Tree Inventory

Looking for more detail on trees beyond the Arboretum? From 2011 to 2016 Portland Urban Forestry inventoried street trees over the whole city, mapping more than 200,000 to the genus level or better. Note that records for the Linear Arboretum are more detailed - usually down to species and often to the cultivar level - and current as of January 2022. Take a look at this interactive GIS tree inventory map from the City of Portland.
