Passage
A team of urban ecologists tracked canopy coverage across twelve mid-sized cities over a decade. In neighborhoods where residents organized volunteer planting programs, canopy density grew nearly three times faster than in comparable areas without such programs. The researchers noted that community involvement, not just funding, appeared to predict which planting efforts survived their first few summers.
