Characteristics:
Habitat:
Range:
It may be found in the Columbia River Gorge between the elevations
of 100'-3000' from the western approaches to the gorge (where it is very common)
to the eastern end of the gorge where it is seen rarely.
In the Columbia River Gorge, it is most common at lower altitudes
(below 3000') but may be found at least as far east as Biggs Junction where
there is water (typically atop a spring or along a stream) where birds have
spread the seeds with their droppings and there is enough moisture for the seeds
to germinate.
