Trees of Klamath National Forest along the Klamath River.
River Manager at Happy Camp in Klamath National Forest, summarizes what trees
you will see is you follow the river corridor along the Klamath River:
"Starting from interstate 5 and heading west floating on the Klamath River
you will encounter juniper and sage blending into the mixed forest of ponderosa
pine, oregon white oak, and black oak covering the hillsides.
Further west the mixed evergreens take over, ponderosa pine, douglas fir,
sugar pine, incense cedar along with pacific madrone, canyon live oak, bigleaf
maple, and tanoak. Understory trees include redbud, pacific dogwood, hazel.
Riparian species include several species of willows, red alder, oregon ash,
cottonwood, bigleaf maple, fox grape, and blackberry. Of course we can not
forget, poison oak. It is abundant in the river canyon.
If you go far enough west you will eventually encounter the redwood forest
(which here includes red and white alder) near the Pacific Ocean and the mouth
of the Klamath River."
