You can find most of the native conifers of the
Northwest at Hoyt
Arboretum in Portland. To reach the Arboretum, take the
exit from Highway 26, drive up Knights Blvd past the Zoo, and turn
Fairview Blvd. The Visitor Center parking is 500 feet on the right.
The labels on the trees in the Arboretum make it easy to
identify each conifer. The
difficulty is finding the native conifers among the hundreds in the
conifer collection. The map below shows the location of the native
2-mile route marked in red passes all 18 natives of northwest Oregon
and several of the other conifers native to the Pacific Northwest.
You can find the
common low-elevation natives (Douglas fir, western hemlock, grand fir,
and western red cedar) growing at multiple locations.
