What should I do if the city marks my tree for removal?
As Emerald Ash Borer (EAB) continues to impact trees across Minnesota and the Twin Cities metro area, some residents are returning home from work to find their ash tree marked indicating it must be removed—often within as few as 30 days. What may be more surprising is that cities are not only “tagging” trees growing along the public right-of-way, but also private trees located anywhere on the property—including back yards.
Ash tree marked for removal
Can a city require a homeowner to remove a privately owned tree?
In a word: yes. Most municipalities have ordinances that allow the city to inspect and require the removal of trees that may pose a safety risk, such as threatening a road way or sidewalk, or to reduce the spread of disease. Any type of dead or dying tree poses a safety risk and may be tagged for removal because it is a hazard. In Minnesota, there are three types of trees that present widespread risks related to a highly contagious deadly pest or disease.
In Minnesota, which tree pests or diseases may require a tree to be removed?
The most common serious threats to tree health in Minnesota are Emerald Ash Borer in ash trees, Dutch elm disease in American Elms, and Oak wilt in red or white oaks. There are effective treatments to prevent these pests and diseases from spreading to other trees or killing your tree. However, because these conditions are so deadly and spread so quickly, they require prompt attention.
- Oak wilt is a fast-moving, deadly fungal disease that impacts red and white oaks. It spreads through insect carriers and tree root systems. An infected tree must be treated or removed to prevent neighboring trees from being infected.
- Dutch elm disease (DED) is a fungal disease carried by elm bark beetles and can be spread through tree roots. If caught early, it is possible to cut out an infected area of a tree and treat it.
- Emerald ash borer (EAB) is an invasive pest that kills unprotected ash trees. Treatments are effective in preventing EAB, but time is running out. Homeowners should plan to have their ash trees treated this summer, or removed this winter.
What to do if your tree has been “tagged” for Emerald Ash Borer
If your tree has been marked, contact your local forestry or parks department for more information. Some cities use different colors of spray paint to indicate which of the three health concerns were found. Most often there will be other information left behind, such as a doorknob sign with instructions for you to follow.
Why is removing EAB infested ash trees so urgent this year?
When trees are newly infested with EAB, there are no visible signs. However, after they have been infected for about 3-5 years, they often decline very quickly and die. Ash trees become brittle very quickly after they die which makes them a safety hazard. Right now, there are tens of thousands of untreated ash trees being impacted at the same time. Managing such a high volume of tree removals is a daunting task, particularly when cities are also racing to slow EAB’s spread.
What are some cities doing to ensure EAB-infested ash trees are removed on time?
If your ash is marked for removal, there may be a deadline for removing your tree. If the tree isn’t removed by that date, the city may issue a fine. Some cities will hire a contractor to remove the tree, charging the property owner for the removal costs, along with an additional administrative fee.
How can I avoid having my ash tree marked for removal?
Minnesota tree experts recommend treating ash trees this summer. After that, it may be too late to save them. This is because ash trees must be healthy enough for the treatment to be effective. If the insect damage has advanced too far, the tree simply can’t recover. Because the borers feed under the tree’s bark, there may be extensive damage long before it is outwardly visible.
What should I do if I do not want to treat my ash tree, or an arborist has told me my tree isn’t a good candidate for treatment?
If the tree is showing signs of dying, plan to remove it soon. If the tree is still reasonably sound, plan to remove it this winter. That way you can enjoy one last summer of shade, and enjoy the benefits of winter removals, including reducing the impact to other parts of the landscape when it’s frozen.
