Abstract
Urban foraging is an under-explored facet of the alternative food movement. This study quantifies the nutrition available from foraged products in Syracuse, New York, using four common urban species: serviceberry, mulberry, apple, and black walnut. I harvested and weighed fruit from trees of each species throughout Syracuse, at weekly intervals. I compared edible fruit tree availability to neighborhood household income.
Seasonal yield estimates were low relative to orchard crops; many trees produced no fruit. Overall, large variation was present in yield. Tree diameter was positively correlated with yield. Reasons for low yields included late spring frost, summer drought, and herbivory. Species-specific factors are also discussed. Edible trees are more available in high income neighborhoods.
During sampling I also discussed foraging with homeowners and passersby, finding strong interest in foraging. Most residents were either already foragers or expressed positive reactions. I conclude with recommendations for designing a forage-rich urban forest.
