Trees observed in complete urban municipal tree census inventories from 11 communities across north-central New Jersey. A listing of the most common species occurring in each size class by planting zone typology, their occurrence in the data set, and the maximum range observed DBH. Entries in bold italic were used within species-specific analysis, given their occurrence in adequate numbers across all planting typologies.
