Information on reporting tree emergencies, defining "emergencies" and "non-emergencies," and when the City gets involved.
On this page

Helpful Definitions 

  • Emergency: An imminent threat (immediate hazard) to public safety or infrastructure that is time sensitive. 
    • By contrast, a dead tree (for example) maynot qualify as an imminent threat, if this tree work could be permitted in a standard time frame. 
  • Retroactive Permit: A permit applied for after doing emergency tree work. 
  • Right-of-way (ROW): City-owned property, often a strip of land near a street. Tree emergencies in the ROW are handled by the City and Urban Forestry. 

Report a Tree Emergency

A blocked/imminent threat to the public in the Right-of-Way or City-managed land.

  • The City of Portland - Urban Forestry will respond during all hours to tree emergencies that block or pose an imminent threat to the public in the right-of-way (street or sidewalk) or on City-managed land (parks, etc.)
    • Tree or large branches blocking right-of-way that are too large for you to safely move out of the way
    • Street Tree suddenly split ( fresh, white sapwood visible in a deep crack in the trunk, or where the main branches attach to the trunk)
    • Street Tree or park tree suddenly leaning ( cracks may appear in the soil if the tree starts to uproot)
    • Large hanging limb over street or sidewalk
    • Report a Tree Emergency

        • Press #1 for Tree Emergency Hotline
          • Transfers to emergency dispatch if call received after regular business hours
  • Non-emergency See examples on this page or on Reporting Non-Emergency Tree Problems page.
  • What problems will the City not respond to? 
    • Neighbor's yard tree is hanging over my property.
    • Tree Emergency on private property that does not impact the street or sidewalk
      • We recommend calling an arborist to remove the hazard, then apply for a retroactive permit. 
      • If it is a life-threatening situation call 911 for assistance.
    • For more information see Private Property Tree Emergencies below. 

Private Property Tree Emergencies

If the emergency exists on private property and is NOT blocking or threatening the right-of-way or City-managed land, Urban Forestry suggests that you contact an arborist to remove the hazardous portion of the tree.

A retroactive permit is required for any work that generally requires permitting (Pruning, Removal and Replacement Permits), this option is only for emergencies when a hazard to people or property is imminent. 

Retroactive Permits for Emergency Tree Work

  • You must apply for a permit within 7 days after doing emergency tree work on a regulated private property tree
  • Photographic evidence is required
  • See the Report a Tree Emergency page for more information 

Emergency Tree Removal

Useful information on what is and is not an "immediate hazard" that necessitates tree removal.​​​​

Tree Diseases and Pests

Information on common tree diseases and pests, including information on symptoms, susceptible species, and treatments.

Dutch elm disease, or DED, is one of the most destructive plant pathogens in the United States and Europe, having killed millions of elms and persisting despite efforts to control it. With approximately 3,500 susceptible elms throughout the city, DED would have a catastrophic impact on Portland’s urban forest if allowed to prevail unchecked. PP&R Urban Forestry works diligently to manage the impact of DED in Portland.

Portland Parks & Recreation's Integrated Pest Management (IPM) program manages pests that are harmful to the health, function or aesthetic value of park landscapes in an efficient, effective, and environmentally responsible manner, while paying careful attention to public and employee safety.

Native and Nuisance Trees

The Portland Plant List is comprised of two lists and supporting information: the Native Plants List and the Nuisance Plants List.
