Chad Finn, a berry breeder with the USDA’s Agricultural Research Service at Oregon State University, said freeze damage was spotty. Berry test plots in Corvallis and at OSU’s North Willamette Research and Extension Center in Aurora survived the cold. Fields in the Forest Grove area west of Portland and nearer the Columbia River Gorge, where cold air pools, sustained damage, Finn said.
