lodgepole pine (Pinus contorta)
(click on each photo to enlarge image)
-
Needles: Two needles per bundle (clustered);
1-3" long; commonly twisted
(contorted).
-
Fruit: Small, egg-shaped cones (1-2" long),
often with a prickle at the end of each scale. May remain closed on
the tree for years.
-
Bark: Thin, dark, and flaky.
-
Distribution: Abundant in the northern Rocky Mountains and Pacific Coast
region. Grow from 0-11,500 ft. (0-3600 m). Those along the coast are commonly
called shore pine.
ponderosa pine (Pinus ponderosa)
(click on each photo to enlarge image)
-
Needles: Occur
in bundles of 3 (rarely 2); 5-10" long; tufted near the
ends of branches (needles are held only 2-3 years).
-
Fruit: Egg-shaped
cone; 3-5" long (much smaller than
Jeffrey pine cones); each scale has a straight, stiff prickle that sticks out.
-
Bark: Flakes
off in shapes like jigsaw puzzle pieces. Older trees have a distinct
yellow or orange color (not red like Jeffrey pine).
-
Distribution: Occurs in the Pacific
Coast mountain ranges, throughout the Rocky Mountains, and into northern
Mexico. Grows from sea level to 9000
ft. (2800 m).
Jeffrey pine (Pinus jeffreyi)
(click on each photo to enlarge image)
-
Needles: Occur
in bundles of 3 (rarely 2); 5-10" long; often "bushy" along twig (often
held 5-8 years on the tree).
-
Fruit: Large,
woody cones; 5-12" long (much larger than
ponderosa pine cones); each scale has a curved (J-shaped) prickle that
curves inward.
-
Bark: Flakes
off in jigsaw puzzle-like pieces. Older bark is distinctly reddish-brown
(not as orange as ponderosa pine).
-
Distribution: Occurs in mountainous
regions of the West, from southern Oregon through the Sierra Nevada,
and into Baja, California. Generally grows
from 4800 to 9600 ft. (1500-3000 m).
knobcone pine (Pinus attenuata)
(click on each photo to enlarge image)
-
Needles: Occur
in bundles of 3; 3-7" long;
slender and twisted.
-
Fruit: Woody
cones with swollen, knob-like bumps on one side; 3-6" long;
grow in dense clusters. Cones may remain closed on the tree for many years.
-
Bark: Dark and scaly.
-
Distribution: Found
on dry, rocky slopes and ridges of the coastal mountain ranges; southern
Oregon to Baja, California.
Usually grow at 2600-4500 ft.
(800-1350 m). Grows in fire-prone environments.
western white pine (Pinus monticola)

-
Needles: Occur
in bundles of 5; 2-4" long;
white lines on 2 sides of each 3-sided needle.
-
Fruit: Woody
cones, 5-12" long (smaller than
sugar pine cones); slender
and curved. Cone scales are thin and often curve up on
the end.
-
Bark: Dark; broken into small squares or
rectangles on older trees (smooth on young trees). Bark often "ringed" where
a whorl of branches once grew.
-
Distribution: Occurs in southern British
Columbia, the northwestern states, and the Sierra Nevada of California.
In the northern portion of their range,
the trees grow from sea level to 2500 ft. (750 m).
sugar pine (Pinus lambertiana)
(click on each photo to enlarge image)
-
Needles: Occur
in bundles of 5; 2-4" long;
white lines on all 3 surfaces of each 3-sided needle.
-
Fruit: Huge,
woody cones, 10-20" long
(larger than western white pine cones) and straight. Cone
scales are thick and straight.
-
Bark: Reddish-brown
and furrowed; broken into long plates on older
trees (narrow plates on young trees). No small blocky patches, and
no rings where whorls of branches once grew (each distinguishes
sugar from western white pine).
-
Distribution: Ranges from the mountains
of southern Oregon to southern California, the Sierra Nevada, and
into northern Baja, California. Occur from 2300 to
9200 ft. (750-3000 m).
limber pine (Pinus flexilis)
(click on each photo to enlarge image)
-
Size: Usually under 50' tall and 2' in
diameter. Often shrubby.
-
Needles: Occur
in bundles of 5; 2-3" long;
white lines on all surfaces.
-
Fruit: Woody
cones, 3-7" long; thick
cone scales with no prickles.
-
Bark: Grayish-brown with furrows and
ridges.
-
Distribution: Distributed widely in the
Rocky Mountains from Canada to northern New Mexico; found in northeast
corner of Oregon. Usually found
on
dry, rocky ridges and peaks at 7700 to 11,500 ft. (2350-3600 m) elevation.
whitebark pine (Pinus albicaulis)
(click on each photo to enlarge image)
-
Size: Usually under 50' tall and 2'
in diameter. Often distorted or shrub-like.
-
Needles: Occur
in bundles of 5; 1-3" long;
faint, white lines on all surfaces.
-
Fruit: Small,
woody cones, 2-3" long; nearly
round; thick cone scales with no prickles. Remain closed on tree even
when mature; Seeds are unwinged
and a rich source of food for animals.
-
Bark: Thin, scaly, and grayish throughout
its life.
-
Distribution: Found in the high mountains
of western Canada and the U.S. Grows at or near timberline from 7700
to 12,000 ft. (2350-3750 m) elevation.
