Portland Celebrates Arbor Day in October

Due to our changing climate, Portland’s hot dry summers have made it more difficult for trees planted in April to succeed. By moving Arbor Day to October, we can plant new trees and take advantage of our nice wet winter months to help them get established. We are excited about this change and to provide an opportunity to work with Portlanders to plant new trees and give them the best opportunity to thrive.

About Portland Parks & Recreation Urban Forestry

The mission of PP&R’s Urban Forestry (UF) division is to manage and care for Portland's tree infrastructure in the City for current and future generations. Portland’s urban forest consists of 220,000 street trees, 1.2 million park trees, and innumerable private property trees. The Urban Forestry division is involved in managing and/or regulating these trees. UF created and implements the City of Portland's Urban Forest Management Plan, fosters community tree awareness and stewardship, develops tree policies and programs, monitors and assesses Portland’s urban forest, and issues permits for planting, pruning, and removal of public and some private trees. During extreme weather at all times of the year, UF crews respond to tree emergencies to keep you safe and the City moving.
