Key Takeaways
- Emerald ash borer has killed tens of millions of ash trees across Michigan.
- Dead ash trees become increasingly brittle and unpredictable as decay progresses.
- A tree can retain some leaves while already having significant structural damage.
- Removal decisions depend on tree condition, location, targets, access, and weather exposure.
- Ash logs and firewood should be handled according to current Michigan guidance.
Ash trees were once common throughout Michigan neighborhoods, farms, woodlots, and streets. Emerald ash borer changed that landscape. The Michigan Department of Agriculture and Rural Development reports that the invasive beetle has killed tens of millions of ash trees in Michigan since it was first discovered in 2002.
Across Southwest Michigan, many property owners are now dealing with dead or declining ash trees near homes, barns, driveways, roads, trails, and fences. These trees are not simply a landscape concern. Their branches and trunks can become brittle, making them difficult and dangerous to leave standing or remove.
How Emerald Ash Borer Damages Ash
Emerald ash borer larvae feed beneath the bark and disrupt the tissues that transport nutrients through the tree. As the infestation progresses, the canopy thins and branches begin to die.
Visible signs may include –
- D-shaped exit holes
- winding galleries beneath the bark
- vertical bark splits
- epicormic shoots
- woodpecker activity
- loose bark, and
- dieback in the upper crown
Decline does not always happen evenly. One ash may die quickly while a neighboring tree remains partially green. A tree retaining leaves is not necessarily structurally sound, particularly when it has large dead limbs, bark loss, or trunk defects.
Why Dead Ash Trees Become Dangerous
Living trees can respond to certain injuries by compartmentalizing damage and producing new wood. Dead trees lose that ability. As the wood dries, branches become brittle, bark separates, and decay organisms weaken the trunk and root system.
A dead ash may develop falling-limb hazards, trunk fractures, root decay, and an increased likelihood of failure during wind, snow, ice, or heavy rain.
The location of the tree is critical. A dead ash in a remote woodland area may pose little immediate risk if it has no target. The same tree beside a house, driveway, barn, public road, or play area may require prompt removal.
What Is a Target?
A target is anything that could be damaged if a tree or branch fails. Homes, garages, barns, vehicles, utility lines, roads, trails, fences, and livestock shelters can all be targets. Risk also depends on how often the area is used. A tree above a rarely visited woodland path may present less immediate risk than one above a driveway used several times a day.
A professional tree service firm in Southwest Michigan can perform assessment considers the tree’s size, defects, lean, decay, root condition, fall zone, and the likelihood that people or property will be exposed.
Signs That Removal May Be Necessary
Property owners should arrange an assessment when an ash has large dead limbs, a noticeable lean, trunk cracks, loose bark, fungal growth near the base, soil movement, hanging branches, or storm damage. A tree that has stood through one winter is not necessarily safe. Decay continues, and the next storm may expose weaknesses that were not visible from the ground. Dead ash trees may also become more difficult to remove over time. Brittle sections can break unexpectedly, and decay can make traditional climbing or rigging methods more complex.
Treatment or Removal?
Treatment may be appropriate for an ash that is still alive, structurally sound, and showing limited decline. Michigan State University materials explain that treatment works best when started before significant canopy thinning or dieback.
A tree may be a treatment candidate if it has strong structure, limited crown loss, substantial landscape value, and a location where it can be monitored safely. Treatment cannot restore a dead ash. It also cannot repair a trunk that has extensive decay or a root system that no longer provides adequate stability. An arborist should evaluate the tree before a property owner invests in treatment.
Planning Safe Removal
1. Site Assessment
Before removal begins, the crew evaluates the tree and surrounding area. They plan where the tree will be dismantled and how sections will be safely lowered.
2. Protecting the Property
The removal plan should protect nearby structures, lawns, roads, and remaining trees. Proper planning helps reduce the risk of accidental property damage.
3. Specialized Equipment
Dead ash removal may require ropes, loaders, cranes, or specialized cutting techniques. The equipment used depends on the tree’s size, condition, and location.
4. Establishing a Safe Work Zone
The crew may create an exclusion zone to keep people away from falling branches and equipment. Traffic and driveway access may also need to be controlled.
5. Identifying Underground Hazards
Homeowners should inform the tree company about septic systems, irrigation, buried utilities, fences, and drainage lines. Knowing these locations helps prevent damage during removal.
6. Avoid DIY Removal
Homeowners should not attempt to remove dead ash trees near structures or utility lines. Brittle, weakened wood can break unexpectedly and create serious safety hazards.
Handling Ash Wood
Ash logs and branches may be suitable for firewood, chipping, or other uses, but transporting them can spread emerald ash borer and other pests. Michigan regulates the movement of certain firewood and ash materials. Before moving ash wood, verify current requirements for the property’s location and the intended destination. Processing material on-site or using a local disposal option may be preferable.
Replanting After Removal
Once a dead ash is removed, property owners often want to replace it. Replanting can restore shade and wildlife value, but the new tree should match the available space and soil conditions. Consider mature height, canopy width, drainage, sun exposure, utilities, building proximity, and maintenance needs. Diversifying the landscape with several suitable species can reduce the risk associated with relying heavily on one type of tree. The planting area may need stump grinding, soil improvement, and compaction relief before a replacement tree is installed.

Brawner’s Tree Service uses specialized equipment and controlled techniques to help reduce the risk of property damage. We also provide cleanup, wood handling, and stump removal after the tree is removed. Timely professional removal can help protect your property, family, and surrounding areas.
Frequently Asked Questions About Dead Ash Trees in Southwest Michigan
Can a dead ash remain in the woods?
Sometimes. If it has no target and does not interfere with roads or trails, leaving it may provide habitat. Large or unstable trees should still be assessed.
How long can a dead ash stand?
There is no dependable timeline. Decay, diameter, exposure, weather, and root condition all affect failure risk.
Can I burn ash from my property?
Possibly, but movement restrictions may apply. Check current Michigan rules before transporting firewood.
Should every ash tree be removed?
No. Some living ash trees may be treated or monitored. Dead or hazardous trees require a separate removal assessment.
Summary Checklist: Dead Ash Tree Removal

| Replacement tree is planned | Mature size and site conditions | Select a diverse, site-appropriate species |
Final Advice
Emerald ash borer has made dead ash trees a widespread removal concern across Southwest Michigan. A tree may remain upright long after it has lost significant structural strength, and waiting for failure can expose homes, vehicles, and people to unnecessary risk.
Brawner’s Tree Service can inspect declining or dead ash trees, evaluate nearby targets, and recommend treatment, monitoring, removal, disposal, and replacement options. Addressing the tree before a storm turns it into an emergency is usually the safer approach.
