Relearning the Southern Siskiyous

I am slowly learning about some of the shortfalls my training as a western scientist has had on my ability to interpret vegetation communities of the Klamath Mountains. What I am learning, that was never properly taught in my schooling, is that everything we see today in the Klamath Mountains was affected, to some degree, by long-term human habitation over the past ~9,000 years. For example, up north in British Columbia’s coastal temperate rainforest Fisher et al. (2019) found that the plant communities around village sites had different plant assemblages than control sites and were dominated by plants with higher nutrient requirements and a cultural significance. Consider this next time you look at an oak woodland on a river bench

Another major misconception taught in western science is the description of the assumed wild and wilderness as absent of human impact–when this is far from the truth. Much of what we have designated as wilderness was sculpted by Native People’s stewardship. For example, numerous travel routes were maintained for securing basketry, medicine, food resources, or reaching ceremonial sites (see map below).

Serpentines of the Salmon Creek-Mattole River Divide

Original Publication DATE: 1/19/2013

On the divide between the South Fork of the Eel River and Mattole River exists a place I had repeatedly mapped while creating the images for for Conifer Country. I knew there was a small patch of serpentine in this isolated location because of the occurrence of two tree species that are uncommmon on the North Coast outside of the Klamath Mountains proper. In the past I had asked regional ecologists about this location and the common response was “its is somewhere out near the Mattole River.” I knew that already, but how could I find the exact location?

The mystery was solved when Kyle and Dana Keegan, offered a “visit to the Salmon Creek watershed which is a tributary of the South Fork Eel. We have an especially unique diversity of plants and trees here due to a complex melange of geologic features with what we believe to be the largest, most westerly stand of Jeffrey Pine in the state, as well as vast stands of Incense Cedar. Kinda like an isolated westerly chunk of the Klamath Siskiyous–with it comes a whole host of serpentine endemics.”

Yes please…

Parque Nacional – Sierra de San Pedro Martir

Original Publication DATE: 6/7/2011

This mountain range had been a place in my dreams for many years. I had heard about its rich conifer forest, that many of the conifers (and other plants of course) common within California reached their southern range extension here, and that a natural fire regime had been ‘maintained’ by mother nature. This was an intact a forest–in as natural a state–as we 21st century explorers might hope to find. The mountains themselves are part of the Peninsular Ranges which I was quite familiar with, having lived in the San Gabriel’s for many years.
