Bark Beetle Infestations of Lodgepole Pine Following a Fire in South Central Oregon

After light ground fires smolder through climax lodgepole pine (Pinus contorta var. murrayana) stands, Dendroctonus ponderosae attacked a high proportion of unscorched and lightly fire-damaged trees; Ips pini preferentially attacked the moderately to heavily fire-damaged trees. Discriminant analysis showed that percent root kill and tree diameter correctly classified 74% of the D. ponderosae infested trees; I. pini attacks were negatively correlated with tree diameter and positively correlated with percent basal kill and these two variables correctly classified 84% of I. pini infestations. Percent root kill was the most important fire related variable associated with combined Ips and/or Dendroctonus attacks. The influence these light fires have on lodgepole pine stand dynamics is also discussed.
