Street Tree Analysis

The Street Tree Analysis examined a sample data set of 2,300 trees to extrapolate baseline data for the entire street tree population in San Francisco, to determine whether or not our street trees provided the city with enough accrued benefits to justify the expense in managing the resource. Ultimately, the study describes San Francisco’s street tree population as a dynamic and valuable resource.

The report includes recommendations to improve the health and functionality of our street trees, including:

  • Focus new plantings with proven, long-lived species that maximize available growth space
  • Increase planting in districts with the fewest trees to provide more equitable distribution of benefits
  • Increase pruning frequency to improve tree functionality and longevity
  • Control costs through cost-sharing and efficient organization
