Annual mortality rates (% per year) and tree counts of aged-out, existing, replacement, and additional trees per location for the baseline and each future scenario (S1–4). “Aged-out trees” refers to trees removed between baseline and future scenarios. “Existing trees” are trees that were not removed since baseline and remain in future scenarios. “Replacement trees” are new trees provided to future scenarios in place of aged-out trees. “Additional trees” are new trees that are provided to the future models to achieve scenario and location-based tree counts. S2 and S3 share tree counts and characteristics, other than S3 having some strategically placed private trees to target their shading potential for buildings. CA (climate-adapted); NA (not applicable).
