Foresters, landowners, managers, community and conservation groups, land trustees, scientists and policymakers will meet Sept. 13 to 15 in Eureka for the 2016 Coast Redwood Science Symposium.
The symposium, which first convened in Humboldt County in 1996, will feature 70 speakers, 25 poster presentations and three field trips to explore the redwood forests of the North Coast.
“The general public may be interested in attending this conference because it provides a look at the current state of redwood forest management,” said Yana Valachovic, University of California Cooperative Extension forest advisor for Humboldt and Del Norte counties. “This symposium will allow attendees to learn more about how forests are managed today and see the tremendous changes in both private and public land management.”
From Brookings, Ore., to Big Sur, redwoods grow in a variety of habitats and conditions. On the field trips, participants will get to see both conservation and industrial aspects of old growth and timber forests.
A lot can be learned from both private and public land-management strategies and it is critical that the policies and strategies guiding use and management within the redwood region be reviewed and updated based on objective, scientific information, said Valachovic.
“We will discuss changes in milling, manufacturing and energy-producing facilities within the redwood range,” said Valachovic. “Over the last 20 years, there has been a great reduction in these facilities and this comes with a cost because the same infrastructure that supports lumber manufacturing also supports restoration activities.”
In the wake of several catastrophic wildfires this summer, it has been widely publicized that drought, disease and insects have killed more than 66 million trees in California. One place to dispose of dead trees is biomass power plants, which burn low-value forest materials to generate energy for homes and businesses. At the symposium, participants will discuss the impact of recent closures of bioenergy or biomass power plants.
On Wednesday, Sept. 14, three full-day tours are offered:
- North Tour. Redwood National and State Parks and Green Diamond Resource Company will highlight redwood thinning practices. The tour will travel north to the Orick area of Redwood National and State Parks to look at restoration forestry practices designed to enhance structural diversity of younger even-aged forests. The afternoon will be spent walking in the Korbel area, viewing Green Diamond's commercial thinning of third-growth forests and wildlife management strategies in managed landscapes.
- South Tour. The tour with Humboldt Redwood Company looks into conservation planning on industrial timberland. In the historic lumber town of Scotia, participants will tour a mill and visit Humboldt Redwood Company's 40,000 gallon freshwater aquarium. In the afternoon, the tour will hear about active forest management and habitat conservation strategies for the protection of endangered species such as the marbled murrelet, northern spotted owl, and coho, chinook and steelhead salmon.
“This symposium will build on the scientific underpinnings from the first redwood symposium held in Arcata in 1996 and the subsequent 2004 symposium in Rohnert Park, and the 2011 symposium in Santa Cruz,” said Valachovic. “Bringing the symposium back to Humboldt is a great homecoming. Much has changed over the last 20 years.”

It's been over a week since we successfully completed our annual Wreath Workshop at the Buck Mansion in Vacaville. I just wanted to share with you some pictures of the prep days and then the actual workshop. I also wanted to recognize the hard work the Master Gardeners do to make this such a great event. It might entice you to sign up for the workshop in December 2014. I will take RSVP's starting in November.
Traditionally, the workshop is held the first Saturday of December. Participants pay a fee and get greens, a wreath frame, paddle wire, a bow and delicious refreshments for a fee. It's a great way for residents to kick off the holiday season and a lot of fun (work!) for the UCCE Master Gardeners of Solano County.
Oh, and note the wreaths. They are all made from the same exact materials, but each an individual, wonderful creation.

Millions of trees, including tanoaks, coast live oak, California bay laurels, and many other forest species have been killed by sudden oak death in coastal areas of central and northern California, and Oregon. The pathogen, Phytophthora ramorum, was first linked to the massive tree death in the mid-1990s.
David Rizzo, professor in the Department of Plant Pathology at UC Davis, and his research team are studying how the coastal forest ecology is changing since sudden oak death appeared, and why coast redwoods (Sequoia sempervirens) are subsequently so much more susceptible to fire.
It is the presence of the sudden oak death pathogen in forests that poses heavier fire risks for redwoods.
“If redwoods didn’t live in forests affected by the disease, they could withstand fires just fine,” says Margaret Metz, a postdoctoral research scholar working with Rizzo.
According to Rizzo, “The disease likely created more fuel for wildfires as dead tanoak branches fell. The loss of the oaks also would have decreased the amount of shade, drying out the forest and turning it into a tinder box, one not even redwoods could survive.”
A real key, though, is the finding that dead tanoaks, still standing, carry flames high into tree canopies, scorching the crowns of adjacent redwood trees. It’s this crown injury that is believed to have caused so many redwood trees to die in a number of fires that occurred in 2008.
Rizzo, noting that an increase in fire severity is resulting from climate change and global movement of species, says, “There may be all sorts of consequences, among them, dead and dying coast redwoods.”

The Coast Redwood Forests in a Changing California Science Symposium was held June 21-23, 2011, at UC Santa Cruz with just under 300 registrants in attendance. Participants ranged in background from graduate level students to university forestry and natural resource faculty, land managers, conservation groups, public agencies, and land trust members. The symposium was strategically held in Santa Cruz, near the Southern end of the redwood region. Designed to present the state of our knowledge about California’s coast redwood forest ecosystems and sustainable management practices, this symposium was built on earlier redwood science symposia held in Arcata, CA in June, 1996 and in Santa Rosa, CA in March, 2004. The symposium was jointly organized by the forestry programs at UC Berkeley, Cal Poly San Luis Obispo, and Humboldt State University, and partially supported by a grant designed to encourage research and outreach collaboration between the University of California and the California State University systems.
Attendees participated in a day long field trip and two days filled with opening sessions, concurrent presentations on research and management case studies, and a poster session. An ongoing theme of the symposium was the need for action and collaboration from all directions, including public and private land owners and managers, as well as academics and policy makers.
During the opening panel, local historian Sandy Lydon gave a synopsis of the settlement of the area and how the redwoods will always have a special history in the region. He recounted stories from his boyhood about roaming through the forests. He reminded the audience to take time from their schedules to spend time in the forests, and to urge their children to play outside to develop an appreciation for the outdoors and cultivate their imaginations.
Ruskin Hartley, Executive Director and Secretary of Save the Redwoods League, questioned what it means to save the redwoods today and argued that buying and placing land in public ownership is not enough. He believes the next 100 years will focus on restoring forests collaboratively between public and private entities. Hartley called on the audience to set “audacious goals and take collaborative actions.” He maintained that nature does not develop boundaries and that in moving forward, we should focus on a shared set of goals so that public and private land can progress simultaneously. In a time of climate change, the lines we draw on maps become increasingly irrelevant, instead we need a new paradigm to “think about building resilience and adaptability to climate change into the system to benefit both public and private owners.”
Ron Jarvis, Home Depot’s Vice President of Sustainability talked candidly about the role of environmental sustainability practices and policies as part of the home improvement retailer’s business model. He noted that when he began in the sustainability department he undertook a two year long project to understand where every sliver of wood from over 9,000 products originated to ensure sustainable wood practices. Recently, Home Depot sent a memo to their current vendors asking them to supply Home Depot with the names of their “green products.” The green product inventory exceeded over 10,000 products, yet when Jarvis’s team investigated further they deemed only about 2,000 to be worthy of the green standard. Jarvis showed that products today, because of packaging or brand names, may seem green, but the consumer must really investigate what they are buying. Jarvis hopes that in his position he can take some of that burden off of the consumer so that the majority of products that reach Home Depot shelves have already passed the test.
During the concluding ceremony on the future of research in the redwood region, the panel, as well as audience members, recognized the need for more communication among those working with redwoods to spread research findings and best practices. Inspired by the concurrent presentations and research presented at the poster session, participants were looking for a way to stay in touch and collaborate - as Hartley noted in the opening session is crucial for the next steps of redwood growth and preservation. 100% of participants who completed the follow up survey are excited to network and collaborate at similar events, meaning there are opportunities to further enhance the redwood and green movements.
Proceedings of the symposium are anticipated to be available in early Fall 2011 to document the various studies in the literature.
