CT Invasive Species
The Emerald Ash Borer, an invasive Asian Beetle, was found in CT in 2012. Originally found in the US in 2002, this destructive insect is spreading across the country and is responsible for the death and decline of ash tree species.
If you have ash trees on your property, please be alert for any signs of this insect. Ash Trees make up about 4% of the trees in CT and up to 20% of the urban trees in some communities. Ash Tree Identification
