2019. Jared LeBoldus (OSU) planting seedlings. Field trial to examine genetic variation in resistance to Sudden Oak Death (Phytophthora ramorum) in tanoak, Douglas-fir, coast redwood, and Port-Orford-cedar. Established near Brookings, Oregon.

More about the project from Richard Sniezko:
A field trial was established in southern Oregon, near Brookings, in March 2019 to examine genetic variation in resistance to Phytophthora ramorum (pathogen causing Sudden Oak Death) in tanoak, as well as susceptibility of conifers Douglas-fir, coast redwood, and Port-Orford-cedar. The trial was a joint effort between USFS (Dorena Genetic Resource Center, FHP), OSU, and ODF.
900 tanoak (Notholithocarpus densiflorus) seedling ‘families’ from 55 Oregon parent trees (and bulked lots) were planted in a field trial to assess genetic resistance to Phytophthora ramorum (pathogen causing sudden oak death, SOD), and to correlate with results of seedling inoculation testing done at Oregon State University. Douglas-fir (Pseudotsuga menziesii), coast redwood (Sequoia sempervirens), and Port-Orford-cedar (Chamaecyparis lawsoniana) seedlings were also planted to test conifer susceptibility.
