The Tree City USA program is designed to recognize those communities that effectively mange their public tree resources and to encourage the implementation of community tree management based upon four standards. These four standards provide a structure for a Community Forestry Program, and also help provide an awareness and appreciation of trees among New Jersey's residents.

Under the four standards, a Tree City community must have:

• an official tree board or department charged by ordinance to develop and administer a comprehensive community tree program for the care of trees on public property.
• the existance of a community tree ordinance designating a tree board or department and citing minimum standards for tree protection and maintenance.
• a comprehensive tree management program supported by $2 per capita per year and an annual work plan (for tree management).
• an official Arbor Day ceremony and proclamation.

Tree City communities receive a walnut mounted plaque, a Tree City USA flag, and highway signs for community entrances. Tree City communities are also eligible for free tube seedlings and bonus points toward grants. Awards are presented at the official New Jersey State Arbor Day Ceremony.

Tree City USA is sponsored by the National Arbor Day Foundation.
