SHORT LISTS OF REPLACEMENT TREE SPECIES For replanting trees on private property Replace removed trees with something of value Trees vary greatly in how well they cool and clean the air, slow rainfall runoff, quiet sound, and serve as habitat. When choosing trees to replace those being removed, consider species that provide the highest value to the urban environment: • Evergreens: provide year-round benefits • Natives: adapted to Portland’s climate • Large trees: provide more canopy benefits than small trees • Disease-resistant species or cultivars: improve the urban forest’s resilience You may also want to consider planting trees that are longer lived, thrive in Portland’s climate, are drought tolerant (reducing water demand in the summer), or that provide habitat for wildlife (such as flowers for pollinators or seeds, fruits, or cones for birds or other wildlife). Minimum requirements for a replacement tree Replacement trees must: • Grow on average to at least 15 feet tall or more • Be reliably hardy in the Portland area • Not be an invasive species (nuisance tree) on the Portland Plant List • Not be prone to fatal pests or diseases, such as Dutch elm disease How to reduce the number of replacement trees you are required to plant Select the species you wish to plant from the following list. You can reduce the number of trees you are required to plant by choosing to plant evergreen trees. You can reduce the number further by planting trees that are also native and/or trees that mature at a medium or large size. Don’t see a tree that you’re interested in on this list? View a longer list of trees at www.portlandoregon.gov/trees/replacementtrees, or request the longer list from your Tree Inspector or from Urban Forestry at 503-823-TREE (8733) or [email protected]. For trees not on that list, contact your Tree Inspector with the botanic and common name of trees you want to plant, including cultivar or variety name, if any. The Tree Inspector can then determine whether the tree is an appropriate replacement tree.
