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:
Reduce energy use, preventing CO2 emissions through direct shading (buildings) and lowering ambient summer temperatures by shading pavement/concrete; they also slow winter wind velocity
Provide mental and physiological health benefits including cognition and attention restoration esp. during COVID-19
Provide habitat for birds, insects and nourish soil life
Absorb atmospheric carbon, storing it in roots, trunk, and limbs
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.

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:
Portland leaders have heard our demands to take action on tree inequity and deadly urban heat islands. In fall 2022, Council approved $40M in PCEF funds to expand tree canopy in priority neighborhoods. Track PCEF developments and share your ideas and feedback. Encourage Portland leaders to implement the 2018 Citywide Tree Planting Strategy, start maintaining street trees, and invest in BIPOC workforce development.
