The species was imported in 1620 to England by Captain George Weymouth, who planted it for a timber crop, but had little success because of white pine blister rust disease. Old-growth pine in the Americas, of various Pinus species, was a highly desired wood since huge, knot-free boards were the rule rather than the exception. Pine was common ...
Slowdown in radial growth rates can occur without slowdown in corresponding cross-sectional area or volume growth. Leverett [ 26 ] compared growth rates of six young white pines ( Pinus strobus ), 75 to 90 years in age, growing along Broad Brook, MA with that of eleven old growth white pines from various other forest sites around Massachusetts.
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 ...
Dacrycarpus dacrydioides, commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp , it is New Zealand's tallest tree, gaining heights of 60 m over a life span of 600 years.
Millar et al. [21] observed increased growth in whitebark pine and accelerated encroachment into snowfields by whitebark pine and western white pine during the 20th century, particularly since 1980. Bunn et al. [22] showed that recent growth rates of subalpine conifers are greater than rates from any other period during the past 1000 years.
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.
Picea glauca (Moench) Voss., the white spruce, [4] is a species of spruce native to the northern temperate and boreal forests in Canada and United States, North America.. Picea glauca is native from central Alaska all through the east, across western and southern/central Canada to the Avalon Peninsula in Newfoundland, Quebec, Ontario and south to Montana, North Dakota, Minnesota, Wisconsin ...
The Swiss pine 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, with a deciduous sheath. The mature size is typically between 25 metres (82 ft) and 35 metres (115 ft) in height, and the trunk diameter can be up to 1.5 metres (4.9 ft).
