Presentation Transcript

  1. PNW Pines (Pinus)

  2. Pines • About 115 species • Native to most of the Northern Hemisphere • Evergreen, coniferous • Mostly trees, rarely bushes • 3-80m tall • Tallest is a Ponderosa Pine located in Southern Oregon

  3. Pine Ecology • Grow well in acidic soils. • Well drained Sandy Soils • Can tolerate extreme conditions due to elevation and latitude • Bishop Pines need fire to regenerate

  4. Uses • Used largely as timber • Furniture, homes • Resin is used for turpentine • Used as ornamental plants • Used for pine nuts

  5. Lodgepole Pine • 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.

  6. Ponderosa Pine • Needles: bundles of 3, 5-10 inches long; held for only 2-3 years. • Fruit: Egg-shaped cone; 3-5 inches 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).

  7. Jeffery Pine • Needles: bundles of 3, 5-10 inches long; often "bushy" along twig. Last 5-8 years on tree. • Fruit: Large, woody cones; 5-12 inches 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)

  8. Western White Pine • Needles: Occur in bundles of 5; 2-4 inches long; white lines on 2 sides of each 3-sided needle. • Fruit: Woody cones, 5-12 inches long.  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

  9. White-bark Pine • Needles: Occur in bundles of 5; 1-3 inches long; faint, white lines on all surfaces. • Fruit: Small, woody cones, 2-3 inches long; nearly round; thick cone scales with no prickles. • Bark: Thin, scaly, and grayish throughout its life
