Ips are usually not a problem in cooler weather (below 59 degrees F), but our warm, dry September and October this year has stressed trees and made ideal conditions for the rapid reproduction of Ips Bark Beetles.
To clean up this site and hopefully keep further attacks from happening, the landowner had recently killed trees removed from the site quickly. This practice will eliminate or slow the spread of this insect. Move harvested trees (tops and all) away from standing, healthy trees, especially in warm season harvests.
So, the case of the dying pines has been solved. Or has it?
While there is no doubt that the Ips beetle attack contributed to the loss of these trees. But were they really a symptom/result of something else? In our final installment, we will look at forest stand factors that could have also contributed to this event.
