^aA heat anomaly was defined as neighborhoods that were 1.25 degrees above average temperatures for the urbanized area.
^b"Adequate tree cover" is calculated based on comparing existing tree canopy to tree canopy targets that are scaled to ecoregions (forest, grassland, desert) and population density.
^c"Number of the trees needed" is estimated based on the number of new 600ft² trees (based on a medium-sized deciduous tree) needed to achieve adequate tree cover in all neighborhoods.
