Tree Volume Equations for Fifteen Urban Species in California

"This study is the first phase of a three-phase urban forest utilization project at Cal Poly, San Luis Obispo. Selected samples of fifteen urban species were carefully measured in order to develop tree volume equations. These species include Chinese Elm, Holly Oak, Camphor Tree, Jacaranda, American Sweet Gum, Monterey Pine, Blue Gum, Monterey Cypress, Acacia (golden wattle), Carob, Modesto Ash, Southern Magnolia, Sawleaf Zelkova, London Plane, and Chinese Pistache. Equations for species in three regions (Southland, Coastal and Central Valley) of California were developed. The results of all regions are completed and reported here. Local and standard volume equations were developed for use by urban foresters needing to calculate tree volumes."
