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.

Community Forestry Strategic Plan

The Hennepin County Community Forestry Strategic Plan (PDF) defines goals and objectives that the county’s forestry program will pursue from 2020 to 2025 to protect the county’s tree canopy and increase the benefits that trees provide. 

The plan includes more than 50 strategies to achieve the following goals: 

  • Plant, diversify, and maintain trees throughout Hennepin County
  • Increase the resiliency of Hennepin County’s community forest
  • Build organizational capacity to support, value, and maintain trees
  • Educate and engage residents to become stewards of the community forest

Together, the strategies outlined in this plan will build stronger internal and external partnerships, get more people involved in caring for trees, and increase awareness of the values of trees. They will also establish effective forestry policies, better prepare communities for current and future threats to trees, ensure trees are used to reduce disparities and respond to climate change, and capture success stories that inspire further action. Pursuing all these strategies will create a healthier and more resilient community forest and ensure more equitable opportunities for communities to experience the benefits that trees provide.

Developing the plan

The strategic plan was developed using a participatory planning process that incorporated feedback from both internal and external partners.

Through a series of workshops, county staff developed a vision for the future of the forestry program, recognized potential barriers, identified strategies, and drafted goals.

A meeting with external partners was held to gather feedback on the draft goals and strategies. The meeting had 40 participants representing forestry and public works programs in Hennepin County cities, past recipients of Heathy Tree Canopy grants, state and regional governmental agencies involved in natural resource management, the University of Minnesota, and local nonprofits involved in green space management and education. Key insights from those meetings were incorporated into the plan.

Implementing the plan

Hennepin County foresters are beginning to implement strategies identified in the plan as they carry out their 2021 work plan. The plan will be submitted to the Hennepin County Board of Commissioners for formal adoption along with the updated Natural Resources Strategic Plan later this year.

Hennepin County foresters are interested in discussing partnership opportunities that help meet the goals of the strategic plan or hearing any additional ideas you have. Connect with them by emailing trees@hennepin.us

Community forestry progress report: 2021

Creating a community forestry program in the Environment and Energy Department was part of the county’s expanded role in natural resource conservation. The forestry program focuses on protecting the county’s tree canopy to increase the benefits that trees provide. Trees improve air quality by absorbing fine particulate matter and other pollutants and protect water by slowing down and infiltrating stormwater runoff. They also provide shade, reduce the urban heat island effect, lower stress, and increase property values.

Aspects of the county’s forestry program include growing healthy trees, partnering in large-scale planting events, managing threats to the tree canopy, raising awareness about tree pests and disease, educating the public on the benefits of trees and supporting partners through the Healthy Tree Canopy Grant program. 

Hennepin County foresters were busy throughout 2021. Some highlights of the work that was accomplished include:

  • Planted 570 gravel bed trees and shrubs throughout the county.
  • Held a tree sale where residents purchased over 2,000 seedlings.
  • The city of St. Anthony and Tree Trust Youth Build crews utilized a free application created by Hennepin County to collect tree inventory information. Data points were collected on 832 trees.
  • Monitored 685 trees by measuring width and determining growth and survival rates.
  • Continued to update inventory of ash trees on county property. As of December 2021, there are 1,180 existing ash trees within the right-of-way along county roads.
  • Planted 41 gravel bed trees along Portland Avenue in Minneapolis and Richfield.
  • Conducted an inventory of diseased trees within rights-of-way along county roads and flagged 83 trees for removal during the 2021-2022 winter.

Tree identification guides

Use these resources to help with tree identification:

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 a number of resources to learn about emerald ash borer and options for managing ash trees:

Saving your mature ash trees

A healthy, mature ash tree may be worth saving, and treatment with an insecticide is an option to preserve ash trees of high value.

Watch "Protecting ash trees from the threat of emerald ash borer" (YouTube) to learn how to determine if your tree is worth saving and see how treatment works.

Healthy Tree Canopy grants awarded in 2021

In September 2021, the county awarded 21 Healthy Tree Canopy grants totaling about $404,000. Grant projects will take place in nine cities, on 10 affordable housing properties, at four schools, and through five nonprofit organizations, including congregations and neighborhood associations. More than 1,000 trees will be planted through the grant projects.

The grants will:

  • Fund the collection of data through tree inventories, which is critical to increasing and diversifying the tree canopy and starting to respond to emerald ash borer.
  • Address the impacts of tree pests and pathogens by improving city forestry capacity and treating or replacing and replanting ash trees that are threatened by emerald ash borer. Grantees are required to plant at least one replacement tree for every ash tree removed.
  • Educate residents on the benefits of trees and engage them in tree planting efforts.
  • Improve livability and reduce disparities by planting trees in neighborhoods throughout the county experiencing disproportionate amounts of economic, environmental, and health inequities. Most of the grants awarded are within medium and high priority planting areas on the county’s tree planting prioritization map.
  • Protect people and increase the county’s resilience to climate change — important goals in the county’s Climate Action Plan — by increasing the benefits that trees provide. These benefits include capturing carbon, reducing air pollution, and taking up stormwater, and providing shade to counteract the urban heat island effect.

Grants awarded to cities

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, 1,000 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 good 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.
