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. Only those plants on the Native Plants List are allowed to be planted within the City’s Environmental Overlay Zone and the Pleasant Valley Natural Resources Overlay Zone. Native plants are also encouraged to be planted in the Greenway Overlay Zone. Click here to find your zoning.

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. In addition, species on the Nuisance Plant List cannot be planted as street trees or be installed in City required landscaping areas. For tree planting or removal permit requirements, visit the Permits page.

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.

Nuisance Tree List

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.
