Article - Sudden Oak Death in NY??
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. * * * Copyright (c) 2004 Los Angeles Daily News -- Mike LaMana, MS Heartwood Consulting Services, LLC Toms River, NJ www.HeartwoodConsulting.net |
