Description: A severe windstorm in 1939 blew down extensive patches of Engelmann spruce (Picea engelmannii Parry) in western Colorado. A major epidemic of the Engelmann spruce beetle (Dendroctonus engelmanni Hopk.) developed from the windthrown trees and by 1952, when the epidemic was controlled by a combination of chemical and natural-control factors, an estimated four billion board-feet of Engelmann spruce and a half billion board-feet of lodgepole pine had been killed.

Keywords: Engelmann spruce, Picea engelmannii Parry, Engelmann spruce beetle, Dendroctonus engelmanni Hopk., western Colorado
