Minnesota Partnerships & Discounted Emerald Ash Borer Treatments

As of January 2023, Rainbow Treecare has partnered with over 35 cities throughout the Twin Cities to treat public trees in parks and along boulevards. City partnerships are integral to Rainbow’s commitment to preserving our urban ecosystem.

These partnerships also include a citywide discount to private property owners. If you are a property owner in one of our partner cities, you will receive a discount on ash tree protection.  While we can’t manage the entire urban forest, we can all help by protecting One Tree at a Time.

How do our city partnerships benefit residents?

EAB has caused wide-reaching and fast-spreading damage to our urban forest. Considering that ash trees once made up 15-20% of the tree population in the Twin Cities, losing them is having a devastating effect on the region’s tree canopy. 

There are numerous benefits to a municipality implementing a citywide EAB Management Program:

  • Having a greater number of trees under protection against EAB can slow the rate at which EAB infests and kills untreated trees nearby 
  • Slowing the death rate allows more time to fund the transition away from ash trees and replace them with other tree species 
  • Reducing the number of dead ash trees that need to be removed at the same time lowers safety hazards as resources remain available for the timely removal of dead trees
  • As a property owner utilizing a city partnership, you will receive a property visit and consultation with an ISA Certified Arborist or certified tree inspector
  • Property owners living in partner cities receive discounted ash tree protection 

The entire community benefits from our city partnerships as the mature tree canopy is preserved through city and homeowner participation.

Additional frequently asked questions about city partnerships

The emerald ash borer (EAB) is an invasive beetle from Asia. EAB was first discovered in the United States in 2002 near Detroit, Michigan, and has since spread throughout the country. It was found in St. Paul in 2009, and every county in the Twin Cities has infestations. EAB has quickly become one of urban forest history’s most destructive and costly forest insects.

EAB larvae feed on the inner bark of ash trees, which disrupts the tree‘s ability to transport water and nutrients. EAB populations can grow exponentially yearly because the beetle has few natural predators, and our ash trees have limited natural defenses. Once an ash tree is heavily infested, it has almost zero chance of survival. Proactive treatment is the only proven and reliable method of saving an ash tree.

With an estimated 1 in 5 trees in the Twin Cities metro area being an ash tree, losing this many of them is comparable to a natural disaster with a significant environmental and economic impact. When EAB is not managed, annual ash tree deaths can quickly overwhelm the resources required to remove dead and dying trees. This results in a large number of hazardous dead trees, along with a significant financial burden to both property owners and cities.

The first step is an inspection of your ash tree by one of our tree experts. We will evaluate your tree to determine if treatment is still an option. If your ash tree is healthy, we recommend treating your tree as soon as possible. Our licensed technicians perform EAB treatments by injecting product into the tree’s trunk above the soil line. The product is then taken up naturally by the tree’s vascular system, the same way nutrients and water are moved throughout a tree. Treatment needs to be repeated every two years to provide ongoing protection. Read more about our emerald ash borer protection service.

The cost of treating your tree is based on the size of the tree. Tree size is determined by measuring the DBH (diameter of the tree at breast height, or 4.5 feet off the ground). Treatments typically range from $70 to $200 per tree in the metro area and are recommended every two years. Protection costs significantly less than removal and replacement, and you retain the value of a mature tree on your property.

The cost of removing a tree is based on several variables. A small tree with no obstacles nearby may cost hundred dollars to remove, while a large, hard-to-access tree near a structure can cost thousands. Unfortunately, trees in decline are more challenging and costly to remove. Stump removal is also an additional cost.

If you remove a tree, replanting is recommended. Depending on the size of the replacement tree and whether you hire a professional to plant it, tree replacement can cost between $50 and $400.
