Ponderosa pine mortality resulting from a mountain pine beetle outbreak
1982
McCambridge, William F. | Hawksworth, Frank G. | Edminster, Carleton B. | Laut, John G.
"From 1965 to 1978, mountain pine beetles killed 25% of the pines taller than 4.5 feet in a study area in north-central Colorado. Average basal area was reduced from 92 to 58 square feet per acre. Mortality increased with tree diameter up to about 9 inches d.b.h. Larger trees appeared to be killed at random. Mortality was directly related to number of trees per acre and presence of dwarf mistletoe, but not to site index, elevation, and percent Douglas-fir in the stand."
