I have been fascinated for a long time with the conifers of the Klamath Mountains. While there are many places across the region that have a high density of conifer species, one of the hotspots is in the Russian Wilderness in an area known as the Miracle Mile. It has a long, storied history of discovery, research, conservation, and recreation.
If you visit, tread lightly and leave no trace. Day hiking is the best way to see it and preserve the unique natural features of the area. What follows is a summary of my presentation during the COVID-19 pandemic.
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.
In conjunction with the Klamath National Forest and the California Native Plant Society Vegetation Team, I completed a mapping and inventory project for Pacific silver fir (Abies amabilis) in California. The first part of this project was along the Siskiyou Crest, near the Oregon-California border. This post is about the populations in the Marble Mountain Wilderness.
In 2016 I embarked on a mapping and inventory project for yellow-cedar (Callitropsis nootkatensis) in California. At the time, I called yellow-cedar California’s rarest conifer. In 2019, new discoveries on the north slopes of Copper Butte and Preston Peak brought the total hectares of yellow-cedar in California to ~21 hectares. With this new data, and that collected in this project, we now know Abies amabilis is California’s rarest conifer*! See table below for stand data summary.
*This excludes the neoendemic California cypresses.
I first visited this area in 2004 when my friend Jay and I attempted an ambitious loop starting from the Wooley Creek Trailhead, to the headwaters at Wooley Lake, back to Hancock Lake, and then laboring along the non-existent trail on Steinacher Ridge back to our car. This was the first major hike I took in the Marble Mountain Wilderness and my encounter with Pacific silver fir (Abies amabilis) around the Diamond Lake – English Peak region inspired the writing of my first book, Conifer Country.
Exploring upper Copper and Indian creeks for yellow-cedar
I have been mapping and inventorying yellow-cedar (Callitropsis nootkatensis) in California for the past four years. This process could have been much more efficient if it wasn’t for the 2018 Eclipse Complex and the 2019 Natchez Fire (more below) that virtually closed the Siskiyou Wilderness for the past two summers.
Successful surveys before this year have doubled the previously known area of this rare conifer from approximately 5 hectares in 2015 to 11 hectares by 2018. One of the largest gaps in surveys was within upper Indian and Copper creeks in the Klamath River watershed. I predicted this is where the largest stands of the species would be–little did I know how large an area I would find.
On a recent trip into the Marble Mountain Wilderness to map and monitor whitebark pine (Pinus albicaulis) on the Klamath National Forest, I found myself near Isinglass Lake. I had read that the only population of great sundew (Drosera anglica) in the Klamath Mountains was documented here in 1972. I knew there was a Klamath Mountain peat bog to be found.
The Warner Mountains are a north-south trending fault block range in the northeastern corner of California, extending northward into Oregon. The length of the range is approximately 90 miles, with the northern California portion bounded by Goose Lake on the west and Surprise Valley on the east. In California, elevations range between 5,000-9,897 feet (on Eagle Peak). In the High Grade district, which is the extreme northern limits of the Warners in California, the range has a fairly even crest of 7500 feet, reaching an elevation of 8290 feet on Mount Bidwell. This is the area where I spent four days mapping and monitoring whitebark pine (Pinus albicaulis) for the US Forest Service.
The geology of the region is complex and compelled me to understand it better. Bedrock consists of sedimentary rocks of the Oligocene overlain by rhyolitic to basaltic volcanic rocks of the Miocene. The basal andesite is overlain by rhyolite and glassy rhyolite, which are in turn overlain by basalt flows. There are valuable minerals and gems found in this area that have justified a long-standing history of mining. Gold was the first and major extracted mineral soon followed by opals, petrified wood, and even obsidian. The range is a complex assemblage of interesting rocks for sure which help sculpt the regional ecology.
It is no secret that the Siskiyous are my favorite place in the Klamath Mountains. I have spent many days and hiked numerous miles across this region. The Bigfoot Trail travels the entire crest of the range as well.
In early August 2017, lightning ignited a series of fires first named Oak, Cedar, Clear, and Prescott. These fires later grew together and were combined into the Eclipse Complex. Over the next month, approximately 100,000 acres burned in and around the Siskiyou Wilderness. Between last October and now I have had reason to visit much of this area for work and play. What follows are some of the pictures I have taken.
The coastal lowland forests receive the most annual rainfall of anywhere else in the Klamath Mountains. From the north in Oregon the Coquille, Rogue, and Illinois rivers drain southwest Oregon and the Smith River country is California’s only temperate rainforest. The rich soils, temperate year-round growing season, and high rainfall (often over 100 inches) nurture these impressive forests.
Klamath coastal lowland forests are typified by dense, closed canopies on well-developed soils (sometimes serpentines). The dominant tree species have high colonizing abilities, long life, and a wide ecological tolerances to environmental conditions, including dry summers with occasional persistent fog. These forest thrive below the snow belt on the extreme western slopes of the Siskiyou Mountains. Species like Douglas-fir (Pseudotsuga menziesii) and Port Orford-cedar (Chamaecyparis lawsoniana) secure the highest place in the canopy, often approaching 300’. A second canopy forms one hundred feet below and includes species like tanoak (Notholithocarpus densiflorus) and madrone (Arbutus menziesii) where they share an understory with coastal specialists like salal (Gaultheria shallon) and evergreen huckleberry (Vaccinium ovatum). With the high volumes of rain that falls each winter, banks of coastal rivers and streams are frequently disturbed and then repeatedly pioneered by red alder (Alnus rubra).
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.
I have begun a collaborative mapping and inventorying project for yellow-cedar in California this summer. The species is a CNPS Inventory of Rare and Endangered Plants on list 4.3 (limited distribution) in the state, with only a handful of known locations. The majority of the stands are on the Klamath National Forest but a few are also on the Six Rivers. Over the course of the summer I will be visiting a number of these populations and collecting data on stand health, reproduction, and plant associates. I made the first stop of the summer at the Bear Peak Botanical Area.
I recently started a citizen science project with 5 classes of high school biology students from Fortuna, California. The plan is to combine their observation skills with the technology offered by iNaturalist. Each month they will visit Rohner Park and record data on a chosen spot in the forest–looking for plants and animals as well as changes in canopy and ground cover. As they become more proficient in species ID, students will also upload observations to our iNatural Project ultimately creating a field guide to their local forest. We all know how much I like field guides…
My plan, over future visits to wilderness areas, is to start similar citizen science projects. The first attempt at this wide-ranging project began this week on a visit to the Bear Peak Botanical Area on the Klamath National Forest. I originally wrote about this area in my book Conifer Country because it is unique in many ways, including the populations of yellow-cedar found here. This species in common further north, but quite rare in California.
For me it is a time of rejuvenation and also my favorite season. With the shift of the California Current, rains begin to fall in California after a summer of drought. The high country along the Pacific Slope finds snow returning. While we retreat inside our homes, native plants and animals must adjust to the changes. Some birds migrate, mammals might hibernate, and some plants shed their leaves and “hibernate” for winter in their own way.
What follows is a journey across the Pacific Slope to four favorite fall hikes–excellent for colorful foliage. I’ve also included some of the plant species that will be found.
San Gabriel River National Monument
Blackrock-High Rock Desert National Conservation Area
Mount Linn–also called South Yolla Bolly Mountain–is the highest point in the Coast Range of northern California. It is located to the west of Corning but the area might as well be a world away from the population centers of the state; it is rarely noticed by travelers as they drive Interstate 5. Once off the interstate, scenic forest service roads still take nearly 2 hours to wind to the trailhead. I revisited this fine mountain in July of 2016 to set up a photo-monitoring plot along the Bigfoot Trail and took the time to also map the vegetation on the mountain–particularly the grove of foxtail pines near the summit. This is one of the smallest (12 acres) and most isolated groves for the entire species and one that I am very much concerned about due to climate change. Shasta firs are encroaching upon the trees as snowpack declines and temperatures warm. I was happy to see the trees doing well and many young foxtails sprouting up–just not as many as there are young firs.
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.
From the California Native Plant Society North Coast Chapter:
Explorer, writer, and educator Michael Kauffmann will lead us on a journey into the Transverse Ranges of southern California to explore the world of what John Muir called the steepest mountains in which he ever hiked. Michael’s explorations began because of a Bigcone Douglas-fir mapping and monitoring project he is leading in conjunction with California Native Plant Society, but these studies have allowed him to make more discoveries–from one of the world’s largest oaks to the most isolated grove of Sierra junipers in the world. Michael will take us on a photographic journey from the mountain tops to the river canyons across one of the nation’s newest national monuments.
Celebrating the Bigcone Douglas-fir of the San Gabriel Mountains
After nearly a month of travel through one of the gems of Southern California, I’ve had enough time to reflect on all aspects of the journey–including the wonders of the wilderness and forest, as well as the state of the region. The San Gabriel Mountains remain wild, in large part, because of isolation due to slope. John Muir called them the steepest mountains he ever hiked in! It seems to me that the forests here are doing as well as they are, while our climate is rapidly changing, because of this isolation in slope. Forest pathogens travel much slower through heterogeneous landscapes with mixed stands of trees. Many of the Bigcone Douglas-fir stands we visited were in isolated on slopes of greater than 50º. Isolation sculpts the ecology of the mountain’s biota in many ways, and makes life for Pseudostuga both easier and more difficult. That balance defines the ecological amplitude of many of the species on the California Floristic Province.
I’m still working on the full report for our findings, but in general it can be said that within region 1 of the map below, Bigcone Douglas-fir are not doing well. Elsewhere, they seem to be doing fine at the moment–especially if the species has been able to avoid high intensity fires. Reproduction is occurring at variable rates but they seem to like disturbed areas, like landslides, which the San Gabriels have no problem offering.
Exploring the San Gabriel Mountains National Monument
In my search to understand Bigcone Douglas-fir (Pseudotsuga macrocarpa) within the Angeles National Forest, I found myself in secret canyons and along steep hillsides that few people have ever explored. I thus took it upon myself to document more than just our selected data plots for Bigcone. In previous posts, I’ve shared some of the large angiosperms I’ve run across. Here is the documentation of the second largest Pseudotsuga macrocarpa yet measured — a record Bigcone Douglas-fir.
This Bigcone was found on the edge of a wash called Holcomb Canyon within the Devil’s Punchbowl Natural Area. The tree is nearly as big around as the record specimen in Baldy Village but just not as tall. I have heard a rumor that the Baldy tree lost some of its crown — so I wonder if the numbers I have for this tree are still correct. Regardless, the tree in the Punchbowl is much more dramatic, being that it is within the Pleasant View Ridge Wilderness and not in the middle of town!
I need to start by clarifying something: in last post about a giant Canyon Oak, I mentioned that I was not a big tree hunter. This post, a few days later, is about a big tree. I think I have become a big tree hunter…
Every day for the better part of the last two weeks, I have been walking through the San Gabriel Mountains getting to know Bigcone Douglas-fir as part of a project with the Angeles National Forest and the California Native Plant Society. I’ll post more about that in the near future. For now, lets look at the white alder (Alnus rhombifolia) I measured in the Pleasant View Ridge Wilderness within the San Gabriel Mountain National Monument while working on that project. Stats on the past record tree can be found HERE.
