Scientists report success in treating seedlings with mushroom spores
FRISCO — High-elevation whitebark pines are under the gun in the northern Rockies. White pine blister rust, an invasive fungus, and pine beetles have combined to drive the species toward extinction.
But scientists trying to recover the species say that a humble mushroom could help their efforts. A three-year experiment shows a 10 to 15 percent increase in the survival rate of whitebark pine seedlings when Siberian slippery jack spores are injected into the soil around them. The injection takes place in nurseries before the seedlings are transplanted in the mountains. Continue reading

Researchers see threat to whitebark pines
By Summit Voice
FRISCO —Bark beetles have already killed millions of acres of mid-elevation forests across the West, and warming temperatures are enabling the tree-killing bugs to invade higher elevations, where they are attacking trees that haven’t evolved with strong defenses to repel them.
Global warming is essentially giving the insects a huge advantage, as the trees, with their long lifespans, have no chance to develop biological resistance, according to researchers from the the University of Wisconsin-Madison, who report a rising threat to the whitebark pine forests of the northern Rocky Mountains.
