A Multi-stakeholder Approach to Moving Beyond Tree Mortality in the Sierra Nevada

The US Forest Service has estimated that 102 million trees have died in California since 2010. This die off event has been attributed to the combined effects of historical land management practices, fire suppression, insect outbreaks, and climate-related stressors. This tree mortality event represents the largest and most significant ecological disturbance in California in centuries, if not longer. Both scientists and managers recognize the need to rethink our approach to forest management in the face of a changing climate and increasingly frequent, uncharacteristically large wildfires, while budgets and staffing capacity continue to decrease. Addressing the uncertainly in managing under climate change with fewer financial resources will require multiple partners and stakeholders—including federal and state agencies, local governments, and non-governmental organizations—to work together to identify common goals and paths moving forward. The USDA California Climate Hub and USFS Region 5 convened a symposium on drought and tree mortality in July 2017. With nearly 170 attendees across a wide range of sectors, the event provided a meaningful opportunity for reflection, analysis, and consideration of next steps. Among the outcomes of this symposium was the identification of areas in which our capacity for individual and synergistic action is stronger, and those in which it is lacking that will thus require additional attention and effort. From this symposium, which included a series of smaller, stakeholder and partner working groups, we collectively identified research and information needs, possible policy adjustments, future management actions, and funding needs and opportunities. Here, we present these findings and suggest approaches for addressing the current tree mortality event based on the shared interests of multiple, diverse stakeholder groups.
