Summary of canopy cover (ha and %) of total sandbox area, as well as parcel- and street segment-based mean, associated with trees aged out since baseline (2020) and replacement trees for each scenario. “Aged-out trees” refers to trees removed between baseline and future scenarios. “Replacement trees” are new trees provided to future scenarios in place of aged-out trees. The percent decrease (%) between aged-out and replacement trees’ canopy cover was also calculated: ([Aged-out – Replacement] ÷ |Aged-out|) × 100%.
| Scenario | Location | Aged-out total area (ha [%]) | Replacement total area (ha [%]) | Percent decrease total area (%) | Aged-out mean area (ha [%]) | Replacement mean area (ha [%]) | Percent decrease mean area (%) |
