As if Colorado's trees didn't have enough insect problems with the notorious pine beetle, Boulder's forestry staff found emerald ash borers Monday, according to Denver's CBS affiliate.
As if Colorado's trees didn't have enough insect problems with the notorious pine beetle, Boulder's forestry staff found emerald ash borers Monday, according to Denver's CBS affiliate.
Since the emerald ash borer, a type of Asian beetle, was first detected in Michigan in 2002, the insects have killed more then 50 million ash trees in 21 states, but Colorado is the farthest west they have spread.
"The worse that can happen is we lose 1/5th of all our trees in the metro areas. So trees along the street, in our parks, neighborhoods, in our own backyards we can lose because of this insect," John Kaltenbach of the Colorado Department of Agriculture told CBS.
