Bark beetle damage spreading, Colorado foresters say
DENVER, Colorado ” State forestry officials say global warming is contributing to the spread of beetle forest damage across the state.
State Forester Jeff Jahnke told the state House and Senate agriculture committees Wednesday that an aerial survey last year shows another 500,000 acres of lodgepole and ponderosa pine were killed by the mountain pine beetle over the year before.
Jahnke said foresters also found a sharp increase in sudden aspen decline that affected another 542,000 acres last year.
Jahnke says climate change is making high elevation forests dry out more quickly, creating a risk of wildfires and increasing the chance of injury from falling trees.
