Table S8.

Summary of tree count (and percentage of total trees) for existing, replacement, and additional trees per size class for each future scenario (S1–4). “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. Size class was based on species-specific mature tree height: > 15 m (large); 10-15 m (medium); and < 10 m (small). CA (climate-adapted); CoV (City of Vancouver).
