Urban Forest Mortality in Baltimore
David J. Nowak
Daniel E. Crane
Based on permanent plot measurements (1999-2001), the urban forest in Baltimore, Maryland, has an annual mortality rate 6.6% with an overall annual net change in the number of live trees of -4.2%. Various factors were found to significantly influence mortality rates. These factors will be discussed as well as its implications for carbon storage and sequestration by Baltimore's urban forest. Given the existing mortality rate and estimate growth rate, Baltimore’s urban forest is projected to decline in both number of trees and canopy area over the next century.
