Abstract

Trees found at forty home sites, Jamaica Estates, New York City, New York, were selected for study October 15 to November 7. 1995. Trees with a DBH (diameter at breast height) greater than 7.6 cm were identified and mapped at each property Density, relative density, frequency, relative frequency, basal area, relative dominance and importance values for all trees with a DBH greater than 7.6 cm were calculated. Black oak (Quercus velutina) and red oak (Quercus rubra) ranked first and second in relative dominance and importance; oaks (Quercus spp.) collectively have a relative dominance value of 81. Oaks are most numerous in the largest three size classes, (51 to 75 cm, 76 to 100 cm and greater than 100 cm) but comprise a small percentage of the two small
