100 Trees for 100 Years: Planting the first 100 to Thrive

Planting 100 trees is the first step in a street tree succession plan– a campaign to unite the neighborhood and foster community norms and inspire individual actions that will sustain an optimal street tree canopy through time—preserving valuable existing trees, filling empty planting spaces, and replacing dead, dying, or dangerous trees.  Overall, the plan is based on best practices as defined by professional municipal arborists.  It also includes education and outreach to neighbors, and the selection and purchase of choice nursery stock.  The aim is not only to plant trees, but also to create strategies that ensure that property owners, whatever their personal preferences, now and in the future, act in the interests of the community’s canopy—making sure not only these first 100 trees but also successive hundreds thrive for their life-spans—100 years and more. 

Scope of planting campaign

The target audience is comprised of individuals who own individual properties that will change hands over the lifetime of the trees.  Since the Eastmoreland Golf Course and Reed College are expected to remain in city and college ownership, respectively, the campaign focuses on the residential portion of Eastmoreland as its geographic area.  The target tree spaces are those in non-development covered by the programmatic planting permit that Urban Forestry issues to Friends of Trees, our partner in the planting. 

Actions in the campaign—

The first planting of the 100 trees will require three main efforts leading up to the planting.

  1. Education and Outreach efforts, including, but not limited to the following mentioned by past and current board members:
    1. presentations regarding available trees
    1. 4th of July outreach
    1. newletter articles, person-to-person conversations
    1. strategies and materials to make sure maintaining the trees becomes the neighborhood norm
  2. Research and funding with which to secure the trees on the lists endorsed by the neighborhood.
  3. Tree lists, specific to the neighborhood, which are designed to change when conditions warrant based on the following organizational principles: 
    1. Diversity metric used by municipal arborists nationwide:  no more than 5% of one species, 10% of one genus, and 20% of one family in a population of trees to reduce risks, or replacement on the list when pests and diseases or a failure to thrive threatens a tree type
    1. Right tree-right place metric used to ensure that long-lived trees with as large a canopy volume as possible are planted in appropriately sized in-ground and overhead spaces 
    1. Division of the neighborhood into north-south and east-west lists that we adopted in response to the ENA board wishing to honor original planting decisions.
