Sudden Oak death (Phytophthora ramorum) continues its spread across the eastern U.S., following its escape several months ago via contaminated California nursery stock. APHIS is reporting (.pdf) that the presence of this fungus has recently been confirmed in Nassau County, New York. Check that document for a list of nurseries across the country where the pathogen has been found. The Beaufort Gazette is reporting that two infected plants have also been found in South Carolina over the past month, marking the first occurences for that state.
