Among Ancient Pines on Mount Linn

As spring transitioned to summer, we traveled deep into the Coast Range to the headwaters of the Bigfoot Trail. Mount Linn—at 8,098 feet, the highest point in California’s Coast Range—rises like an island above a sea of rugged ridges and folded drainages. Here, the Bigfoot Trail begins, and here, we spent our days working to open the path for future hikers—treading, clearing logs, and feeling that familiar rhythm of shared labor in wild places.

Sitka Spruce Decline in California

Where Highway 101 hugs the Pacific Coast in Humboldt County, north through Del Norte County, Sitka spruce (Picea sitchensis) are loosing needles at an alarming rate. This phenomenon, caused by the non-native green spruce aphid (Elatobium abietinum), grew into a noticeable problem in winter 2019-2020. The aphid thrives during winters with warmer than normal temperatures. Last year’s defoliation was especially severe in Oregon and the aphids continues to move south. Sitka spruce decline in California is in its early stages.

All Species Grove

Exploring the remnant old-growth of the Humboldt County Headwaters

In late 1985, a family company in Humboldt County was over taken by a large corporation from Texas. Within a few months, the profit-driven Maxxam Corporation submitted (under the name Pacific Lumber) a furtive timber harvest plan with a rush order to log some of the last, largest swaths of remaining old-growth redwoods in the world. Thankfully, a small group of concerned environmentalists were watching. Leading the guard was Greg King who, along with others, organized and Headwaters Forest Campaign which soon became the largest forest protection civil disobedience demonstration in America’s history.

Western Redcedar in California

From Alaska south to Oregon western redcedar (Thuja plicata) is the signature tree of the Pacific Northwest temperate rainforest. It has mythic importance to native people, as entire civilizations were sustained, in large part, by this species. Natives of the Pacific Northwest regarded the species as a “Long Life Maker” (Stewart 1984) because they used it for canoes, paddles, houses, roofs, clothes, bedding, rope, cooking, and even medicine. Few giant trees were actually felled before the arrival of Europeans because old snags were usable for many years after death. Highly resistant to rot, the snags or parts of live trees would be harvested instead of the entire live tree. After building a dugout canoe from a tree, Lewis and Clark named it “arbor vitae,” Latin for “tree of life” (Arno 2007).

Redwood Experimental Forest

Exploring the Yurok RNA

Many years back I discovered that there were little known biodiversity hotspots that had been described by a handful of ecologists. These places had been designated as Research Natural Areas for the primary purposes of maintaining biological diversity, providing baseline ecological information, and encouraging research and university natural-history education. These places are all relatively pristine and sometimes close to roads in non-wilderness areas.

It was in this way that I first learned about the Redwood Experimental Forest that also contains the Yurok RNA. But I had never visited this place despite the fact it has been on my list since the early 2000s. That all changed in June 2019.
