Pacific Silver Fir in California

Part 2: Marble Mountain Wilderness

Read Part 1

From Conifers of the Pacific Slope

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.

Diamond Lake – English Peak Revisited

Marble Mountain Wilderness

Hike 14 from Conifer Country

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.

Klamath Mountain Peat Bog

Isinglass Lake

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.

Isinglass Lake is surrounded by an accumulation of peat, know as a peat bog.

Heterotrophic Plants

Parasites and Mycotrophs of the Klamath Mountains

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!
