Staying close to home this summer? Then now is the perfect time to travel to the trees!
Lindens are blooming, Douglas-fir cones are ripening, and Oregon white oaks are creating some amazing shade. Visit one of Portland’s Pop-Up Arboreta and connect with the trees in our city Parks.

Berrydale, Gabriel, Irving, and University Park are July’s Pop-Up Arboreta sites. Before you head out, check out the park’s Pop-Up Map to make sure you see them all!


We have two great activities designed to get you out among the trees and having fun. These activities can be done anywhere you find trees — at a Pop-Up Arboreta, your local park, or along your street.

Download and print the activities, then go on a tree adventure!
  • Tree Journal – Seek out six common trees in Portland to learn about. Great for students in pre-school through elementary.
  • Tree Scavenger Hunt – Complete short challenges, activities, and trivia to get you interacting with our urban trees. Three levels are available for pre-school through adults.


Submit a photo of your activity by September 30, 2020 HERE and you will receive a small prize in the mail!

Rigler Elementary School Pop-Up Arboretum: Pop-Ups are not just for parks anymore! We are excited to share that Bruce Nelson, a dedicated volunteer in the Cully neighborhood, has created a neighborhood Pop-Up Arboretum at Rigler Elementary School. You can visit the school grounds at 5401 NE Prescott Street to see 70 signs, translated into English and Spanish, with information about the trees on campus. 
Remember – do not go into parks or onto trails if you cannot stay at least 6 feet away from other people. Respect park facility closures, such as playgrounds and athletic fields. Current information is posted at

Portland Parks & Recreation has monitored the COVID-19 situation since it began. We continue to be in communication with and to follow the guidance of the Centers for Disease Control and Prevention, the Oregon Health Authority, Multnomah County Health Department, and the Portland Bureau of Emergency Management regarding the situation.

Threats to Urban Trees: Pests, Pathogens and Drought


What do you think is the most concerning threat to our urban forest?
Over 70% of the more than 50 attendees to last week's online webinar recognized that drought is the greatest threat to our trees.
Nik Desai of Urban Forestry introduced attendees to the common pests and pathogens you might see in Portland. He also discussed ways to respond to them.
Following the workshop, 80% of attendees said they would care for their tree, including summer watering. This is great news because, on an individual basis, drought stress is something we can have an impact on!
Looking for New Members: Urban Forestry Commission Seeks Your Voice
A 2019 group photo of some members of the Urban Forestry Commission.
The Urban Forestry Commission is made up of volunteers. They advocate for the urban forest by advising the City of Portland.
Even before we are born, trees may be making a difference in our lives. So, how do we make sure that everyone has access to them? Being involved before decisions are made is an important first step!

Until August 31, 2020, you can apply to join a group of volunteers known as the Urban Forestry Commission (UFC).

This group hears about laws and plans affecting trees, and how money is spent to make our urban forest the best that it can be. They get access to information that the rest of us may not have the time or energy to find ourselves.

Then, they have lively discussions and make thoughtful recommendations to: The City Forester, Parks Director, and City Council.
Do you feel like your neighborhood or community has a voice in Portland? If you had a chance to be involved in the decisions that impact the entire city, would you do it?
If you would, then now is the time!

Here is what we are looking for:

All ages and levels of experience
  • Never been on a committee before? No problem!
  • Tree knowledge not necessary, but really liking them is helpful
You are an advocate for equity
  • You can bring experience about communities that have long been left out of the decision-making process
  • Ideally, you can represent a neighborhood that is both low income and low canopy
You are available to attend meetings and participate in the discussions
  • Those lively discussions only happen if you are there!
  • Monthly meetings take place on the third Thursday of each month from 9:30 am to noon
  • Meeting location is usually Portland City Hall. Currently, meetings are online only.
This is an important decision, and we encourage you to learn more about it. We look forward to meeting you!

The City of Portland seeks to build diverse representation on advisory bodies in terms of race, ethnicity, disability, gender identity, sexual orientation, national origin, age, religion, and geographic identification, as well as advocacy experience, community involvement, volunteerism, occupation, and education.

We appreciate that so many of our loyal readers are opening Tree Bark regularly. We kindly request that you share this opening on the UFC with others who may not receive our newsletter. Thank you in advance!

November Levy Proposed to Support Portland Parks: Portland Parks & Recreation (PP&R) has asked City Council to place a levy on the November ballot. This would be a critical first step in setting the bureau on the path for a Sustainable Future. To protect and restore recreation programs, parks services, and our natural areas, the levy is a crucial part of an effort to end PP&R's previous, mandated reliance on fees to fund its budget. Learn more about why we are asking for a parks levy by reading this newsletter. Please take our survey, and see how much PP&R means to Portlanders in this short and shareable video.
Watering Trees During Soak-It-Week Summer: Remember when we said how big of a problem drought is for trees? Trees for Life Oregon wants to help! They have declared the last week in July and the last week in August to be Soak-It-Weeks for watering yard and street trees. From their website, "Come get a free, pre-drilled bucket designed to water your trees this summer!" For more information, visit their website here.
