The city of Quincy is hosting a second presentation on the emerald ash borer at 6 p.m. Tuesday in the council chambers at City Hall, as the "tree killer" continues to spread across the state.
Scott Schirmer, of the Illinois Department of Agriculture, will offer information on the emerald ash borer, the danger it poses, the effects it will have on ash trees, treatment options and disposal of diseased trees.
Jeff Palmer, a certified arborist with tree injection technology company Arborjet, discussed treatment options last month.
A 2000 survey showed 1,042 ash trees on city-owned property in Quincy, representing 9 percent of the city's trees.
The Department of Agriculture announced Monday that it added Henry and Knox counties to the emerald ash borer quarantine. The 39-county quarantine covers 40 percent of the state. It prohibits the movement of ash trees and products from outside the area to slow the spread of the beetle.
Since first detected in Detroit, Mich., the emerald ash borer has killed more than 25 million ash trees.
