Mature Canopy (LAI 4.2)

Built Structure
Exposed Asphalt
Simulation Horizon 11 Years
Annual Canopy Loss 2.1% / yr
Epidemiological & Microclimate Telemetry Preservation Focus
Projected Canopy 26.2% Baseline: 28.5% mature
Avoided Heat Mortality 14.6% Relative to unmitigated loss
Sapling-Only Cooling Deficit -1.8 °F Lost evapotranspiration vs mature
Sapling-Years Debt 24.5 yrs Time needed for parity
Key Empirical Finding: Protecting 1 mature oak prevents immediate localized heat spikes that require ~25 sapling growth-years to recover. In vulnerable urban core tracts, canopy retention yields immediate reduction in heat-related emergency admissions and mortality.
