Crews will cut trees on more than 200 acres around Vail this summer in their continuing efforts to battle the pine beetle epidemic.
This summer’s work will continue to create a ribbon of “defensible space” around the town that seeks to prevent the spread of fire...
“It’s to protect lives, homes and property from the effects of catastrophic wildfire,” ...
The work is part of the Vail Valley Forest Health Project, a multi-year effort coordinated by the Forest Service that seeks to combat the pine beetle infestation from East Vail to Edwards.
The mountain pine beetle epidemic has killed up to 90 percent of mature lodgepole pine in some areas near Vail.
“It’s just a cleanup of the fuel for fire,” ... “It’s very good to do it.”

I logged for a lot of years in the Sangre de Cristos. I never did see purple stain, but I saw a lot of blue stain which was caused by improper handling of the logs after cutting. IIRC, it is a fungus which grows in the wet wood because of heat and high moisture content when the logs are not debarked soon after cutting. The bark holds in the moisture and contributes to heat rise in the log promoting the blue-stain. That will also happen to trees on a south slope which are beetle killed and become standing dead with the bark on and exposed to the sunlight. The log temperature raises and the hot wet interior develops blue-stain.
The forests of the greater West/Southwest have had less than adequate rainfall for several years. This has weakened the trees and made them attractive to the insects. When a plant is weakened because of drought or other environmental factors, the plant attempts to heal itself by manufacturing higher levels of sugars in the sap which attracts insects. When the cycle runs its course and the rainfalls come up and the winter temps go down, then the insects will go away. Fire could play a good part in correcting that, as it will do in many area. However, the fire attracts other insects, so it is a never ceasing circle.
Wouldn’t DDT dusted from airplanes put a dent in it?
DDT is illegal plus the bugs have moved on to live trees elsewhere.
These trees are already dead and a spark away from a fire storm that could kill people, wipe out lots of homes and businesses.
Prevention could have been effective ten years ago but the Sierra Club lawyers prevented that.
