Q from unknown -

Is the blue spruce on my property at risk for bark beetle infestation? I go every year to chop down beetle killed trees in the Uintas, (pond pine, white fir), I bring it home, and use it for firewood. I have a blue spruce that I'm concerned may become infected.

Answer from Dr. Darren McAvoy, USU Extension Forester and Professor (sent 3/7/17) -

You are only putting your spruce at risk if you bring spruce logs down to your property; beetles are species specific. Bringing ponderosa and white fir will not threaten the spruce. Hope this helps.
