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 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.
