Miner Creek area, Whitman National Forest, near Sumpter, Oregon. ().jpg 1, × 1,; KB. Localized populations of bark beetles typically prefer weakened or stressed trees; however, under epidemic conditions they attack even healthy trees. Common bark beetles in Arizona include: Pine Engraver beetles (Ips species) and Douglas-fir, Mountain, Red Turpentine, Roundheaded, Southern, Spruce and Western pine beetles (Dendroctonus species).Location: Phoenix, AZ Ponderosa Pine. Ponderosa pine is well adapted to high temperatures and low moisture and is highly resistant to low-intensity fire. Although ponderosa pine is most common between 6, and 9, feet, it begins to appear on the landscape around 5, feet where prairies and shrublands transition into open ponderosa pine forests.

They are twisted and gnarly, with thick bark and great dead wood. Some artists graft shorter needles to the smaller trunks, though you can successfully gain short needles through time.
The mountain pine beetle is a true predator on many western pine trees because to successfully reproduce, the beetles must kill host trees. They typically kill trees already weakened by disease or old age, but even a healthy tree’s defensive mechanisms can be exhausted when beetle numbers are at epidemic levels.

Ponderosa pine forests are especially susceptible to fires due to the extreme flammability of the foliage surrounding them on the forest floor (Cromack, ). The Ponderosa pine itself, is considered to be fire resistant, and is only damaged when the fire “crowns” (burning at canopy height) and 60% or more of the tree is destroyed ().
