The pressures facing quaking aspen (Populus tremuloides) forests in the 
Intermountain West are multifaceted. Here we present Dr. Rick Lindroth 
(University of Wisconsin-Madison) to discuss the chemical defense 
mechanisms underlying aspen ecology and the roles that genotype, 
environment and their interaction play in impacting the effectiveness of 
defenses, and Dr. Sam St. Clair (Brigham Young University) will discuss 
the health of aspen forests within the ecological context of other 
environmental stressors facing this species in the Interior West. 

We hope you can join us for this interactive webinar presentation! ISA 
CEU's available.
