| Emerald Ash Borer Detection Tree Program FAQ |
- What is a detection tree?
- An EAB detection tree is an ash tree with a section of the bark removed, or “girdled,” from a tree trunk. Research has shown that the EAB adults are more attracted to a stressed tree. It has proven to be a very useful tool in finding the early stages of an EAB infestation, which helped locate previously undetected populations of the beetle during the 2004, 2005 & 2006 EAB detection tree programs.
- Where will the detection trees be located?
- The EAB ash detection trees will be strategically located in every county at varying
densities in Michigan’s Upper Peninsula, as well as Emmet and Cheboygan Counties of Michigan’s Lower Peninsula. These trees are located within the road right-of way and set by MDA staff. Additional surveying is also being done by other agencies and entities, such as the Michigan Technological University which is setting detection trees in public and private parks and forest lands.
- What will happen to the detection trees?
- The trees were identified and girdled during the fall and early winter of 2006, and will be in place until the following fall. Beginning in mid-September 2007, the detection trees will be cut down, the bark peeled to look for EAB larva, and properly disposed of in accordance with the state quarantine regarding regulated ash materials. Any outlying EAB infestations identified through the detection tree program will be evaluated into the state’s EAB management strategy.
