Dead and dying ash tree removal in Minneapolis
In Minneapolis, most dead-tree removals are ash killed by emerald ash borer. Dead ash dry out and become brittle quickly, which makes them dangerous to leave and harder to remove safely over time. If the Minneapolis Park and Recreation Board has condemned a private tree, the notice sets a deadline for removal.

How to tell if your ash is infested
Emerald ash borer larvae feed under the bark and cut off the tree's water and nutrient flow. From the ground, look for thinning at the top of the crown, sprouts along the trunk, vertical bark splits, D-shaped exit holes about an eighth of an inch across, and heavy woodpecker activity that strips bark in light patches ("blonding"). By the time these show, damage is usually advanced.
Why dead ash are riskier than other dead trees
Ash killed by EAB tend to become brittle faster than many other dead trees. Limbs snap unpredictably, and climbers can't trust them for rigging. That's why tree companies often use bucket trucks or cranes for dead ash, and why waiting usually makes removal slower and more expensive. Taking down a declining ash before it's fully dead is often the safer and cheaper choice.
From first symptoms to a brittle dead ash
- 1
Thinning at the top
The upper crown thins first as larvae feed under the bark.
- 2
Woodpeckers and bark splits
Woodpeckers strip bark to reach larvae, leaving pale patches; bark cracks over feeding galleries.
- 3
Sprouts and heavy dieback
Shoots appear along the trunk while the crown dies back. Treatment usually won't save the tree at this point.
- 4
Dead and drying
Within a few years of death, the wood becomes brittle and limbs drop without warning.
Dead elms and oaks: the other dead trees in Minneapolis
Not every dead tree here is an ash. American elms still die of Dutch elm disease, which killed much of the city's canopy in the 1970s, and oaks die of oak wilt. Both diseases spread to nearby trees, so a dead elm or oak should be identified before it's removed.
Diseased elm and oak wood is handled differently from ordinary firewood, and in Minneapolis the Park Board can require removal of diseased private trees. Removing oaks in winter avoids the spring and early-summer window when oak wilt spreads through fresh wounds.
Park Board condemnation, winter timing and wood
The Minneapolis Park and Recreation Board inspects private trees for EAB and Dutch elm disease and can mark them for removal. A condemnation notice gives the owner a deadline, and if the owner doesn't act, the board can arrange removal and assess the cost. Winter is the preferred removal season here: frozen ground supports equipment, and crews have more availability. Keep ash wood local, since moving firewood is how EAB spreads.
Removing an ash on a typical Minneapolis lot
- Most backyard ash are reached from the alley, which lets a lift or crane work without crossing the lawn.
- Garages, fences and overhead lines along the alley decide how the tree is taken down; dead ash are usually cut from a lift rather than climbed.
- Frozen ground in winter protects lawns and lets heavier equipment in.
- Ask for the stump to be ground in the same visit or scheduled after the thaw.
Protecting the ash next door
If one ash on the block is dying, the beetles are already in the area. Healthy ash nearby, yours or a neighbor's, can still be protected with treatment if most of the canopy is intact. Treatment has to be repeated every few years and works best before decline starts.
For ash that are already thinning badly, planning removal while the wood is still sound is safer and usually cheaper than waiting.
Minneapolis dead tree questions
Is it dangerous to leave a dead ash tree standing in Minneapolis?
Yes, if it can reach anything. Dead ash become brittle quickly and drop limbs unpredictably. Removal also becomes riskier for the crew the longer it stands.
What happens if MPRB condemns my tree?
You'll get a notice with a removal deadline. If the tree isn't removed by then, the Park Board can have it removed and bill or assess the cost to the property.
Can I keep the ash wood for firewood?
Burn it locally. Don't transport ash firewood out of the area; moving firewood spreads emerald ash borer.
