Researchers in California have announced that they have found coast redwood and Douglas fir trees infected with P. ramorum. These infections have been limited to leaves (needles), small branches and sprouts. We have placed these plant parts under regulation (7 CFR 301.92) and provided notification of this action via a SPRO letter.
