A decade ago, folks in northern states such as Minnesota, South and North Dakota, Montana, Wyoming and Idaho were watching large swaths of their pine forests die off due to invasive pine beetles. The pine beetles bored beneath the bark of pine trees and introduced a fungus and larvae which weakened and then killed the :// Fir engraver and Douglas-fir beetle numbers were monitored during and after an outbreak of the Douglas-fir tussock moth.

Douglas-Fir Beetle Dendroctonus pseudotsugae Key Wildlife Value: The Douglas-fir beetle creates Douglas-fir snags, generally preferring larger trees above 30 to 36 cm (12 to 14 in) dbh.
Trees are killed individually and in groups. Canopy gaps and eventually concentrations of down wood result when mortality is :// Douglas-fir under attack. Attacks in stand-ing larch are always unsuccessful, while those in freshly felled larch are usually successful and brood emergence is equiva-lent to that in Douglas-fir.
Douglas-fir beetles normally kill small groups of trees, but during outbreaks tree groups are not uncommon (fig. Douglas-fir beetle outbreak in the Bighorn Mountains of northern Wyoming (Figure 1).
While the beetle typically reproduces in stressed trees, no stressor such as blowdown or fire is evident to have initiated this outbreak. The objectives of this study are to: 1. Quantify the severity and impacts of Douglas-fir beetle infestations at Key Wildlife Value: The Douglas-fir beetle creates Douglas-fir snags that are 30 - 36 cm ( in) dbh and larger.
When it colonizes trees greater than 51 cm (20 in) dbh, the Douglas-fir beetle contributes to the “large snag” component of a stand or :// Forest Insect and Disease Identification and Management Training Manual, USDA, Forest Service, R-1, Timber, Coop.

Within-stand distribution of mortality was examined in affected stands using geostatistical techniques. A 10 × 10 m grid was established in two 4-ha study sites. Live and beetle-killed host basal area was measured at each node. In a ha. The spruce beetle,Dendroctonus rufipennis (Kirby), is the most significant natural mortality agent of mature spruce.
