Introduction—ecosystems, humans, and bark beetles. Large bark beetle outbreaks are regarded as major forest disturbances. In the United States, Dale et al. ranked them first, before hurricanes, tornadoes, and fire, with a 20,, ha average annual impact area and annual average costs (shared with pathogens) above US$2 billion per year. In Europe, over the Cited by:
