Trees and Community Forestry

Emerald Ash Borer (EAB) is an invasive insect pest that aggressively spreads and kills green ash trees. EAB was confirmed in Fridley in 2019, and since then outbreaks have been confirmed throughout the city. The larvae of EAB tunnel under tree bark, which interrupts the flow of water through the tree. Once symptoms are present, the ash tree typically dies within one to three years. If you have an ash tree on your property, act now to treat or remove it before the tree becomes a safety hazard. The City is offering an income-qualified ash tree removal and replacement program for a limited time, please see information about the program within the "Income-Qualified Ash Tree Removal Program" section.

Ash Tree ID

Ash trees are one of the most common shade trees in Fridley. An estimated 30% of the City's publicly owned trees are ash with thousands more located on private property. To tell if you have an ash tree, look for:

• Diamond- patterned bark on mature trees
• Leaves and branches that are opposite each other
• Leaves comprised of small leaflets

What to Do About EAB?

If you have an ash tree in your yard, assume that it will become infested with EAB and die without intervention. Due to the ubiquity of ash trees throughout the city, the impact of EAB in Fridley will be devastating without resident help. If you have an ash tree, you may choose to:

1. Treat your ash tree.
2. Remove (and replace) your ash tree.

Due to the shade, air quality, and water quality benefits provided by mature trees, the City recommends treating ash trees that are:

• Over 10 inches diameter
• In a good location
• Not exhibiting advanced EAB symptoms (>30% canopy loss)

Although trees must be treated every 2-3 years, it is usually more cost efficient to treat the tree long-term than remove it.

Treating Your Ash Tree

You can protect your tree against EAB infestation using chemical treatment. Chemical treatment must be reapplied every two to three years. Do not wait until the tree is exhibiting symptoms of EAB to start treatment as the damage may be irreparable and the tree too far gone. Treat the tree using a systemic chemical injected by a Fridley-licensed tree company. Some chemicals used to treat EAB can be harmful to beneficial insects such as pollinators if applied improperly. Systemic injections are the most effective form of treatment and are the least likely to adversely impact pollinators. Avoid using treatments that are applied as soil drenches, which can leach into water or drift to pollinator habitat. The City will be contracting with Birch Tree Care to treat high-quality ash trees in City-owned parks and right-of-ways between 2024-2026. As part of this program, Birch Tree Care will be extending a bulk treatment price to Fridley residents of $6 per inch based on the trees diameter at breast height.

The City of Fridley received funding through the DNR ReLEAF grant program to improve our community forest by supporting tree planting and ash tree removal on properties owned by income-qualified residents. Grant funds can be used to:

1. Remove and replace ash trees impacted by emerald ash borer
2. Plant new trees

Up to three trees can be removed and/or planted on a property. Grant funds are limited and available on a first come-first serve basis. Participants are responsible for keeping their trees alive by following the maintenance schedule(PDF, 4MB). Project spots for tree removals for the fall are currently full. Additional funding may be available for the spring. To be put on the waitlist for the spring, please email rachel.workin@fridleymn.gov for an application. Backyard trees will be reviewed on a case-by-case access for removal as funding allows.
