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.
Select Forest Pathogens of California’s Klamath Mountains
Forest Pathogens often go unnoticed while exploring, but offer an exceptional window into the intricacies of forest ecology when better understood. I created the free document linked below in 2011 while in Grad School at Humboldt State. Forest Pathology was one of the more interesting classes I took while turning Conifer Country into my thesis for a Master’s Degree in Biology. Most of the information for this document was taken from Terry Henkel’s lecture notes as well as from internet and book sources–all cited within the document. I was recently reminded of this creation because of the October weather that has dropped unprecedented amounts of rain and nurtured fungal growth across Northwest California.
I have used various approaches which always involve careful map study, perusing the pages of hiking guides, and most importantly for me—studying field guides. As I get older, choosing a hiking destination is becoming more critical, with so much to see and even more to learn.

Over time, I have gone about choosing a hike based more as a destination for discovery before any other factor. I think I first caught the hiking-for-natural-discovery bug while selecting a backpacking route exclusively to see condors in the Sespe Wilderness of southern California. When I moved to Humboldt in 2002, I graduated from bird destinations to plant exploring as I began searching out rare and unusual conifer species in our local mountains. This regular wilderness sideline blossomed into a Master’s Degree from Humboldt State University when I published my first book Conifer Country: A natural history and hiking guide to the conifers of northwest California in 2012. For 10 years I hiked to find and understand trees. These trees, and the places they grow, helped me develop a deeper passion for place and an understanding of the unique natural history of northwest California.
One of the most interesting geologic stories in western North America is told by the ultramafic rocks that were formed deep in the ocean floor. As the Pacific Plate collided and dove beneath (subduction) the North American Plate, the bottom layers from deep oceanic mantle were scraped (obduction) onto the North American Plate. These depositions are referred to as ophiolites and the Klamath Mountains present some of the most extensive examples on Earth.

I was recently asked by KHSU, here in Humboldt County, to write a two minute script for their Sound Ecology series. I chose to write about the conifers of the Klamath Mountains. I hope you enjoy this piece and are planning your next adventure into this botanical wonderland.
Here are the activities I will be a part of in the coming months, please join me!
My first adventure in the Klamath Mountains was in February 2003, several weeks after moving to Humboldt County. Here is an excerpt from the introduction of Conifer Countryabout that trip:
After poring over maps, studying the ridges, passes, and creeks, I filled my backpack with winter gear, food, and a copy of David Rains Wallace’s The Klamath Knot. The adventure was on….The next four days found me spending time staying warm, staying dry, differentiating between the conifers, and reading and re-reading The Klamath Knot. The Knot is a “Klamath cult classic” that weaves the myth of giants with the mysterious quality of ancient forest evolution—surely this was the perfect companion for my first trip in the Siskiyous.
I fell in love with the mountains that fateful February week, deep in the Siskiyous. I read and re-read The Klamath Knot as the rains poured down on me, the nearby creeks swelled, and the mountain passes accumulated snow. I gained a deeper respect and understanding for this wild place too—because of David’s mountain tales that wove natural history and evolution into a place-based book.
Today, it is with great fortune and excitement that I announce to my noble readers that my publishing company, Backcountry Press, is releasing a book by David Rains Wallace. Articulate Earth is a collection of 23 essays written over 30 years of Wallace’s career. The essays explore our relationship with nature—particularly that of the West—in its literary, scientific, and political dimensions. Please support independent publishing by picking up this book from our website or visiting your local independent bookstore—and then referring this book to friends.
