(Portland, OR) – Portland is a city of trees. There are over 238,000 street trees alone, and another 1.2 million trees in our parks and natural areas. The rest of the urban tree canopy, which covers over 29% of the city, are trees on private property, including neighborhood yards and gardens.

Most homeowners and businesses depend on professional arborists to help them maintain the trees in front of and on their property.

To increase understanding and compliance with city rules and regulations regarding tree care removal and planting, the City is providing training for companies that care for trees in Portland.  Training will cover:

               •             Title 11 rules and regulations for public and privately-owned trees

               •             How to fill out a tree permit

               •             Tips for ensuring your permit is approved

               •             Tree mitigation plans and tree selection 

               •             Working with customers to explain the tree code

Upon completing the workshop and providing City and State license numbers, participating businesses will be added to the  “Portland Tree Care Providers List” on the Portland Parks & Recreation website.  In addition, certified Arborists will be eligible to receive two International Society of Arboriculture (ISA) continuing education units for attending this workshop.  Please bring your ISA certification number with you to receive credits.

The City of Portland is committed to preserving, protecting and enhancing our urban forest. The work done by green-industry professionals is crucial to achieving these goals. Local arborists, landscapers and others, are encouraged to take advantage of this free workshop and learn more about the City’s rules and regulations. Please call Portland Parks & Recreation Urban Forestry at 503.823.TREE or email for more information.

Planting Cherry Trees Creates Living Memorial to Japan’s Tsunami and Earthquake

Akebono Cherry March 24 2008

March 11 marks the fourth anniversary of the massive earthquake and accompanying tsunami that struck eastern Japan in 2011. The earthquake was the fourth strongest ever recorded anywhere. Together with an accompanying tsunami, it claimed more than 15,000 lives, with over 2,000 people still missing and presumed dead.  It was the costliest catastrophe to hit Japan since World War II. To commemorate it, the Japanese, like so many other cultures memorializing tragedies, are planting trees. But they are doing so in a unique way.

Over the next decade, some 17,000 pink-flowering cherry trees will be planted to mark the line where the tsunami unleashed by the 9.0 earthquake reached inland, in some cases six to 12 miles from the ocean. When fully planted, this living memorial will stretch for 105 miles. Everything seaward of where the trees will stand was engulfed by the roiling wall of seawater, which claimed more lives than the shaking ground. Proponents hope the memorial will help survivors of any future earthquake know how far inland they need to evacuate to be safe from a tsunami.

Cherry trees were a natural choice for the memorial because in Japan the lovely but short-lived blossoms symbolize life’s sweet beauty and its fragile, fleeting nature. For at least a thousand years the Japanese have been admiring cherry blossoms each spring in outings known as hanami, or cherry blossom viewing.

Cherry trees are also being planted here in the United States. A Japanese business executive has started planting cherry trees at the National Museum of the U.S. Air Force in Dayton, Ohio to symbolize Japanese gratitude for flights of relief supplies, search and rescue missions, and reconstruction aid. This hearkens back to the first gift of Japanese cherry trees to this country a little over a century ago. Each April those trees bring thousands of visitors to Washington, D.C. to view the delicate display, a reminder of hopes for peace between the two nations.

One of the best places to view cherry blossoms in Portland is at the north end of Waterfront Park in the Japanese-American Historical Plaza. Dedicated in August 1990, the plaza’s living glory is the double row of Akebono cherry trees, a white-flowering cultivar that originated in Japan. Administered by the Oregon Nikkei  Endowment, Inc., the plaza tells the story of Portland’s Japanese and Japanese-American community. Plaques recall the forced internment in remote inland camps of people of Japanese ancestry – whether immigrants or U.S.-born citizens – during World War II. The plaza was created with support from Portland Parks & Recreation and many others, including the Metropolitan Arts Commission, Portland Development Commission, and a number of private foundations and businesses.

 Japanese Historical Plaza April 11 2011

This year the Japanese-American Historical Plaza cherry trees are scheduled to peek the week of March 9th.

Winter Tree ID at Lone Fir Cemetery

Join Urban Forestry for a Winter Tree Identification Workshop
Saturday, February 28, 2015 9:30-11:30 am
Lone Fir Cemetery – SE 26th Avenue between SE Stark and SE Morrison

Enjoy the beautiful trees of Lone Fir Cemetery while improving your tree id skills. Can you identify a tree from bud and leaf scars, bark, and twigs? Only the three heritage trees at the cemetery will be labeled (the namesake Douglas fir; the General Joseph Lane maple; and a 100-foot incense cedar!) Lone Fir is Portland’s oldest continuously used cemetery and is now a de facto arboretum, with 500 trees representing 67 species. Participants will walk the grounds and discover a new way of looking at trees without leaves. Bring your camera!

Sacramento Elementary School Learning Landscape Tree Planting

Sacramento 2003 Tree Planting

Click here for Portland Parks & Recreation Learning Landscape home page.

On February 27 Portland Parks & Recreation Urban Forestry will plant 38 trees with students, parents and teachers from Sacramento School in northeast Portland.  These trees from five continents will increase tree diversity on the school grounds and create an opportunity to learn about geography, science, arts and writing by studying these unique trees.


Improve the health of students and the surrounding environment by planting a diverse mix of trees at Sacramento School. 

Special considerations

Special emphasis will be on evergreen conifers to help buffer bitterly cold east winds from the Columbia Gorge that can strike in winter.

  • 20 conifers (including some deciduous conifers) and 6 broadleaf trees
  • More than a half of the trees will be Oregon natives
  • 4 of the trees are living fossils – ginkgo, monkey puzzle, giant sequoia, and umbrella pine
  • 2 represent trees that would have grown on the ancient supercontinent Gondwana (monkey puzzle and Tasmanian summit cedar)
  • The planting will be intentionally diverse to maximize learning opportunities:
  • Trees from at least five continents
  • Trees from 5 of the 8 countries where Portland has a sister city
  • Trees will provide visual interest for classrooms
  • Edible Asian persimmons will provide seasonal interest
  • Smaller, slower growing conifers will to provide year-round visual interest and reduce noise to the classrooms from the playgrounds

Trees are being selected for:

  • usefulness for teaching tree biology, natural history, ethnobotany and other subjects
  • many of the trees have cultural significance to Asian, Native American and other peoples
  • fall color and diverse foliage color and texture will beautify the landscape
  • longer lifespans and lower maintenance needs (no spraying)
  • value to wildlife as food or shelter
  • 10 of the trees are listed as endangered or vulnerable to extinction in the wild or near threatened

Benefits from the planting

1.     To students, trees will:

  • filter asthma-worsening air pollution from the nearby I-205 freeway and other streets
  • reduce stress-inducing noise from the nearby I-205 freeway
  • provide shade and cool the air on hot days
  • reduce the brunt of frigid east winds from the Columbia Gorge during winter

2.     To the environment, trees will provide:

  • food, roosting and nesting sites for wildlife
  • evergreen trees will provide shelter from storms and winter cold and will intercept stormwater runoff
  • greater biodiversity, with about 20 species and 14 genera in 8 tree families


Students will be planting trees all day, volunteers are needed:

8:00-10:00 am  prep for a.m. planting

10 to 12:00 pm help with morning planting, and prep for afternoon planting

1 to 2:30 pm help afternoon planting and clean-up

Students, teachers and community members are invited to celebrate the tree planting in an afternoon assembly outside at 1:30 pm.
