N.Y. RED OAK SHOWS SIGNS OF CALIFORNIA MALADY Date: 040801

From: http://www.dailynews.com/


HAS TREE DISEASE SPREAD? By Patrick Healy, New York Times, July 30, 2004



Oyster Bay Cove, N.Y. - A botanical mystery is playing out at the


Tiffany Creek Nature Preserve, here amid rolling hills and sprawling


Long Island estates. A single red oak tree at the preserve has tested


positive for sudden oak death syndrome, a disease that ravaged forests


in California, and scientists are trying to figure out whether the


infection is a dire beginning or a false alarm.




Scientists with the U.S. Forest Service and the Department of


Agriculture are equally baffled and worried. Sudden oak death syndrome


has killed tens of thousands of trees and cost governments and plant


nurseries millions of dollars, but until now, it has only been found


in trees in Northern California and southern Oregon.




A knotty red oak tree standing in the preserve first tested positive


for the disease last month, and scientists said Wednesday that they


were running a battery of secondary DNA tests on tree samples to


determine whether the tree truly carries the debilitating bug. Tests


on trees in Pennsylvania and New Hampshire have yielded false positive


results before, said Kerry Britton, a pathologist for the Forest


Service.




"I'm still hoarding the hopes that it's not really there," Britton


said. "If it is a positive, they'll have to declare a quarantine zone


around the area and declare an eradication effort. They'll have to cut


down that tree and trees around there. It's up to the state to decide


how drastically."




Environmental officials throughout the Midwest and the East Coast


have feared an outbreak of sudden oak death syndrome ever since trees


in California began dying from the disease in the mid-1990s.




A fungus-like pathogen called Phytophthora ramorum hops from plant to


plant by riding rivulets of windblown rain, scientists said. It can


lay dormant in trees for years, and then kill them within weeks. Oaks


are not the only trees affected. The disease has killed more than a


dozen species of trees on the West Coast, and has prompted quarantines


of potentially infected plants from California.




Steven Swain, a researcher at the University of California at


Berkeley, who has studied the disease, said early tests on East Coast


oaks have shown them to be more vulnerable to the disease than trees


in the West.




"If this gets loose on the East Coast, it could cause quite a bit of


damage," Swain said.




No other trees, ferns or plants in the Tiffany Creek preserve have


tested positive for the disease.




Scientists took 60 other samples from the suspect red oak and tested


any tree within 20 acres that showed a passing sign of illness,


officials with the inspection service said. They expect the test


results next week.
