A University of Alberta-led research team has determined that the mountain pine beetle has invaded jack pine forests in Alberta, opening up the possibility for an infestation that could stretch across the Prairies and keep moving east towards the Atlantic. A group of U of A tree biologists and geneticists discovered that, as the mountain pine beetle spread eastward from central British Columbia, it successfully jumped species from its main host, the lodgepole pine, to the jack pine. Jack pine...

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 "“ and may almost disappear from most of the Pacific Northwest by 2080, a new study concludes. Including Canada, where it is actually projected to increase in some places, lodgepole pine is expected to be able to survive in only 17 percent of its current range in the western parts of North America. The...

New study of Clark's nutcrackers suggests that their caching of whitebark pine seeds is less effective than previously thought at restoring populations of the declining conifer 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. Their research"”which is featured in the February issue of Science Findings, a monthly publication of the...

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. Also known as blue stain fungus for the stain it leaves in the wood of infected trees, Grosmannia clavigera is carried to the host trees by pine beetles and weakens the trees' natural defense system, allowing pine beetles to feed and reproduce in the tree bark. A successful beetle-fungus attack ultimately causes tree death. Now, researchers from...

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, according to new results published in the journal Heredity. The research was carried out by an international team from the Centre for Ecology & Hydrology, the Polish Academy of Sciences,...

If your summer travels have taken you across the Rocky Mountains, you've probably seen large swaths of reddish trees dotting otherwise green forests. While it may look like autumn has come early to the mountains, evergreen trees don't change color with the seasons. The red trees are dying, the result of attacks by mountain pine beetles. Mountain pine beetles are native to western forests, and they have evolved with the trees they infest, such as lodgepole pine and whitebark pine trees....

"My job was to locate the previously marked study trees. . .and record data on the activity of treated blister rust cankers," wrote Charles "Terry " Shaw. "The work took [me] in rickety four-wheel drive vehicles to remote locations scattered across the white pine forests of northern Idaho." Shaw, now editor of a recently published special issue of Forest Pathology, described how 44 years ago, he and other young forestry students collected data about a destructive forest disease for senior...

Long-lived pine pollen makes it difficult to contain transgenic trees When forest biologist Claire Williams boards ferries bound for North Carolina's Outer Banks, the barrier islands that line the NC coast, ferry captains call her the "Pollen Lady." Each spring from 2006 to 2009, Williams traveled back and forth from the islands to the mainland, collecting pine pollen blown far offshore. She wanted to find out if pollen from the loblolly pine "” the most commonly planted tree in the...

Forests in northern areas are stunted, verging on the edge of survival. It has been anticipated that climate change improves their growth conditions. A study published last week in Forest Ecology and Management journal shows that due to their genetic characteristics trees are unable to properly benefit from the lengthening growing season. Furthermore, the researchers were surprised to find that the mortality of established trees considerably promotes the adaptation of forests to the changing...
