It's Deja Vu all over again
- Yogi Berra
Once again I'm asked to provide some perspective on yet another catastrophic situation affecting the North Coast. In 2015, it was the Valley Fire. In 2016, it was the Clayton Fire. This year there are so many fires I'm having difficulty recalling their names...14 at last count.
The cause for these 2017 conflagrations will be apparent once the elements of the fires are assessed. Tornadic winds hitting 50 mph Sunday, October 8, will most likely have started most if not all. Winds of this intensity can ignite fires by impacting electrical infrastructure by breaking lines and causing transformers to explode. The cause of the fires will come out in time. Thick stands of vegetation, the result of mid-20th century land management practices, years of fire suppression, homes built in rural locations in steep terrain, old legacy roads too small to accommodate modern fire-fighting equipment, and exurban development without the necessary resources to address fire prevention. All this leads to almost impossible conditions to arrest a fire being pushed by wind.
I would argue there is no better fire-fighting force in the world than those found in California. What these men and women do is nothing short of extraordinary. But they are faced with an impossible task in the absence of an equally focused program of fire prevention.
What have I learned from Lake County as a result of the Valley and Clayton fires?
The Lake County fires have provided insights that can help with the recovery and reconstruction of the most recent events. Specifically, resources must be secured to assist landowners and communities in better incorporating fire resilience into local rural and suburban planning and projects, to prepare for the eventuality of another fire by creating and maintaining conditions that allow the fire to be controlled before getting out of hand. Admittedly, the recent fires were wind-driven events that became uncontrollable. However, these fires are the exception to the rule. There are hundreds of fires a year in California that are quickly controlled and extinguished. Fire resiliency must incorporate plans and projects that can address less catastrophic conditions, in the hopes of arresting a fire before it becomes a conflagration.
None of this will be easy or inexpensive. But neither is fighting hundreds of thousand acres of wildland fires every year.
Admittedly, the weather conditions responsible for these fires may negate the best plans and efforts. But again, those conditions are the exception to the rule.
For every acre burned this year there are ten more, in the same condition, that didn't, providing next year's opportunity for a conflagration. The road forward to address California's wildland fire threat is long, and full of twists and turns. But as with all long journeys, each begins with the first step.

Art is an expression of creativity, a conveyance of beauty, and for naturalists, it is a way to process, remember and interpret nature.
Many branches of nature art are popular, such as photography, painting and sketching. The UC California Naturalist Regional Rendezvous in October introduced an old but uncommon method for documenting natural objects – cyanotype.
At the CalNat Rendezvous at the Pepperwood Preserve, Santa Rosa artist Jessica Layton taught the cyanotype process to volunteers certified by the UC California Naturalist program, giving them a new tool to use in educating and engaging children and adults in conservation organizations they work with around the state.
The cyanotype process begins by mixing two chemicals - ferric ammonium citrate and potassium ferricyanide – to create the blue photo reactive solution. The chemicals may be purchased at art stores and online by searching for cyanotype solutions.
Once blended, the chemicals are painted on paper or cotton cloth and allowed to dry. Leaves, grasses, seeds, pine cones, flowers, stones – any number of natural objects collected outside may be artfully arranged on the blue background and, if needed, held in place with a pane of glass.
The project is then set out in bright sunlight for 5 to 7 minutes, brought back inside to be washed in clean water and allowed to dry. The areas of the paper or cloth exposed to the sun are a radiant lapis blue; the areas that were shaded by the natural objects appear in silhouette.
“I have come to appreciate art as a way to improve observation skills and deepen an appreciation for nature,” Merenlender said. “We offered this session to our volunteers for them to improve their capacity and become better naturalists.”

I've just begun to work on a smartphone app that I hope will make it easy to assess acreage damaged by the fires, economic value of the forage losses and reseeding requirements and cost assessments. I'll keep you posted on that progress.

Knowing the names of trees is a point of pride for many California Naturalists. So a walk among the diversity of oaks at the Pepperwood Preserve left many feeling humbled.
The three-hour excursion was part of the UC California Naturalist Regional Rendezvous in October at the 3,200-acre nature preserve nestled in the foothills between Napa Valley and Santa Rosa.
Excursion leader Steve Barnhart, academic director emeritus at Pepperwood, said there are 500 oak species in the world; 21 in California. But cohabitating on the rolling hills and valleys of the Golden State, many oaks have produced hybrids that combine characteristics, making identification challenging.
Doctoral candidate Phrahlada Papper, who is studying oak tree genetics, said, “I'm of the mind that you shouldn't ever name an oak.”
Even the tan oak, long thought to be misnamed, is coming under new scrutiny.
“It's not an oak,” Barnhart said. “It has acorns, male and female flowers on the same stalk, but tan oaks are insect pollinated. True oaks are wind pollinated. Tan oaks are closer to chestnuts.”
But Papper raised his hand. “Genetically, it might be an oak,” he said.
Barnhart laughed. “So tan oak is up in the air. That's why it's so much fun to be in science,” he said. “I learned something today.”
In popular culture, oaks are thought to be majestic, towering trees, with wide spreading branches. However, Barnhart said, most California oaks are shrubs, including the leather oak.
Leather oaks grow in serpentine soils and have the ability to produce two types of flowers, one in the spring and another quite different in the fall. Leather oaks are monoecious, they have both male and female flowers on the same plant. On a particular leather oak at Pepperwood, Papper was surprised to find male and female flower parts in one bract and surmised that weather patterns may be responsible.
“California has weird weather and with climate change, it's getting even more weird,” Papper said.
Papper believes tracking phenology, the cyclic and seasonal changes in plants, is an ideal citizen science project for California Naturalists. One such project underway at Pepperwood is led by Wendy Herniman. A University of Edinburgh, Scotland, master's student, Heniman is documenting the phenology of 10 Pepperwood oak trees: 2 blue oaks, 3 coast live oaks, 2 black oaks and 3 Oregon oaks.
“Pepperwood is looking at climate change. It's a designated sentinel site. We're monitoring fog, we have soil probes, and we're collecting all weather and climate information. We can tie that to phenology,” she said. “We're trying to find out if phenophases are changing.”
Understanding the changing phenophases is important, Barnhart said.
“Everything is connected,” he said. “If acorns are produced early, animals species that depend on the food source will be disrupted. You have imbalances in the timing of the natural world. With climate change, what are the effects we'll be seeing?”
