This chapter provides a synthesis and brief review of 11 Base Evaluation Monitoring (EM) projects and 7 Fire Plan projects in Arizona, Colorado, Idaho, New Mexico, Utah, and Wyoming. Base projects were distributed among the primary coniferous forest types in this region: spruce-fir, piñon-juniper, Douglas-fir, lodgepole pine, limber pine, and ponderosa pine. All but two of the Base projects were associated with bark beetle-caused tree mortality, the exceptions being a study examining the effects of a defoliating insect, Nepytia janetae, and a study assessing the occurrence, severity, and expanding distribution of the nonnative balsam woolly adelgid. Fire Plan funded projects were spread among Engelmann spruce, lodgepole pine, Douglas-fir, ponderosa pine, and piñon-juniper types. Six of these projects examined relationships between tree mortality, fuel accumulation, and fire modeling. The remaining project investigated the effects of prescribed burning on bark beetle populations.
