In Oregon, the American three-toed woodpecker tends to use higher-elevation forests; however, forest type may not be as important to this species as the presence of bark beetles.
Nests are often fairly low; nest trees are often smaller in diameter than those used by other cavity nesters. Habitat requirements may include trees with heartrot for nesting and high densities of bark or wood-boring beetles.
It is rare and local, particularly near and west of the Cascade summit, often near high-elevation lakes or beetle outbreaks. American three-toed woodpeckers are Oregon Conservation Strategy Species in the Blue Mountains and East Cascades ecoregions.
