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

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.

Type of grants available

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

See the Healthy Tree Canopy grants flyer (PDF) to learn more about the difference between the grant types.

Cities

Two types of grants are offered:

  • Step 1: For cities with no tree inventory or an incomplete tree inventory. Grants are only to complete tree inventories. Grants of $1,000 to $5,000 are available, and a 25 percent match is required.
  • Step 2: For cities that have a completed tree inventory and a city forester that is at least a 0.3 FTE and ISA certified. Grants are to, implement tree plantings, maintain newly planted trees, replace ash trees, conduct outreach, develop gravel-bed nurseries and develop tree management plans. Grants of $5,000 to $50,000 are available, and a one-to-one match is required.

See the healthy tree canopy grant guidelines for cities (PDF) for more information.

Affordable housing

Grants are for tree removals and planting replacement trees on affordable housing properties.

Grants are available to new and existing affordable housing properties. Eligible applicants include owners and managers of existing affordable multifamily housing, developers of new affordable multifamily housing, and affordable housing land trusts.

Grants of a minimum of $1,000 up to a maximum of $20,000 are available. A 25% match of the granted amount is required.

See the healthy tree canopy grant guidelines for affordable housing properties (PDF) for more information.

Schools and non-profit organizations

Grants are for tree plantings on school or community properties, tree-related education, and Arbor Day celebrations.

Eligible applications include charter, private, and public schools in Hennepin County. Eligible applicants include administrators, teachers, principals, and facility managers of existing schools. Non-profit 501(c)(3) groups are also eligible to apply.

See the healthy tree canopy grant guidelines for schools and non-profit organizations (PDF) for more information.

Additional application 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.

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 dustin.ellis@hennepin.us or 612-348-2259.

Education and volunteer opportunities

Hennepin County offers training classes and volunteer opportunities for residents interested in tree care.  

Tree steward class

Tree steward classes cover the basics of tree biology, tree planting, watering, pruning, and tree health through a combination of classroom instruction and hands-on, outdoor field experience. Classes are offered in partnership with the University of Minnesota and host cities. 

After completing the class, volunteers have opportunities to help plant and care for trees with the county and partnering organizations.

Classes are open to the public, and no experience is needed. The University of Minnesota provides the necessary tools and safety equipment. Participants should dress appropriately for being outside.

Upcoming classes

There are no classes scheduled at this time. 

Get notified of future classes

Tree steward class dates and locations are being planned for 2018. If you would like to be notified when the schedule and registration is available for future tree steward classes, contact Shane DeGroy at shane.degroy@hennepin.us or 612-543-3697.

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 they should be taking steps now to determine if they have ash trees on their property and how they are going to manage them.

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

Visit our ash trees and emerald ash borer website to learn more about the threat of emerald ash borer and options for managing ash trees.
