Climate change, drought and wildfire: The application of climate-informed and user-driven responses for postfire reforestation in California

The Climate Adaptation Research Seminar Series is a webinar series that will share the most current adaptation research from its members on climate-related topics. The seminars will give participants a taste of the wide breadth of research conducted by research members on the UC Davis campus. 

 

Climate change, drought and wildfire: The application of climate-informed and user-driven responses for postfire reforestation in California

Presented by Dr. Steven Ostoja

The effects of climate change are already apparent across many forested ecosystems in California. In some cases, these have been magnified by antecedent factors associated with land management decisions past such as fire elimination and more recent anthropogenic related dynamics such as population development. There has been a sharp increase in climate-linked stressors and disturbances in the last decade, replete with water stress, forest pest outbreaks and of course wildfire. A hallmark example of this was the tree mortality event coincident with the historic 2012-2016 California mega drought and bark beetle outbreak that killed ~130M trees across the state.  The epicenter of impact was in the Southern Sierra Nevada, chiefly the Sierra and Sequoia National Forests.  And perhaps not surprising to some, two of the largest fire incidents in 2020 occurred on those management units respectively.  The Creek fire burned nearly 380,000 ac. mostly on the SNF and the Sequoia complex fire (SQF) burned just over 174,000 ac primarily on the Sequoia National Forest and Monument.  The former fire was the largest single incident event in the history of California.  As part of this seminar I will summarize lessons learned in the four years since the last epic drought with special attention to forested ecosystems and the services they provide the states nearly 40 million residents.  Additionally, I will present various management resources and tools that have been developed to respond in a post disturbance events like large high severity wildfires.  Finally, I will present a conceptual framework outlining a comprehensive, all lands and climate-informed approach for revegetation and reforestation statewide.  Afterall, if climate change, including more intense and longer lasting droughts and associated disturbances like wildfire are expected to increase in frequency and scale in the years to come our preparedness and post disturbance response portfolio should be commensurate.
