Preparing Trees for Winter

Winter is just around the corner, and you know what that means: the possibility of tree damage from ice and snow. Trees are resilient and can usually handle a little bit of winter weather. However, even the most resilient trees can benefit from some extra attention before the snow starts to fall.

That's why Urban Forestry encourages property owners to get their trees professionally maintained, now, to reduce the possibility of any major damage this upcoming season. Care from a qualified arborist is essential to improving tree structure for maximum stability, clearing out damaged or dying limbs, and identifying hazardous trees that need to come down.

Below we have some resources to help you find the best ways to support your tree so you can be at ease no matter what weather will bring.

The City has a list of recommended Local Tree Care Providers available to aid you in your research. The companies on this list have:

• completed the City's Local Tree Care Providers Workshop within the last year
• Have a Certified Arborist or similarly credentialed tree professional on staff
• Do not have documented tree code violations or permitting application issues within the past year
• Have an active Portland business license

Some Friendly Reminders:

Property Owner Responsibilities

Property owners are responsible for maintaining trees on their property and adjacent rights-of-way. For any tree-related issues on private property, including challenging maintenance and safety concerns, contact a private arborist.

Permit Requirements

Before performing any major tree work—including pruning, removal, or addressing risks—it's necessary to understand Portland's tree permit requirements. Visit our Tree Permits and Regulations page for details on when a permit is needed.

Emergency and Maintenance Response

PP&R Urban Forestry crews are prepared to respond to hazardous tree situations across the city caused by severe weather. To report tree emergencies on City property, including public streets and roads, call 503-823-TREE and press 1 for the fastest response. For non-emergency tree issues, email Trees@PortlandOregon.gov.
