|Ponderosa pine near Sisters, Oregon|
Most of us in the Pacific Northwest are familiar with the ponderosa pine. Just the mention of it brings to mind its long needles and distinctive, golden bark. But where do you picture these pines growing? Most likely it’s east of the Cascade Mountains, perhaps around Bend. So, it might surprise you to find out that ponderosa pine is also native to Oregon’s Willamette Valley. The ponderosas of the Willamette Valley are adapted to the wet conditions found west of the Cascade Mountains. Even more surprising, these natives are better adapted to wet areas than the Douglas firs that grow in the valley. I remember that we had two large ponderosas growing in a particularly wet area on the farm where I grew up northwest of Eugene. Although I didn’t know a ponderosa from a pond-lily at the time, I remember the distinctive look of these trees.
