The Emerald Ash Borer (EAB) insect has negatively impacted the health of many Ash trees in the Midwest United States. This non-native insect has caused many Ash trees to gradually die. Ash trees have a connective tissue-like system inside them that transports water to the roots and leaves. EAB larvae feed on the area in the tree just below the bark, damaging this system and causing the tree to become brittle and eventually die. The Ash tree limbs may become so brittle, which can cause them to unexpectedly fall. Falling branches and tree debris may cause damage to you, your car, or your home. 

If an Ash tree loses 30% of its canopy, it’s best to have it removed and / or replaced with another

tree. Many municipalities and homeowners have decided forgo the insecticide treatments of the Ash trees and instead replace them with new species.

Keep in mind that it's advisable to employ professionals for the removal of any dead or dying trees.


Some of the best tree options to replace Ash trees are:

  • Oak Trees - Swamp white oak (Quercus bicolor) and bur oak (Quercus macrocarpa) are suitable replacements for ash trees. These oaks are native to Minnesota, tolerant of wet soils, and provide excellent shade and wildlife habitat.

  • Maple Trees - Sugar maple (Acer saccharum), red maple (Acer rubrum), and silver maple (Acer saccharinum) are all native to the midwest US and can thrive in ash tree habitats. They offer attractive fall color and provide shade.

  • Linden (Tilia americana): This fast-growing tree has a broad canopy and heart-shaped leaves. It prefers full sun to partial shade and medium soil moisture.

  • Black Spruce (Picea mariana) and Tamarack (Larix laricina) mix: These conifers can thrive in wet areas and provide shade along streams.

  • Quaking Aspen (Populus tremuloides) This tree is found in a wide range in the upper Midwest. In wind, the leaves make a sound when they hit each other. This is how the tree gained it's name “quaking” aspen. It will grow to 40 to 50 feet at maturity. 

  • Red Maple (Acer rubrum): This fast-growing tree is known for its brilliant fall foliage and can tolerate a range of soil conditions. It’s a good option for areas with full sun to partial shade.

  • Accolade Elm (Ulmus ‘Accolade’): This disease-resistant elm variety can tolerate a range of soil conditions and provides a notable presence in any landscape.

Considerations

  • When selecting replacement trees, consider factors such as soil type, moisture levels, sunlight, and wind exposure.

  • Native trees are generally a better choice, as they are adapted to local conditions and provide habitat for native wildlife.

  • Non-native trees can still be a good option if they are well-suited to your specific site and provide benefits such as shade, beauty, or wildlife habitat.


It’s best to consult with a certified arborist or forester to determine the best replacement tree species for your specific location and needs. They can assess the site conditions and recommend the most suitable alternatives to ash trees.
