Metadata (Data about data or how the map was made)

In western Washington to the lower east slopes of the Cascades, but not known from the northeastern Cascades, found mostly in dry to mesic forest floors from sea level through the Canadian zone and occasionally in the Hudsonian. Highest elevations found in Cascades 5600 feet and Olympics 4850. Most records are from below 3000 feet.

Range included all regions in the west part of the state, excluding the Northeast Cascades. Core zones were all mid- to low-elevation forested zones within its range limits except for the driest forested zones. All Forests were good habitats except open forest in the driest forest zones. In mesic and wet forest zones, cuts and burns were adequate in the earliest seral stages and good in later, shrubby stages.
