Trees and forestry

Trees and forests provide many benefits, including improving our air and water, making ourselves and our communities healthier, reducing the urban heat island effect, providing wildlife habitat, saving energy and increasing property values.

The tree canopy in Hennepin County faces a number of threats, including development, insects and diseases, climate extremes, and poor installation and maintenance.

The county has programs and resources available to help protect and enhance our tree canopy.

Grants to improve the tree canopy

About the healthy tree canopy grants

Hennepin County has grants available to cities, affordable housing properties, schools, and non-profit organizations to enhance the county’s tree canopy.

The goals of the program are to combat threats to trees from invasive insects and disease by funding tree planting, educate the public on tree care and the importance of trees, and increase the diversity and resiliency of the tree canopy.

Types of grants available

Different types of grants are available to cities, affordable housing properties, and schools and non-profit organizations.

Helpful grant resources

The following resources will be helpful in completing your grant application.

Tree planting priority areas map

The county’s tree planting priorities map factors in both environmental and demographic data. The map uses land cover data and disparity data such as income, housing, and health to understand areas that have lower tree canopy and higher need.

Grant selection will be based, in part, on a comparison of the project locations with the identified priority planting areas.

Recommended tree list

Use the county's recommended tree list (XLSX) when developing a planting plan.

The list includes a list of species and notes about their suitability for planting in various locations. A do-not-plant list is also included.

Grants for cities

In February 2019, the county awarded 27 grants totaling more than $250,000. The grants will not only invest in the county's tree canopy, but also the health and economic vitality of communities.

Tree planting and reforestation

Hennepin County plants and maintains trees on sites throughout the county in partnership with cities, libraries, community organization and schools. Planting projects include along county roadways, at county libraries and facilities, at schools and parks, and in natural areas and conservation easements.

Gravel-bed nursery

Most of the trees the county plants come from the county's gravel-bed nursery, located at the Hennepin County Adult Corrections Facility in Plymouth. The gravel-bed nursery gives the county access to hardy, diverse and cost-effective trees for use on county projects and properties.

Every spring, 1,500 young saplings of a variety of species are purchased from commercial nurseries and planted in the gravel-bed. The trees grow and develop a good root structure throughout the summer, and are ready to be transplanted in the fall.

Compared to conventional nursery trees, the gravel-bed nursery gives the county access to a wider diversity of tree species, produces trees that have a higher survival rate, and allows the county to plant trees in a more cost-effective manner. The gravel-bed nursery is also helping the county proactively replace ash trees that will ultimately be infested with the emerald ash borer.

Planting projects

Trees from the gravel-bed nursery are transplanted to a variety of county projects and properties.

Examples of planting projects that the county has or is working on include:

  • Arbor Day plantings at various locations
  • Community locations: including along the Midtown Greenway, at schools and in parks
  • Hennepin County facilities and libraries
  • Restoration projects in natural areas and conservation easements
  • Transportation and transit corridors

Assistance available

If you are looking for assistance with a planting project or are interested in installing a gravel-bed nursery, contact Dustin Ellis at or 612-348-2259.

Emerald ash borer

Emerald ash borer, an invasive tree pest that attacks and kills ash trees, is the biggest current threat to our tree canopy. There are over 1 million ash trees in Hennepin County, and 100 percent of them are threatened by the emerald ash borer. Most residents live within 15 miles of an infested ash tree, which means you should be taking steps now to determine if you have ash trees on your property and how you are going to manage them.

Options for managing ash trees from the threat of emerald ash borer

Hennepin County has the following resources to learn about emerald ash borer and options for managing ash trees:
