South Park Blocks Master Plan
TREE SPECIES GUIDANCE, CONTINUED
UNIVERSITY DISTRICT EDGE Deciduous trees for non-center rows in the University District need to be species other than American elms to increase the diversity and resiliency of the South Park Blocks urban forest and allow the park’s long-term replanting strategy to meet species diversity goals. The species should share some similar characteristics to the American elm to complement and blend with University District Center trees. Trees should have a vaseshaped or wide branching form. Native tree species should be given high consideration for replacement trees in the University District. For example, native species that can be considered include: • Fraxinus latifolia (Oregon ash)
Oregon white oak
Oregon ash
Sycamore
American beech
• Quercus garryana (Oregon white oak) • Acer macrophyllum (Big leaf maple) Non-native, non-elm species currently planted in the University District that could also potentially be considered include Tilia cordata (Littleleaf linden), Acer pseudoplatanus (Sycamore maple), Fagus grandifolia (American beech), and Quercus rubra (Northern red oak).30
30 Any tree species included when referencing future planting are examples but not commitments. This reflects essential principles of dendrology and urban forest management.
