ASLA (American Society of Landscape Architects) has an active HALS Program which engages with the National Park Service (NPS), will help support SD HALS and will provide guidance and resources. Their mission includes recording historic landscapes in the United States and its territories through measured drawings and interpretive drawings, written histories, and large- format black and white photographs and color photographs. ASLA has an active and supportive HALS Professional Practice Network, which shares information on cultural landscapes, supports Chapter HALS committees and assists with technical information for documentation.

The National Park Service manages the HALS National program, and formulates policies, sets standards, and drafts procedural guidelines in consultation with ASLA for HALS documentation which is submitted to the Library of Congress. The Prints & Photographs Division of the Library of Congress preserves the documentation for posterity and makes it available to the general public, making it the preeminent source of documentation for historic properties.
