The National Park Service (NPS) administers the planning and operation of the Historic American Landscapes Survey (HALS), which includes: selecting and approving landscapes for documentation, standardizing formats and developing guidelines for recording landscapes, catalogs and/or publishing the information when appropriate.
The Library of Congress accepts and preserves HALS documents, furnishes reproductions of material, and makes records available to NPS.
The ASLA Professional Practice department works with ASLA’s Historic Preservation Professional Practice Network (HP PPN) to provide advice on identifying, selecting, and documenting historical landscapes. The ASLA HP PPN, through its HALS Subcommittee, oversees the nationwide identification of historic landscapes that merit HALS documentation.
