A Tree at Risk — Ponderosa Pine or (maybe) Rocky Mountain Yellow Pine

This winter, warm and dry as it might be, I have written about the evergreens, or plants that keep their leaves through the winter. Of the trees that are evergreen and native in or near Golden, we have previously reviewed the Rocky Mountain juniper — Juniperus scopulorum Sarg. — and the Douglas fir — Pseudotsuga menziesii (Mirb.) Franco.
The third native evergreen tree found in Golden is the ponderosa pine — Pinus ponderosa Douglas ex Lawson & C. Lawson — found on the high places around Golden, including North Golden Hogback, Tin Cup Ridge, and Apex Park. There is one tree on top of North Table Mountain near the radio tower, although it is unclear whether it was planted.
The ponderosa pine was one of several trees that David Douglas (1799-1834) introduced into cultivation in England following his second expedition to the Pacific Northwest. Another of Douglas' introductions was the Douglas fir – Pseudotsuga menziesii (Mirb.) Franco. Ponderosa pine was described by Peter Lawson and his son (Lawson & Son, 1836) from plants grown from Douglas’ seeds in pots at Lawson’s Agricultural Museum in Edinburgh, Scotland. This was supplemented by a larger specimen growing in the Caledonian Horticultural Society's Gardens, also in Edinburgh, Scotland. Lawson gave our tree the specific name ponderosa because of the density of the “… timber said to be so ponderous as almost to sink in water …(ibid.)”
Several varieties of P. ponderosa have been described, and those in Colorado are generally known as variety scopulorum Engelmann (Brewer, Watson, and A. Gray, 1880, vol. 2, pg. 126). John G. Lemmon (1897), though, wrote that our Rocky Mountain tree was its own species and proposed the name Pinus scopulorum Lemmon. Some recent genetic evidence supports Lemmon’s assertion (Willyard, et al., 2017). In short, whether our Front Range trees are a variety of the ponderosa pine or a distinct species remains debated, but recent genetics support species status.
“Scopulorum” may sound familiar, in part because we recently wrote about our local large juniper – Juniperus scopulorum Sarg. In a plant name, the Latin term “scopulorum” means "of the cliffs or rocks" or "of rocky places." There are eleven plants that live in Colorado that have scopulorum in some part of their name (see list below).
If we treat our “ponderosa pine” as a separate species from the ponderosa pine of the Pacific northwest, what common name should we use for it? As it happens, Lemmon (1897) had a suggestion, attaching the common name “Rocky Mountain yellow pine” to his scientific name of Pinus scopulorum Lemmon.
Regardless of the name we humans apply to our tree, the tree is host to the mountain pine beetle (Dendroctonus ponderosae), a native insect whose outbreaks, often worsened by climate change, cause massive tree mortality by clogging the tree's vascular system with blue stain fungus (CSFS, 2025). Dry and stressed trees produce less resin, which is the natural defense to beetles. A lack of extreme cold periods in spring or fall has also allowed pine beetles to continue to spread. If Colorado experiences a relatively warm and dry winter followed by a warm, dry spring, the beetles will expand rapidly.
While eradication of the mountain pine beetles is unlikely, the state has formed a task force to address the beetles’ potential impact to watersheds, recreation and infrastructure. The recommendations will include wildfire risk-management strategies, assistance to help landowners pay for wildfire and beetle mitigation, expansion in the use of beetle-killed timber, and funding for research on beetles (Schmelzer, 2025).

Golden History: Golden's Water Supply

Excerpt from photo Z-12056, Denver Public Library Western History Collection – Water pumping station circled and magnified – enlarge
Click to enlarge
For nearly a century, Golden’s water supply was a subject of constant concern and discussion. Sparkling clean when settlers first arrived in 1859, Clear Creek soon became polluted with effluent from upstream mining operations. The water pumped from the Creek into Golden homes was, at times, muddy, full of chemicals, and bacteriologically questionable.
Our water quality saw a huge improvement in 1904, when we established a “gravity fed” water supply with water piped over several miles from Beaver Brook. That water, which did not have upstream polluters, was called “sparkling clean” and considered “pure and wholesome.”
Unfortunately, in many years Beaver Brook ran low and our reservoir on Lookout Mountain went dry. Sometimes the pipes from the reservoir froze, leaving the town without running water. When that happened, our old pumping station was fired up, and we reluctantly turned back to using Clear Creek water.
88 Years Ago
The January 27, 1938 Colorado Transcript was providing decidedly mixed messages about the water available from Golden taps. This was 15 years before the water treatment plant was built, and the City was going through one of its frequent pumping-water-from-the-Creek periods.
The Transcript included an article with the headline “Tests Show Golden Water Pure and Safe.” In smaller type below, it added “Boiling Is Suggested By Council Only As Precaution.”
The State Sanitary Engineer had tested the water and pronounced it to be free of contamination, clear, and without odor. Nonetheless,
It has been suggested by the city council, as a matter of precaution, that all water used for drinking and cooking purposes be boiled during the period of the operation of the emergency pumping plant.
This cycle finally ended in 1953, when the City built a water treatment plant. The new plant included settling ponds, filters, and chemical water purification, and allowed us to use Clear Creek water and have excellent water quality.
