NASF is a non-profit organization that represents the directors of all 50 state forestry agencies, the eight U.S. territories (American Samoa, the Federated States of Micronesia, Guam, the Northern Marianas Islands, Palau, Puerto Rico, Republic of the Marshall Islands, and the U.S. Virgin Islands), and the District of Columbia.

Though primarily responsible for forests on state and privately owned lands, State Foresters continually work with their partners in federal agencies such as the U.S. Forest Service (USFS). State Foresters deliver a number of USFS programs aimed at assisting private landowners in managing their forested lands as well as protecting those lands from insects, fire and disease.

To find specific guidance and information on purchasing, planting or caring for trees, NASF recommends you contact the forestry agency in your state to have a local forestry professional provide the best possible advice.
