ALBANY - After years of trying to slow a voracious Chinese beetle that is decimating ash trees, state environmental officials are waving the white flag: The Department of Environmental Conservation dropped a logging quarantine, and said it might be time to cut healthy trees still uninfested. In a brief notice posted online Wednesday, the DEC repealed logging restrictions that had failed to contain the spread of the emerald ash borer (EAB) by limiting shipments of ash. The state created the quarantine in 2015 to slow the insect, which is a shiny green beetle about the size of a penny. The borer likely will ultimately bring about the end of the state's 700 million ash trees - down from earlier estimates of 900 million ash trees before the beetles' arrival - and forever change an industry that uses ash to produce bats for major league baseball.
