In November 2008, I made my first trip to Papoose Lake in the Trinity Alps Wilderness. That trip inspired my first blog post which evolved into Field Notes From Plant Explorations. This first post was more about geology than plants because of the unique geologic character of the Papoose Lake Basin.

This month, almost 15 years later, I returned to Papoose Lake to conduct vegetation surveys as part of our Klamath Mountains Vegetation Mapping Project. In many ways the basin is the same but in others changes are afoot. What follows are some reflections on 15 years of blogging through the eyes of a Klamath Mountain lake basin.
In 2010, I first found this tree while backpacking through the Trinity Alps Wilderness in far northern California. Just last week, thirteen years later, my son Sylas and I returned with tools to officially measure and nominate this tree. While points fell just short of the overall champion, it is the second largest foxtail pine known and the largest of the subspecies of the Klamath foxtail pine (Pinus balfouriana subsp. balfouriana).
“Whether old or young, sheltered or exposed to the wildest of gales, this tree is ever found irrepressibly and extravagantly picturesque and offers a richer and more varied series of forms to the artist than any other conifer I know of.”
−John Muir

The following excerpt is from my book Conifer Country. I was inspired to publish it here after a recent trip with my son to visit and measure the Klamath Mountain champion foxtail pine. After this trip, the foxtail pine is his favorite tree species too 🙂

California’s endemic foxtail pines have established two esoteric populations abscinded by nearly 500 miles of rolling mountains and deep valleys. The species was first described by John Jeffrey near Mount Shasta in 1852 , which was most likely a population near Mount Eddy or in the Scott Mountains. Later, this species was discovered in the high elevations (9,000’-12,000’) of the southern Sierra Nevada. The ecological context of Klamath foxtail pines in the Klamath Mountains differs drastically from that in the Sierra Nevada due to the divergence of these populations in the mid-Pleistocene. Though separated over one million years ago, both subspecies exhibit a radiance and individuality for which I honor them as my favorite conifer.
With separation in space and time, divergence—including cone orientation, seed character, crown form, foliage, and even chemistry—has occurred between the two subspecies. Another reason for these variations are genetic bottlenecks that have been promulgated by spatially restricted microsite adaptations, particularly in the Klamath Mountains . Northern foxtail pines (var. balfouriana) are isolated on sky islands—local mountain tops and ridgelines—from 6,500’ to 9,000’ in the eastern half of the Klamath Mountains. By my count there are 16 isolated sub-populations each consisting of one to several isolated mountain-top populations, except in the Trinity Alps where they are locally common in the more contiguous high elevations. On these sites, proper geologic, topographic, and climatic conditions have offered synergistic alliances with shade-tolerant and faster-growing firs and hemlocks.
I learned about this project in 2014 and have been following it closely ever since. In late April, 2020 my friends Justin Garwood, Ken Lindke, and Mike Van Hattem (with other co-authors) published the first definitive paper on glaciers in the Klamath Mountains. While the news is bleak, their diligent research documents the changes in the Klamath for hundreds of years through the eyes of the highest peaks and watersheds in the range. Please enjoy the summary that follows.

Green plants are considered autotrophs because they photosynthesize—making sugar from water and carbon dioxide. The world of heterotrophic plants is complicated but all have moved away from total energy production from photosynthesis toward obtaining organic carbon either directly from other living beings or through a parasitic relationship with a fungus. Heterotrophic plants include directly parasitic and mycotrophic forms. The conifer forests of the western United States nurture an exceptional diversity of heterotrophic plants and the Klamath Mountains may have the most heterotrophic plants in the western United States!
