More than 3,900 communities have achieved Tree City USA status by meeting four core standards of sound urban forestry management: maintaining a tree board or department, having a community tree ordinance, spending at least $2 per capita on urban forestry and celebrating Arbor Day. Today, in all fifty states, Washington, D.C., and Puerto Rico nearly 155 million Americans are living in Tree City USA towns and cities.
