In memory of Dr. Steven J. Seybold:

This issue commemorates the life and career of Dr. Steven J. Seybold who passed suddenly and tragically on November 15, 2019. Steve was a prolific research entomologist, a kind and genuinely considerate colleague, and a dear friend to many at PSW.

Susan Frankel recently coordinated a donation to the Western Forest Insect Work Conference's (WFIWC) Memorial Scholarship in Steve’s name on behalf of PSW. This donation will serve to support a student award that several of Steve’s former graduate students have won.

In addition, two recent publications have been dedicated to Steve's memory, including a special issue in The Canadian Entomologist and Invasive Species in Forests and Rangelands of the United States: A Comprehensive Science Synthesis for the United States Forest Sector.

Steve's passion for science and his work are well known by all who knew him. His contributions to the fields of forest entomology and chemical ecology will remain influential for years, and his legacy lives on through the many graduate students and colleagues he mentored and/or collaborated with during his career.

Steve's passing has left a sizeable hole in PSW and the forest entomology community. He is sorely missed.

Special issue on managing bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) with semiochemicals: honouring the remarkable career of Dr. Steven J. Seybold. Fettig, Christopher J.; Graves, Andrew D.; Huber, Dezene P.W. The Canadian Entomologist. 153: 1-3.

Featured publication:

Increasing frequency and extent of high-severity wildfires pose a significant threat to California’s ecosystems. This is evident in both tree- and shrub-dominated landscapes, where novel, human-driven fire regimes may result in large-scale alteration of terrestrial ecosystems and decline in the services they provide. Based on these trends and a broader consideration of sustainability, there is a growing need for a well-supported, science-based approach to postfire management.

This report presents a framework to guide the development of postfire restoration on national forests in California. The framework is founded on a set of guiding principles and a five-step process that leads to the development of a restoration portfolio that can inform project planning and monitoring. We discuss the application of this approach to California’s forest, chaparral, and sagebrush-steppe ecosystems. The restoration framework can inform future postfire management, monitoring, and research in California’s diverse ecosystems.
