Abstract

Aboveground forest carbon sequestration is known to be a function of allometric relationships, stand history, and edaphic conditions. We investigate how the heterogeneous edaphic conditions of a naturally assembled urban brownfield influence the allometric relationships of the dominant species Betula populifolia Marsh. We measured diameter at breast height (DBH), height, mass and age on four sites that exhibited considerable edaphic differences. Site conditions did not appear to impact total tree mass to diameter relationships. However, mean DBH at the various sites ranged from 6.7 to 9.8 cm and the mean height from 637.4 to 911.8 cm. In addition, above ground woody biomass ranged from 40017 to 71935 kg ha−1. Apparently resource allocation between growth and maintenance within the heterogeneous edaphic conditions of the urban context clearly results in considerably different growth rates and stocking densities. These results help to establish accurate metrics for the development of inventory-based forest carbon allocation models within the difficult environs of the urban context.
