Village confirms emerald ash borer found in EL

The presence of the Emerald Ash Borer (EAB) was identified and confirmed in the village of Elkhart Lake on village-owned property along State 67 south of the fire station Friday, April 21.

Elkhart Lake now joins a growing list of Wisconsin communities where the insect has been detected.

Sheboygan County, which includes Elkhart Lake, has been under an EAB quarantine for the past few years, since the borer was found in the southern part of the county in July 2014.

Residents should be aware that it is illegal to move firewood out of the EAB quarantined area, as it is the primary means for the EAB to spread. It is best to keep firewood onsite.

Homeowners who would like more information on EAB and the quarantine area, or are interested in determining whether they have an ash tree on their property and information on how they protect it from EAB, should visit the state of Wisconsin’s official website,, and click on the link for homeowners. Additional information on the EAB is also available at Village Hall.

In preparation for the EAB, Elkhart Lake has not planted ash trees on village parkways or in village parks since 2007. The village’s Tree Commission has been proactive in identifying the ash trees located in parkways and parks. There are less than 50 ash trees in these areas.

The Tree Commission has completed treatment of the eight ash trees located in Village Square Park. These treated trees will not have to be retreated for at least two years and there is a possibility that the treatment may prove to last for an additional year.

The rest of the village’s parkway ash trees will be removed proactively based on the health of the tree. Any ash tree in parks or parkway that becomes a safety hazard will be removed.

The village will continue to diversify the trees that are planted throughout the village. The village has begun “shadow” planting trees in the park and will continue this planting procedure as much as possible over the next few years.

The emerald ash borer is a major threat to Wisconsin’s trees. Once present in an area, the EAB kills all untreated ash trees within a few years. Even young, healthy ash trees are killed within 3-5 years of infestation.

Whenever making choices for EAB prevention and treatment, homeowners and commercial industries should review the latest research and decision making tools available. The village will strive to continue diversification of the trees along the parkways.

There is no solution to stop the spread of EAB and no way in which to eradicate the EAB. Citizens concerned with the condition of an ash tree are encouraged to contact a tree service they are familiar with or an ISA-certified arborist. A listing of certified arborists may be found on

Property owners should take these measures:

Keep a close watch on ash trees for signs of possible EAB infestation: Thinning in the canopy, D-shaped holes in the bark, new branches sprouting low on the trunk, cracked bark, and woodpeckers pulling at the bark to get to insect larvae beneath it.

Consider preventive treatments for property within 15 miles of a known infestation. Whether to treat depends on several factors: the age of the trees, the size of the trees, and the number of trees. Treatment costs vary depending on size of the tree and whether you do the treatments yourself or hire a professional.

Consider planting different species of trees that are not susceptible to EAB.

Homeowners should visit or contact the Wisconsin Department of Agriculture, Trade, and Consumer Protection at 1-800-462-2803 if they would like more information on EAB and the quarantine area, or are interested in determining whether they have an ash tree on their property and information on how they protect it from EAB.
