Nuisance Tree List

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. The plants identified on the Nuisance Plants List are prohibited from being planted within the Environmental Overlay Zone, Greenway Overlay Zone, and the Pleasant Valley Natural Resources Overlay Zone. Click here to find your zoning. In addition, species on the Nuisance Plant List cannot be planted as street trees or be installed in City required landscaping areas.
