Historic Overview of HALS
In October 2000 the National Park Service officially established the Historic American Landscapes Survey (HALS), as a sister program to the Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER). Since that time, the American Society of Landscapes Architects (ASLA) Historic Preservation Professional Practice Network (HP-PPN) [formerly ASLA Historic Preservation Professional Interest Group] has been working with the National Park Service and the Library of Congress to develop the HALS program. Each of these organizations has key responsibilities in the development of the program as outlined in the HALS Responsibilities of ASLA document below.
One of the responsibilites the ASLA HP-PPN is currently undertaking is the nationwide identification of historic landscapes that merit HALS documentation. Working through the ASLA chapters and their designated HALS liaisons, a HALS toolkit has been prepared to guide volunteers through the identification and collection of data on historic landscapes. Download the HALS Toolkit below for further information, or email Susan Crook at scrookla@netzero.com.
Because the NPS created the HALS program with no permanent funding, ASLA is spearheading an effort to pursue long-term federal funding, corporate donors, individual private donations, and partnerships with interested organizations and instituions.
You may send donations to HALS Donation, HABS/HAER Foundation, National Building Museum, 441 F Street, NW, Suite 312, Washington, DC 20001-2728.

Anyone with comments, interest in volunteering or assisting with the development of HALS, please email hals@asla.org.
