Abstract
Did aspen decline go away?
John Guyon
Biologists have been discussing “aspen decline” since the 1970’s, but more recently events have led to increasing interest in the status of aspen forests. From around 2000 to 2010, almost 8 million acres of damaged aspen forest was documented from Canada to Mexico. Aerial surveys detected that the damage covered about 10% of the aspen host type in in the Intermountain West. Damage documented in aerial surveys has declined recently, but is still detectable. Episodic dieback and mortality appears to be part of the life history of aspen forests, but the scale of recent events seems unprecedented.
