Do you support prioritizing fast-growing trees over long-lived species to restore your local canopy?

City officials and researchers from the University of Minnesota planted 25 Innova hybrid poplar trees near 59th Avenue West in Duluth. This project aims to replace native trees that were lost to an emerald ash borer infestation.

Why it matters

The Innova hybrid was chosen for its rapid growth rate, which allows the trees to reach full maturity much faster than traditional species. This project helps the city restore its canopy while testing the viability of a patented hybrid in local conditions.

The city and the Natural Resources Research Institute planted 25 Innova trees along a 15-foot wide boulevard. The Innova is the first patented and trademarked hybrid poplar in the United States, utilizing roots that expand quickly to facilitate rapid growth.

The players

University of Minnesota

This is a public land-grant research university that collaborates with local governments on agricultural and environmental initiatives.

Natural Resources Research Institute

This organization is a research arm that focuses on developing sustainable solutions for natural resource management.

The details

The project serves as a test for replacing damaged canopy following extensive damage from the emerald ash borer. Researchers plan to monitor the site for several years to determine the effectiveness of the hybrid species before potentially introducing maples or oaks.

A report regarding the new tree planting was published on October 14, 2026.

The Big Picture

The Duluth planting follows the pattern of urban reforestation efforts necessitated by the emerald ash borer infestation. This discovery shifts the discipline by utilizing a patented hybrid poplar to replace native trees that were lost to the pest.

The introduction of these fast-growing hybrid trees could lead to quicker restoration of urban shade and improved local air quality. Residents living near the 59th Avenue West boulevard will see the immediate replacement of trees that were previously removed due to pest damage.

The takeaway

Using specialized hybrid trees can accelerate the recovery of city greenery after invasive species cause significant damage to local landscapes. Residents should observe the growth rates of these new trees as the city evaluates them for future reforestation projects.
