Description

Last winter, a number of dead or dying trees – mostly Raywood ashes – were removed from the Ainsworth median between NE 33rd and NE MLK Jr. Blvd.  To ensure a healthy urban forest along Ainsworth, each vacant space is being replanted this spring with a diverse mix of deciduous and evergreen trees.

Our urban forest continually faces threats from introduced pests and plant diseases, risks which may increase with climate change. Having trees from many different families and genera helps guards against losing all the trees along the boulevard from a single cause at the same time.

The Ainsworth median blocks form the city’s Linear Arboretum. As such, they are place to showcase the wide variety of trees that can successfully be grown in Portland. To learn more about the new trees and the Linear Arboretum, please join Neighborhood Tree Steward Jim Gersbach for a free guided walking tour:
