Interior Douglas-fir is a prevalent forest type throughout the central Rocky Mountains. Past management actions, specifically fire suppression, have led to an expansion of this forest type.

[David A Graham; Jack Mounts; Dewey Almas; Abstract. The Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), is a common defoliator of fir in the interior forests of western North America. It is one of four western species of Orgyia, but it is the only member of the group that occasionally reaches outbreak numbers while feeding exclusively on conifers.

Tussock moth populations too low to be detected by conventional means can erupt, however, into destructive outbreaks in Douglas-fir and true fir forests in just 1 or 2 :// Grand fir is susceptible to numerous insects.
The most troublesome are western spruce budworm, Douglas-fir tussock moth, western balsam bark beetle, and fir engraver beetle [71,80,]. Timing of, and slash disposal following, thinning are important precautions in avoiding fir engraver :// Interactions among fire, insects and pathogens differ between forests that have evolved with low‐intensity, frequent fires and those with high‐intensity fire regimes (Martin, ).

Fire, insects, and diseases are natural, integrated components of western forests in North America (Martin, ; Harvey, ).The recurring disturbances they cause are essential to creating and maintaining these forests (Hessburg et al., ).The combined effects of fire, competition for light and water, and native forest insects and pathogens have interacted for millennia to.
