Native and Nuisance Trees

Information

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

Both plant lists are integral to the City of Portland’s natural resource protection program and invasive species management strategy.

Plants from the Native Tree List and Nuisance Tree list are allowed or not allowed depending on certain city planning zones. Find your zoning.

Native Tree List

Native trees provide many ecosystem benefits, such as wildlife habitat and storm-water interception. Native trees are also well-suited and adapted to Portland's climate.

Only those plants on the Native Plants List are allowed to be planted within the following City planning zones:

  • Environmental Overlay Zone
  • Pleasant Valley Natural Resources Overlay Zone

Native plants are also encouraged to be planted in the Greenway Overlay Zone.
