  • Key Takeaway: Managing Seattle’s urban forest involves coordination across eight different city departments, treating trees as essential infrastructure.
  • Summary: Jana Dilley, an urban forester for Seattle, notes that trees are part of the city’s infrastructure, requiring collaboration between multiple departments like Parks and Transportation. Canopy cover analysis guides planting decisions, but neighborhood-level temperature data is crucial for prioritizing tree placement to combat heat exposure. Poorer neighborhoods, often shaped by historical redlining, are disproportionately hotter and need trees for environmental justice.

  • Key Takeaway: Successful urban tree planting requires selecting the right species for the site and ensuring species diversity to build resilience against pests and disease.
  • Summary: Selecting trees involves considering their mature size, future climate suitability, and proximity to infrastructure like power lines and buildings. Cities must avoid overplanting any single species, similar to diversifying a stock portfolio, to maintain resilience against pests and diseases. Planting itself is complex, often involving removing rubble and improving poor urban soils, which adds significant cost.
