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, Paiau, Puerto Rico, Republic of the Marshall Islands, and the U.S. Virgin Islands), and the District of Columbia.

Through public-private partnerships, NASF seeks to discuss, develop, sponsor and promote programs and activities which will advance the practice of sustainable forestry, the conservation and protection of forest lands and associated resources and the establishment and protection of forests in the urban environment.

NASF also works with regional organizations – the Northeastern Area Association of State Foresters (NAASF), the Southern Group of State Foresters (SGSF), and the Council of Western State Foresters (CWSF) – to support forest management practices and policies unique to the regional characteristics and needs of our diverse forest resources in the United States.
