Insect endangers Ky. ash trees - State - Kentucky.com:
By Andy Mead - firstname.lastname@example.org An insect called the emerald ash borer has been found in two Kentucky counties, which means trouble for the state's hundreds of millions of ash trees.
Officials estimate that the beetle has killed tens of millions of ash trees in Michigan, and tens of millions more in 10 other states and two Canadian provinces.
The most common ash tree in Kentucky is the white ash. The state Division of Forestry estimates that there are 131 million white ashes in Kentucky. There are an estimated 92 million green ash trees.
A 2005 survey in Lexington found that 11 percent of the city's street trees are ashes."
