Emerald Ash Borer
Emerald Ash Borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle discovered in southeastern Michigan near Detroit in the summer of 2002. In 2013, it was identified in Boulder, and it was recently found near the Town of Berthoud in Larimer County. The borers are metallic green and up to one half inch long; adult beetles nibble on ash foliage but cause little damage to the leaves themselves. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Infested trees gradually die over a period of approximately two to four years.
The City of Greeley first developed its EAB management plan in 2014. By educating the public on how to identify and avoid bringing the beetle to the area (and to manage the beetle when it is found inside city limits), we help protect the city’s urban forest from the potential dangers caused by the pest.
At this time, the Emerald Ash Borer has not been identified in the City of Greeley. The City of Greeley Forestry Program pro-actively collects samples from local ash trees on a regular basis to look for the beetle’s presence. By educating our community, we also encourage residents to keep watch for the beetle’s presence.
With EAB, it is not a matter of if the beetle will appear in Greeley; it is a matter of when.
