Santa Fe national forest Supervisor Shaun Sanchez has a lot on his plate trying to rebuild credibility after the agency’s 2022 intentional burn ignited a massive wildfire that so far as cost the taxpayers over $4 billion. Drinking water supplies in the affected communities are contaminated with toxic heavy metals likely caused by the blanket use of fire retardants. Post fire flooding resulting from increasingly intense summer thundershowers continues to erode adjacent farmland and ancient irrigation systems.
The normally bustling Santa Fe forest headquarters was mostly empty when a colleague and I visited last week. More than 80 percent of the recreation staff is gone. Around a conference table that seemed too big we discussed the weather and shared hope that this winter’s first snow would permit the burning of thousands of debris piles that have built up from years of forest clearing. However, warm winds soon melted most of the snow creating another of the seemingly endless delays.
In my more than four decades of forest activism in the Southwest, Shaun is probably the most engaging Supervisor I’ve encountered. He listens and asks good questions. He’s the first to have grown up in the unique mix of cultures in northern New Mexico. Instead of just passing through, he has a deep sense of belonging to this place.
Our meeting concerned the fate of the vulnerable white pines. It’s been more than a decade since a committee of scientists recommended that a refugia be established in the Santa Fe Municipal Watershed to protect a self-replicating population of white pines still free from the century-old white pine blister rust. Despite years of pleading nothing has been done and millions of white pines were needlessly cut, piled and burned in fuel reduction projects.
New Mexico’s intermingled population of southwestern white (Pinus strobiformis) and limber pines (Pinus flexilis) is unique. Recent research has identified high levels of resistance to blister rust from seed collected in the Lincoln, Cibola and Santa Fe national forests. After 7.5 years of experimental exposure to blister rust spores, three populations had a greater than 70% survival rates representing perhaps the highest level of resistance documented to date in a North American white pine species. Preserving this diversity is essential to white pine survival.
Ecologists in the 1920s were critical of the Forest Service when it told landowners to cut down the last American Chestnuts for their valuable wood as these majestic giants were being eliminated from the eastern forests by chestnut blight. The genetically resistant “redwoods of the east” were likely lost forever when the agency ignored this advice. In the 1960s, rust resistant western white pines were removed from the forests of Idaho and Montana when the cut was accelerated to extract their valuable timber before most of them succumbed to the pathogen. No need to repeat this sad story in the Southwest.
Instead, update the Santa Fe forest plan to keep up with the current science. It’s not big step — both New Mexico’s Cibola and Arizona’s Apache-Sitgreaves forest plans protect white pines — and the regional office (what’s left of it) wants forest plans in the Southwest to be consistent.
What will Washington say? Although white pines are not a commercial species on the Santa Fe, Trump officials will likely see any protection as a needless distraction. Uncommon courage is needed to stand up to these timber bullies.

I asked Sam for some links, and Johnson and Sniezko_2021_Quantitative disease resistance to WPBR is the resistance work he is referring to, by one of my old buddies at Dorena.
Here’s the Santa Fe Watershed Management Plan (funded by CFLRP) and the key paragraph p. 18.
Continue to protect Southwestern white pine. During planning of restoration treatments a concern was expressed for the fate of Southwestern white pines in the municipal watershed, because populations have suffered in the West in recent years due to the exotic white pine blister rust. White pines in the municipal watershed have been reproducing successfully in spite of the threat of blister rust and thus the municipal watershed has been identified as a possible sub regional refugia for this tree species. The protection of southwestern white pines should continue to be an objective throughout long-term prescribed burning maintenance.
I suppose the word should be “refugium’ since they are speaking of a singular place. It does make me wonder how a series of refugia would be designated (by whom) and managed, since I don’t think there are forest geneticists in R-3. And technically, I don’t think two contractors are a “committee of scientists” nor are they geneticists..so.. not to get be defending disciplinary boundaries here..
Here were the other questions I had:
1. “after the agency’s 2022 intentional burn ignited a massive wildfire that so far as cost the taxpayers over $4 billion.” If this is Hermit’s Peak/Calf Canyon, I thought that Calf Canyon was started by a resurgent burn pile and Hermit’s Peak by an escaped prescribed fire, which were I guess two “intentional burns” if you want to characterize a resurgent burn pile that way.
2.
New Mexico’s intermingled population of southwestern white (Pinus strobiformis) and limber pines (Pinus flexilis) is unique. Recent research has identified high levels of resistance to blister rust from seed collected in the Lincoln, Cibola and Santa Fe national forests. After 7.5 years of experimental exposure to blister rust spores, three populations had a greater than 70% survival rates representing perhaps the highest level of resistance documented to date in a North American white pine species. Preserving this diversity is essential to white pine survival.”
The referenced genetic study was only of SWP. Here is what the study says, not three populations, but three families of of the 40 sampled.
We assess progeny arrays from 40 P. strobiformis families (1873 seedlings), originating from three populations, inoculated with C. ribicola. Subsequently, the seedlings were assessed for signs, symptoms and resulting impact in a common garden trial over a 7.5-year period to determine the types and frequency of
resistance in a portion of this species’ range. There was a high incidence of both stem symptoms and mortality in the P. strobiformis families tested, and families ranged in survival from 0 to 84.6%. Three families had >70% survival, representing perhaps the highest documented QR to date in a North American white pine species.
But the fact that SWP is relatively rare would be a reason to protect it. Not like sugar pine, WWP or even limber.
So a logical thing would be to collect cones from all the SWP and test them, then collect seed from those trees for planting. That’s what we did for sugar pine, western white pine, and whitebark.
Here’s a link to everything you might want to know about SWP from the fire effects information, including fire ecology.
3. “Ecologists in the 1920s were critical of the Forest Service when it told landowners to cut down the last American Chestnuts for their valuable wood as these majestic giants were being eliminated from the eastern forests by chestnut blight.The genetically resistant “redwoods of the east” were likely lost forever when the agency ignored this advice.” I asked Sam for a citation for this, as I had never heard it. Many Weeks Act eastern forests had been cut over by logging companies, e.g. the Monongahela. Also, I’m also not sure that there was an ecological science per se in the 1920’s.
4. “In the 1960s, rust resistant western white pines were removed from the forests of Idaho and Montana when the cut was accelerated to extract their valuable timber before most of them succumbed to the pathogen.” Again, there’s a great deal more to this story according to this 1999 GTR “White pine in the American West a Vanishing Species”..
Starting in 1880, the farreaching western white pine forests became the principal target for logging. The Inland Northwest’s first timber mill was built in 1880, and the second followed in 1882. Logging removed massive white pine groves for more than 100 years. After the 1910 fire episodes and the onset of logging, the young trees then fell victim to yet another challenge: white pine blister rust, an Asian fungus introduced to western North America in 1921 by way of Europe.
Probably some of you remember people who had gotten their start in the FS with Ribes eradication.
This was what the authors saw happening in 1999..
On Federal lands, harvest rates that create openings seem headed for such low levels that it appears questionable whether significant white pine restoration can take place. Without some sort of disturbances that create openings, forest succession will lead to the replacement of white pine by other species.
5. Trump? “timber bullies” on the Santa Fe?
It would be helpful to know what the SF is not doing (more at the prescription level), that the other forests are doing to protect SWP. And maybe someone has a more up-to-date range map?
