Cover Story: Bark beetles are some of the most important drivers of change in forests throughout the Earth’s Northern Hemisphere. These native insects typically persist at low populations in conifer forests, yet irruptive outbreaks can also occur rapidly across large areas. Over the last 20 years, outbreaks of three bark beetle species (Dendroctonus rufipennis, Dendroctonus ponderosae, and Dryocoetes confusus), triggered by above-average drought conditions, have led to broad-scale forest mortality in the Southern Rocky Mountains, USA. Using Landsat time series with field validation, the effects of these outbreaks was quantified across this complex region. Over 10,000 km2 of subalpine forest area was affected by bark beetles; while effects of the outbreaks were severe in many places, they were highly variable across the region. View this paper
