Brian Nearing is reporting in the Times Union a fatal oak tree disease has resurfaced in Glenville, Schenectady County, three years after state conservation officials cut down dozens of oak trees to stem an outbreak. Officials from the state Department of Environmental Conservation last week moved to quarantine two areas in Glenville to contain the potential spread of oak wilt disease. DEC officials could not immediately say how many trees are infected. Emergency orders will prohibit the removal of oak or firewood of any species from the protective zone. Oak wilt is caused by a fungus, and has killed thousands of trees nationwide. It attacks all species of oak, but it can kill red oaks in only a few weeks. There is no known treatment to save a tree once it is infected. Infected trees lose all their leaves, beginning in July or August. Photos of suspected infected trees can be sent to foresthealth [at] dec [dot] ny [dot] gov or call 1-866-640-0652 for help. Read the full story in the Times Union.
