It’s summertime in California and that means two things are certain. It will be hot, and fires will scorch our wildlands. I was reminded of this as I was preparing to leave campus a few weeks ago when I noticed the sky was filling with a faint orange glow. In the mountains west of Davis, the Wragg Fire was beginning to take off and was sending huge plumes of smoke into the valley.
We learned later that UC Davis’ Stebbins Cold Canyon Reserve near Lake Berryessa was right in the path of the fire, which burned more than 8,000 acres. Almost all of the 576-acre reserve, which is used by our faculty and students, falls within the burn perimeter. The reserve is now closed to the public until damage can be assessed and restoration work carried out.
Reserve director Jeffrey Clary noted that in the aftermath of the fire there will be many science stories to tell: research opportunities stemming from the burn, potential restoration initiatives that can involve the community, a citizen science project based at the site that will need to be rebuilt. “We are happy to work with all of you to make sure we remain engaged with campus and the community during this period,” he said.
Wildfires can also exact a tragic human toll when they injure people, claim lives, and destroy homes. According to Cal Fire, at one point the Wragg Fire threatened 136 structures, including the homes of some CA&ES staff and faculty. Although a couple of outbuildings were destroyed, only one home was damaged and none was destroyed in this fire. People fleeing other wildfires in the state haven’t been as fortunate. The huge Rocky Fire in the Coast Range destroyed 43 homes and 53 outbuildings.
In recent decades more and more homes have been built in remote areas, increasing the human risks and costs associated with wildland fire. Fighting the disastrous 2013 Rim fire near Yosemite cost more than $127 million. But the real costs of a wildland fire are always much greater, typically including not just suppression but damaged structures, private timber stand losses, revegetation and slope stabilization, utility repairs, road and sign damage, and business interruptions.
While wildfires are a natural part of California’s history, their frequency, size, and duration have increasingly been influenced by the presence of humans and changes in our climate. Environmental science and policy professor Mark Schwartz, who is also director of the John Muir Institute of the Environment, has studied the effect of climate change on wildfires, as well as where and when plant communities are predicted to exhibit stress as a consequence of unusual climatic conditions (including wildfire).
He and colleagues recently published an article in the journal, Ecosphere, reporting that wildfires in the Sierra Nevada are increasingly burning high-elevation forests. Historically, Sierra Nevada forest fires rarely burned above the 8,000-foot elevation. But that’s changed in recent decades, with more fires burning at higher elevations. The phenomenon is likely being driven by climate change, forest-management practices, and other factors.
“The increase of higher-elevation forest fires is yet another harbinger of climate change,” Schwartz said in a UC Davis news release about the study. “With California currently in the midst of a four-year drought, low snowpack in the mountains and related forest stress are further increasing the chances of large, destructive fires that move high into the Sierra.”
The study may influence how forest managers respond in restoring a forest after a fire. Wildfire is a fact of life in California, and research like this helps provide a foundation for the development of sound policies for natural resources management. Drought and climate change will keep wildfire and its consequences on our radar for the foreseeable future.
