This study develops a methodology for assessing the urban provisioning and cultural ecosystem services created by woody species in urban forests. Drawing on this methodology, the research examines these dynamics through use of an urban forest inventory and survey data for the city of Philadelphia. Findings quantify the percentage of species and corresponding percent of the tree population that are likely to be harvested by urban foragers in the city.
