Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree’s ability to transport water and nutrients. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. As of May 2018, it is now found in 33 states, and the Canadian provinces of Ontario, Quebec, and Manitoba. Since its discovery, EAB has:
- Killed hundreds of millions of ash trees in North America.
- Caused regulatory agencies and the USDA to enforce quarantines and fines to prevent potentially infested ash trees, logs or hardwood firewood from moving out of areas where EAB occurs.
- Cost municipalities, property owners, nursery operators and forest products industries hundreds of millions of dollars.
The Township of Florence is going to wage war against the silent killer of Ash trees in our community. The Emerald Ash Borer is an insect about the size of a dime, but it can kill a 100’ Ash tree in just a few years. Here in New Jersey, it has already claimed millions of Ash trees which once graced entire forests in the Northern part of the state.
Unfortunately, the Ash Borer is in our township and is already killing trees. This page is to inform you that the township will try to combat the infestation with an insecticide that is applied to the roots of Ash trees annually. There is a good chance that the township efforts may only hold off the inevitable and one day we may experience the total loss of our Ash trees in the community. However, we will do what we can to protect the township trees as long as possible.
While the township can only perform preservation techniques on street trees and trees on township property, residents can certainly take on the fight to protect trees on their private property. There are some very informative websites that can help you identify your trees and help you determine if your plants are at risk. The sites also provide some information about treatments for the trees.
