註釋
In 2000-01, aspen decline was observed over large areas of north-east Ontario. This study analyzes the bioclimatic characteristics of the areas affected and suggests potential causes of the decline. The bioclimatic characteristics analyzed include forest tent caterpillar defoliation; drought history; forest composition, age, & structure; and soil quality.
