One of the last remnants of old-growth coast redwood forest and home to some of the world’s largest coast redwoods

In the northernmost reaches of California’s coast redwood range is a lush ancient redwood forest that has captivated visitors for nearly a century: Jedediah Smith Redwoods State Park.

In this complex, multi-layered 10,000-acre rainforest (one of the wettest places in the United States), trees of epic proportions reach for the sky, many of them more than 300 feet tall. Part of Redwood National and State Parks—a UNESCO World Heritage Site that protects 45% of the world’s old-growth redwoods—Jed Smith contains 7% of the remaining old-growth forest, including the Grove of Titans.

In November 2018, Save the Redwoods League partnered with California State Parks, the National Park Service, and Redwood Parks Conservancy to develop an enhanced, ecologically sound visitor experience at Grove of Titans. As of September 2021, the first mile of the renovated Mill Creek Trail has been reopened to the public, providing limited access to the new boardwalk through the Grove of Titans while construction on the Mill Creek Trail continues.

Known for generations by Indigenous people of the area, including the people of the Tolowa Dee-ni’ Nation whose traditional lands encompass Jed Smith, the primeval Grove of Titans remained hidden for thousands of years. Researchers from Humboldt State University came upon its giant trees in 1998 and gave the grove its name. The researchers kept the location secret, but adventure enthusiasts eventually found it and shared the GPS coordinates online in 2011.

With visitors suddenly flocking to the area, hikers would venture off the park’s designated trails in search of the behemoth trees, creating unofficial social trails across the landscape. By 2016, approximately 8,000 square feet (the size of 1 ½ basketball courts) of sensitive understory plants and fungi had been trampled. Tree roots have been exposed, and soil has been heavily compacted, which can cause soil erosion and corresponding runoff that can affect coho salmon and steelhead trout spawning habitat in Mill Creek. The creek flows into the Smith River, known as Nii~-li~ in the Tolowa Dee-ni’ language.

Park managers, conservationists, and researchers had long been concerned about the risks of significant damage to this place and disturbances to wildlife and ecosystems. To address the issues, the first mile of Mill Creek Trail has been renovated, and it features a new, official boardwalk through Grove of Titans. The new elevated walkway is 1,300 feet long and it provides ecologically conscious access to the sensitive area. The remaining 2 miles of the Mill Creek Trail will be renovated and remain closed until early summer 2022.

ADA-accessible parking and restrooms were added along Howland Hill Road. Interpretive exhibits will be installed in fall 2021 to educate visitors about the habitat and trail use. Interpretation was developed in consultation with the Tolowa Dee-ni’ Nation to illuminate the Indigenous history of the area and present-day relationships that Tolowa people have sustained with these lands since time immemorial.

Save the Redwoods League contributed $1,706,746 toward the Grove of Titans project, including a generous dollar-for-dollar challenge grant in 2018 from supporter Josie Merck of Connecticut. The project was also funded by $875,000 from California Natural Resources Agency through Prop 68, the Parks, Environment, and Water Bond Act of 2018; $762,600 in in-kind support from all partners; and $170,000 from Redwood Parks Conservancy donors.

This project fulfills the League’s Centennial Vision objective of ensuring that redwood forests are understood and embraced as critical elements of California’s identity. By strategically upgrading recreational, educational, and interpretive infrastructure in one of the oldest redwood groves in the world, we and our partners are providing a magnificent, ecologically conscious redwoods experience that can inspire a deep sense of connection and stewardship of our iconic forests.

The League’s Redwoods and Climate Change Initiative (RCCI) found that two plots in Jedediah Smith hold 2,090 and 2,160 Mg aboveground carbon per hectare; this forest, among other coast redwood forests, stores more carbon per acre than any other forest type in the world. Old-growth trees in the park, including those in the Grove of Titans, help the forest store about 1,000 tons of carbon per acre aboveground.

As a surviving grove of the ancient redwood forest, the Grove of Titans can provide a model for protecting other ancient stands and accelerating old-growth characteristics in younger redwood forests so they can reach their carbon-storing potential for future generations. Research at the grove is ongoing.
