Emerald Ash Borer (EAB)

Emerald Ash Borer was confirmed in New York 17 June 2009.

Most trees die within 2 to 4 years of becoming infested. The emerald ash borer is responsible for the destruction of over 50 million ash trees in the U.S. since its discovery in Michigan.

Adult beetles leave distinctive D-shaped exit holes in the outer bark of the branches and the trunk. Adults are roughly 3/8 to 5/8 inch long with metallic green wing covers and a coppery red or purple abdomen.

In New York, if you suspect EAB in your ash trees, call the DEC's EAB and Firewood hotline at (866) 640-0652. More info: emeraldashborer.info and DEC EAB.

Asian Clam

The Asian clam, Corbicula fluminea, is a small bivalve native to southern Asia, the eastern Mediterranean, and Australia. They are usually less than 1.5 inches in size, with a light green / light brown shell and distinctive concentric ridges.

Asian clams were found off Lake Avenue Beach in Lake George Village in August 2010, with initial concentrations of up to 600 clams per square meter across approximately 2.5 acres.

Asian / Eurasian Milfoil

Eurasian milfoil reproduces through fragmentation. It spreads rapidly and displaces beneficial native plant life, makes swimming difficult, and can devalue waterfront property. Under optimum conditions, milfoil may grow up to an inch per day.

Milfoil most likely arrived as a "stowaway" fragment attached to a boat or trailer. Milfoil can live out of water for many hours if it remains moist.
