The Concordia Neighborhood has a long median where community members and Neighborhood Tree Stewards have planted nearly 60 species of street trees.   Help neighbors and City staff maintain these trees by mulching and pruning.  Dress in appropriate work gear.  Tools provided.  Click here to view a map of the Ainsworth Linear Arboretum.
