This month, the invasive tree pest emerald ash borer (EAB) was confirmed in the City of Lafayette. This detection is still within a quarantine area established to try and prevent the human-assisted spread of EAB but represents only the third confirmation of EAB anywhere in Colorado outside the City of Boulder, where the pest was first detected in 2013. EAB has also been confirmed in Gunbarrel and Longmont.
