Summary of mean tree height (m), crown radius (m), and canopy volume (m3) for aged-out trees and replacement trees per location 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 change (%) between aged-out and replacement trees’ measures was also calculated: ([Aged-out – Replacement] ÷ |Aged-out|) × 100%.
