Sarah Navarro

Forest Pathologist | Department of Forestry, Oregon, USA 

Presentation Title: Utilizing multiple landscape level detection and modelling tools for management of Phytophthora ramorum in Oregon

Meet the Presenter:

Sarah Navarro is the Regional Sudden Oak Death Pathologist for the United States Forest Service. She provides technical assistance to the Pacific Northwest Region on Sudden Oak Death and other invasive Phytophthoras. This is a brand-new position in the Region, and she hopes to continue to slow the spread of Sudden Oak Death.

Before joining the Forest Service in June of this year, Sarah worked for the State of Oregon for the last six years at the statewide Forest Pathologist for the Department of Forestry and a Plant Health Specialist for the Department of Agriculture. Sarah has a Master of Science in Botany and Plant Pathology from Oregon State University and a Bachelor’s in Biochemistry and Molecular Biology / Fungal Biology and Ecology from the University of California at Davis.

In spare spare time Sarah enjoys mushroom hunting, mountain biking, and skiing.

Sudden Oak Death (SOD), caused by Phytophthora ramorum, is lethal to tanoak (Notholithocarpus densiflorus) and threatens this species throughout its range in Oregon. In July 2001, the disease was discovered in coastal southwest Oregon forests. Since 2001, an interagency team has attempted to eradicate and slow the spread of disease through a program of early detection, survey and monitoring, and destruction of infected and nearby host plants.

Survey, detection, and monitoring efforts compose of ground, aerial and stream bait surveys. Eradication treatments, totalling approximately 2550 ha, eliminated disease from most infested sites, but the disease continued to spread slowly, mostly in a northward direction.

In order to improve early detection of outlier infestations, we integrated new landscape level methods for detection, incorporated new disease models to determine high risk areas, and utilized new participatory disease modelling tools to engage stakeholders and focus funding and policy decisions.
