valley where Digger Pines begin appearing. Digger Pines dominate the lower, drier elevations. By the same token, on our coral-root hike we were a couple hundred feet higher in elevation and in rainier territory, and there Sugar pines were about as numerous as Ponderosas. Here we say we're "going down into the Digger Pines," and "going up into the Sugar Pines." Let me tell you about those Sugar Pines, PINUS LAMBERTIANA, two of which are shown below:
Sugar Pines are famous for being the tallest US pine (up to 200 feet tall) and for producing the longest cones of any American conifer (up to 26 inches long). Below, a couple of long cones are being held by Diane.
Sugar Pines are members of "the White Pine group," and therefore on the stems the needles cluster in bundles of five. The authors of "Sierra Nevada Natural History," Tracy Storer and Robert Usinger, say very prettily of the Sugar Pine, "A big mature Sugar Pine on a mountain crest, with long cones hanging at the ends of its spreading branches, conveys the feeling of a beneficent patron." Well, here I'm slope-bound with no mountain crests at hand, but I can just imagine what they're talking about, and someday when it warms I'm hiking upslope until I see such a patron-pine.
Of course I'm always comparing our pines here with the Loblollies back in Mississippi. Both Ponderosas and Sugars produce trunks that to my Southeastern- biased mind seem much too large for the amount of green branches the trees bear. It would seem those Loblollies, having so much heat and rich soil, would produce the largest trunks. I suspect that what's happening is that the trees here grow much slower. They have larger trunks, but they take longer to produce trunks of a given size than fast-growing Loblollies.
The "sugar" part of Sugar Pine's name derives from the fact that fire and physical wounds cause a kind of resin to seep out that hardens into white nodules. If you're hard up for chewing gum, this can be chewed, and it is actually slightly sweet.

THE SUGAR PINE'S LONG CONES
This week suddenly I've started noticing remarkably long, slender cones dangling from the tips of certain especially tall, slender pines, as shown below:
Those cones are on a Sugar Pine, PINUS LAMBERTIANA, found naturally only from Oregon through California into Mexico's northern Baja. Sugar Pines, reaching 200 feet tall (61 m), are the tallest of all American pines; their cones, up to 26 inches long (66 cm), are the longest cones of any American conifer.
Sugar Pines belong to the Soft Pine group, most species of which bear five needles per cluster, or bundle. The other pines I've introduced you to from here -- the Ponderosa, Jeffrey and Knobcone -- all are Hard Pines with three needles per bundle, except some Ponderosa bundles have only two.
