Which tree & stand characteristics determine beetle selection and
the resulting mosaic of mortality?
1. Summary of whitebark condition in the GYE
Whitebark & Non-Beetle Host
Whitebark & Alternate Beetle Host
(# preferred host attacked÷ total attacked)
(# preferred host available ÷ total available)
Sylvan Pass selection and
Selection Ratio 1.0 = No Preference
Step 2: Selection Ratio
*α = 0.05
1. whitebark over lodgepole
2. whitebark with heavy blister rust
Step 3: Multiple Logistic Regression selection and
Positive relationship between heavy rust & beetle selection.
