About this file
This document is a visual aid for identifying Yellow Pine trees, specifically ponderosa pines, intended to help forestry technicians accurately mark timber on Dutton Hill. The guide provides detailed descriptions and photographic examples of Yellow Pines at different stages of development, categorizing them into five distinct groups:
- Pre-settlement/Old Trees (150+ years): Characterized by reddish-brown to black bark with moderately large plates, pyramidal or rounded tops, and large, drooping, often gnarled lower branches. 2. Very Clear Yellow Pines: Feature very yellow bark with long, smooth plates. 3. Fairly Clear Yellow Pines: Have yellow bark with fairly large plates, less smooth than previous examples, and drooping lower branches. 4. Borderline Yellow Pines: Show reddish-brown bark turning yellow, developing larger plates, with large drooping lower branches. 5. Transitional Blackjacks: Bark beginning to turn reddish-brown with no real plate development, and lower branches horizontal or slightly upward-angling.

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.
