There are two overarching management pressures influencing urban greening today—and the two forces are seemingly in tension. On the one hand, municipal foresters, arborists, and other professionals managing the urban and peri-urban forest are urged to increase the diversity of street- and park-tree plantings, especially at the genus level. On the other hand, stewards of the urban and peri-urban forest are also urged to only or primarily plant native tree species. There are ways, however, to resolve the tension between favoring natives and promoting diversity—without resorting to nonnatives. (A, U, M, Bp, Bm)
