Lodgepole pine, a hardy tree species that can thrive in cold temperatures and plays a key role in many western ecosystems, is already shrinking in range as a result of climate change â€“ and may almost disappear from most of the Pacific Northwest by 2080, a new study concludes.
The caching of whitebark pine seeds by the Clark's nutcracker in late summer and early fall may not be enough to regenerate populations of the imperiled conifer in most of its range, scientists have found.
The genome of the fungus that helps mountain pine beetles infect and kill lodgepole pines has been decoded in a University of British Columbia study.
By studying similarities in the genes of Scots Pine trees, scientists have shown that the iconic pine forests of Highland Scotland still carry the traces of the ancestors that colonized Britain after the end of the last Ice Age, harboring genetic variation that could help regenerate future populations.

Montezuma pine (Pinus montezumae) is native to Mexico and Central America and grows in the mountain ranges. This tree is known as ocote by the locals of Mexico. This tree has been planted successfully at mid altitudes in South Africa and Queensland, Australia, and at high altitudes in Kenya, Malawi, Botswana, Zimbabwe, and Bolivia. Trees planted in New Zealand and New South Wales, Australia have done well at sea level. The Montezuma pine grows at 6,562-10,500 feet above sea level where...
Macedonian Pine (Pinus peuce) is native to Macedonia, Bulgaria, Albania, Montenegro, Kosovo, southwest Serbia, as well as the extreme north of Greece. This pine has been neutralized and grows in Eastern Finland. This pine grows best at altitudes between 3,281feet and 7,218 feet with a few growing as low as 1,969 feet and as high as 7,546 feet. This pine tolerates shade as well as extreme cold, and grows in rocky soils that are acidic and poor in nutrients. This tree grows to heights...
Limber Pine (Pinus flexilis) grows in the sub-alpine mountainous regions of the Western United States, Mexico, and Canada, with a small cropping found in the Black Hills in South Dakota. One of the oldest trees to be documented is found in Eagle Cap Wilderness in Oregon and is reported to be 2000 years old. This pine is also known as the Southwestern White Pine and Rocky Mountain White Pine. The Limber pine is drought tolerant and grows at high elevations (5000-12,000 feet) marking the...
