In 2001, Washington DC received a generous gift from local philanthropist Betty Brown Casey. The gift was to be dedicated to restoring the capital city's once-renowned tree canopy that gave the city its nickname "city of trees." Since the time of the initial gift. The foundation Casey Trees has involved numerous partner organizations, hundreds and volunteers, and a scientific approach to urban forestry to protect and expand DC's urban tree canopy. Each year, the foundation supports the planting of 2,500 trees across the city. Across the pond, the Greater London Authority has advanced its own urban forestry program, as demonstrated in this interactive map.
