Pinus albicaulis is the only type of tree on the summit of Pywiack Dome in Yosemite National Park. Pinus albicaulis, known by the common names whitebark pine, white bark pine, white pine, pitch pine, scrub pine, and creeping pine, [4] is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific ...
Diameters of the larger pines range from 1.0–1.6 m (3 ft 3 in – 5 ft 3 in), which translates to a circumference (girth) range of 3.1–5.0 m (10 ft 2 in – 16 ft 5 in). However, single-trunked white pines in both the Northeast and Southeast with diameters over 1.45 m (4 ft 9 in) are exceedingly rare.
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 ft) tall. It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, [5] with a deciduous sheath. The needles are finely serrated, [5] and 5
The female (seed) cones mature in about 20 months from pollination; when mature, they are yellow-brown in color, 15–25 cm (6– 9 + 3 ⁄ 4 in) long, and 5–7 cm (2– 2 + 3 ⁄ 4 in) broad, opening to 12 cm (4 + 3 ⁄ 4 in), and have a small, but sharp, downward-pointing spine on the middle of each scale.
Limber pine (Pinus flexilis), another of these species from western North America, was also sometimes known as White Pine; Chinese white pine (Pinus armandii), a species native to China; Japanese white pine (Pinus parviflora), a species native to Japan; Vietnamese white pine (Pinus dalatensis), a species native to Vietnam and Laos
These birds are known to cache 32,000 pine seeds and transport the seeds as far as 12–22 km (7.5–13.7 mi) from the source. The birds store the seeds in the soil at depths of 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) under conditions which favor germination .
The seed cones open to 6–9 cm (2 + 1 ⁄ 4 – 3 + 1 ⁄ 2 in) broad when mature, holding the seeds on the scales after opening. The seeds are 11–16 mm ( 7 ⁄ 16 – 5 ⁄ 8 in) long, with a thin shell, a white endosperm , and a vestigial 1–2 mm ( 1 ⁄ 32 – 3 ⁄ 32 in) wing.
Pinus elliottii, commonly known as slash pine, [2] [3] is a conifer tree native to the Southeastern United States. Slash pine is named after the "slashes" – swampy ground overgrown with trees and bushes – that constitute its habitat. Other common names include swamp pine, yellow slash pine, and southern Florida pine. [3]
