Abstract:Yearly trends of a mountain pine beetle (Dendroctonus ponderosae Hopk.) infestation were measured in a 640-acre lodgepole pine (Pinus contorta Dougl.) tract in Yellowstone National Park. Before infestation the tract had 211 live trees per acre 5 inches d.b.h. and larger. A seven-year outbreak killed 56 trees per acre, the peak mortality of 27 trees per acre occurring in the fourth year.
