Natural history
Ponderosa pine is a tree common to the foothills and canyons of the Colorado Rockies from 4600 to 9,600 feet with its full range encompassing much of the western United States and Canada where it is among the most widely distributed of pine trees. Ponderosa pine tends to be tall with a broad conic to rounded crown. Its bark is reddish-brown with deep irregular furrows that outline large plates of bark, which have a distinctive butterscotch- or vanilla-like scent.
Pinus ponderosa is evergreen with long (10-17 cm) needle-shaped leaves typically in fascicled bundles of 3. Like all pine trees, it produces both pollen and seed cones with the pollen-producing cones being much smaller than the seed-producing cones, which are often conspicuously strewn about the ground around a Ponderosa pine. Pinecones consist of many seed-bearing scales. In Ponderosa pines, the outer tip of these cone scales each have a distinctive sharp spine that aids in recognition of this species. Just remember “prickly Ponderosa.”
In the Colorado Rockies, Ponderosa pine suffers from much “beetle kill” caused by the Mountain pine beetle (Dendroctonus ponderosae), and in the Southwest, is often afflicted by parasitic Dwarf mistletoe (Arceuthobium vaginatum ssp. vaginatum). Pinus ponderosa is one of many trees that have a mutualistic relationship with underground networks of mycorrhizal fungi. These fungal networks play a crucial role in local food webs and aid in nutrient absorption by trees, nutrient cycling, and soil ecology.
Human history and use
Ponderosa pine has a long history of use as a building material among regional Indigenous Peoples. Timbers of ponderosa pine, spruce, and fir were used by the Ancestral Puebloans in the construction of the great houses at Chaco Canyon. More recently, ponderosa pine has been utilized as a building material by both the Hopi and Navajo. A tea made from pine needles has reportedly been used as a diuretic and expectorant, to treat coughs and fevers, and as a ceremonial emetic. Pine pitch has been applied topically to treat wounds and skin conditions.
