Urban forests

Urban and Community Forestry Program

Urban forests are the trees in the cities and neighborhoods where we live. The urban forest includes trees along streets, in parks and natural areas, and in your own backyard. Urban forests provide many important environmental, social, and economic benefits and services too.

Urban forestry is the care and management of these trees in cities. Many cities have an urban forestry or other tree care program that manages trees along city streets and in parks.

In 2021, the ODF Urban and Community Forestry Program celebrated 30 years of service. The program has assisted communities with developing, improving, and expanding their urban forestry programs. Contact the program to learn how your city can become more involved in urban & community forestry activities.

Gov. Kotek proclaims April 2024 as Oregon Arbor Month

Oregon Governor Tina Kotek has proclaimed April 2024 to be Oregon Arbor Month throughout the state.

Arbor Month is a traditional time for communities to celebrate trees and their vital role in making our communities healthier and more livable. Arbor Month is an outgrowth of Arbor Day, which began in Nebraska in 1872 as a tree-planting campaign. The day dedicated to trees and tree planting soon spread nationwide, and expanded in many states to a week-long celebration.

In Oregon, with more and more tree-related activities happening around the state, it was decided a few years ago to expand the event to encompass the whole month of April. This has made it easier for communities east of the Cascades to participate in tree plantings after the ground has thawed and danger of hard freezes has passed. Read the full proclamation.

​​​​​​The Tree City USA program is a national program that provides the framework for community forestry management for cities and towns across America.

Communities achieve Tree City USA status by meeting four core standards of sound urban forestry management:

  • Maintaining a tree board or department
  • Having a community tree ordinance
  • Spending at least $2 per capita on urban forestry
  • Celebrating Arbor Day

Participating communities have demonstrated a commitment to caring for and managing their public trees. In Oregon, nearly 70 communities participate in the Tree City USA program.

If your community is interested in becoming a Tree City USA, please contact an Urban and Community Assistance Forester, view the storymap about celebrating Oregon's Tree City USA communities, or visit the Arbor Day Foundation website​.

Tree Campus USA

The Arbor Day Foundation also recognizes college and university campuses committed to their green space through the Tree Campus USA program. Tree Campus USA schools:

  • Effectively manage their campus trees
  • Develop a connection with their community beyond campus borders to foster healthy, urban forests
  • Strive to engage their student population with campus and community forestry efforts

​​​Tree City USA communities

April was proclaimed as Oregon Arbor Month for the first time in 2021.​ To mark the occasion, the Oregon Department of Forestry asked the state's 69 Tree City USA communities to send us a photo capturing the city's Tree City USA spirit. These same cities were asked the question, "What does earning Tree City USA recognition mean to your city?" With this information, we created what we believe is an inspiring and engaging story, combining images, text, and an interactive Oregon map. The storymap made its debut April 15 in the middle of Arbor Month.

​​​Between 2019 and 2023, three dozen Oregon communities have planted a total of 54 Hiroshima peace trees. These are saplings grown from the seeds of trees that survived the atom bombing of Hiroshima in August 1945 and sent by volunteers with Green Legacy Hiroshima to cities around the world as ambassadors of peace. The plantings were a combined effort by the Oregon Department of Forestry and the non-profit organizations Oregon Community Trees and the Medford-based One Sunny Day Initiatives. Oregon is believed to have the highest density of Hiroshima peace trees outside of Japan.

Appreciating city trees

​​In Oregon, we set aside the month of April to honor trees. Click here for information about Oregon Arbor Month or contact your local Urban and Community Assistance Forester.  In addition, click here ​to discover 14 pandemic-safe ways to celebrate Oregon Arbor month.

Arbor Day is America's national tree holiday. It's a day other states set aside to plant ceremonial trees, educate children about the importance of trees and honor the important role trees play in our daily lives. National Arbor Day is celebrated on the last Friday in April, but Oregon observes tree related activates all month to fit best tree planting times statewide. 

For more information on Arbor Day or to plan a celebration, visit the Arbor Day Foundation.

​​A Tree Board, sometimes called “Tree Advisory Committee” or “Tree Commission,” is a group of citizen volunteers charged by ordinance with developing, guiding, or administering a community tree management program. A Tree Board advises and assists city professionals by:

  • Raising public awareness and public education about the value of trees
  • Serving as a technical advisor on tree related issue
  • Helping work on city tree care codes or a management plan
  • Advocating for trees
  • Promote Heritage Tree programs
  • Organizing tree planning projects and Arbor Day ceremonies

Cities with Tree City USA status already have a Tree Board of some sort.

If your city is not already a Tree City USA, consider starting a Tree Board in your town by contacting your mayor or city manager. Also consider attending "Tree Board University​​​," a free, online series of courses to help you learn more about serving in a citizen advisory role in your city.​​

​​Late spring in Oregon with its long hours of daylight and warmer weather is a great time of the year to share your love of trees with your community. Although the people who care for urban trees are busy watering, pruning, and performing other day-to-day maintenance tasks, with trees leafed out and some still in flower, the weeks before summer are great times of the year even during our pandemic to celebrate and educate others about the many benefits trees provide.

Adding a few fun education and outreach activities into your summer work plan helps raise awareness of trees and your program at a time when a lot of residents have more time on their hands because of COVID-19. You can reach an even larger audience by joining forces with other programs and non-profits in your area.

Here are some good examples that residents of your community can engage in from home or alone at a safe physical distance from others:

Tree tours – Se​​lf-guided or online

  • Solicit suggestions from community members to locate favorite trees in your town, then: 
    • Create an online tour to showcase trees by taking photos and posting descriptions.
    • Create and print a brochure with a map for a self-guided city tree tour. Partner with a food delivery service to include one with deliveries in neighborhoods near the tour route.

Tree stories

  • Collect stories about historic or prominent community trees and partner with the local newspaper to publish a “tree of the month" article.
  • Research the history of a prominent local tree and consider nominating them as a heritage tree for your city or even with the state-level Heritage Tree program

Team up with your community's parks or recreation department

  • Offer an online tree identification webinar.
  • Host a Zoom meeting about tree art – discuss how people can go find twigs, leaves, and branches in their yards or nearby (without damaging trees) and create interesting collages or other artwork.

Partner with local or regional arborists

  • Hold online workshops explaining tree care or maintenance, proper pruning or tree watering, etc.
  • Hold a photo contest that highlights park trees in your community. The contest winner might receive a tree, planted on their behalf in their favorite park next spring. (Hint: Tree City USA Arbor Day grants can pay for trees planted for Arbor Day events.)
  • Work with a local bookstore to hold a “poe-tree" contest; display selected poems in large type in the store window or in City Hall. (Hint: Haiku poems are short and easy to fit on a single sheet.)

This list may help stir up some ideas about how you can involve your community in the joy and benefits provided by trees, while raising the visibility of your city's urban forestry program and the importance of caring for the community forest.​
