Resilience & Urban Shade Equity

“Shade: It’s a civic resource, an index of inequality, and a requirement for public health. Shade should be a mandate for urban designers.” - Sam Bloch

You may have walked past them 100 times without noticing, but the street trees you pass every day are actually “green infrastructure” that make your neighborhood a more healthy, beautiful place to live. You can quantify exactly how those trees are supporting you with this iTree tool. So the next time you walk by, say “thanks.”
Trees:

What is Urban Forestry? It is the planting, maintenance, care, and protection of all trees in a city by volunteers and professionals to optimize the benefits listed above for all. In early 2022, Yale hosted a terrific speaker series with current research on climate resiliency & equity.

Ideally, every neighborhood would have plenty of life-giving shade trees, but it became tragically evident that this is not the case when 60 Portland neighbors passed away during the June 2021 heat dome event. These deaths occurred in neighborhoods 25 degrees hotter than those with adequate shade. Several Portland-based community organizations have formed the Shade Equity Coalition to help remedy disparities in street tree canopy. Each voice and every action is needed to help prepare our city for a changing climate. Explore Shade Tree Equity Scores.


Portland’s older neighborhoods have ample space to grow large shade trees.

Portland’s Tree Programs

Advocates are hoping for a more integrated approach to green infrastructure with a new form of government coming to Portland in 2025.

  • A Bike Portland interview with Matt Glazewski describes how Portland's current form of government is an obstacle to collaborative action on climate preparedness and mitigation.

  • OPB explored how inter-bureau personnel dynamics impair Portland’s ability to reach canopy goals, July 2022.

  • Columbia Slough Watershed Council 2021 two-part series on
    Portland tree planting programs

  • Joint introductory overview of urban green infrastructure in Portland by BES staffer Jennifer Karps and a PPR Urban Forester Jenn Cairo in 2020. Listen to the audio here [1:20] and follow along with the slides [start at #29].

Tools to improve shade equity:

In order to achieve tree equity, U.S. cities must plant 552 million trees. Portland listed as one of 20 cities that stand to gain the most by improving shade tree equity.

Every tree has a story. Share the ones you know at the Canopy Story mapping project.

What you can do:

Appreciate neighbors who care for trees, big & small.

A tree equity score indicates whether there are enough trees in a neighborhood for everyone to experience the health, economic and climate benefits that shade trees provide
