The standards of Tree City USA are comparatively simple and mainly composed of qualitative indexes, which emphasize ordinance establishment, publicity, longterm planning for urban forestry development, participation and coordination among functional departments of government, social organizations, nongovernment organizations and ordinary citizens.
