Yellow Pine Visual Aid

(intended to supplement yellow pine definition and help forestry technicians doing walkthroughs and timber marking on Dutton Hill accurately determine what is and what is not a yellow pine)

Yellow Pine/Pre-settlement/Old Tree: mature ponderosa pine approximately 150 years or older; bark ranges from reddish brown, shading to black on top with moderately large plates between fissures to reddish brown to yellow, with very wide, long, and smooth plates; tops range from pyramidal or rounded (occasionally pointed) to flat (making no further height growth); branches in the lower third of the crown are generally drooping, and in older trees, are often large, gnarled or crooked.

Yellow pines (very clear) – very yellow bark, with long, smooth plates

Yellow pines (fairly clear) – yellow bark with fairly large plates, though plates not quite as long and smooth as previous picture; branches aren’t very large, but still drooping in lower third of crown

Yellow pines (borderline) – bark reddish brown, turning yellow, not as obviously platy as in previous pictures (especially tree on left), but larger plates are developing between fissures; lower branches are large and drooping (partly due to mistletoe but still enough to be a yellow pine)

Transitional blackjacks (borderline yellow pines) – bark beginning to turn reddish brown, but no real plates developing; branches in lower crown horizontal to angling slightly upward and not very large.

Transitional blackjacks (not borderline yellow pines)– bark beginning to turn reddish brown, but no real plates developing; branches in lower crown horizontal to angling slightly upward and not very large.
