The predicted relative mean number of hollow-bearing trees ha⁻¹ in urban greenspace over 300 years for a combination of values for: the maximum standing life of trees and the number of seedlings ha⁻¹ (A); and the maximum standing life of trees and the rate of hollow formation (represented by the coefficient for the probability of hollow occurrence; B).
