The state placed a quarantine on all eight counties of Western New York in an effort to slow the spread of the invasive emerald ash borer.
The state this week expanded the quarantine zones to cover all or part of 43 counties.
As of last summer, the restricted area locally covered all of Niagara and Orleans counties and portions of Erie, Chautauqua, Cattaraugus, Genesee and Wyoming counties. All eight counties were covered by the quarantine as recently as 2014.
Under the state's restrictions, ash firewood, logs, branches and nursery stock may not be taken out of the quarantine zone without a compliance agreement or permit from the Department of Agriculture and Markets.
Most trees infested by the ash borer beetle die within 2 to 4 years. Treatment of infested trees does not guarantee they will survive. The first confirmed ash borer infestation in the state was in Cattaraugus County in 2009, according to the DEC.
