The Alliance for Historic Landscape Preservation is an interdisciplinary professional organization which provides a forum for communication and exchange of information among its members. It is dedicated to the preservation and conservation of historic landscapes in all their variety, from formal gardens and public parks to rural and natural expanses.
The Alliance was founded in 1978, when a small group of people from diverse backgrounds met at New Harmony, Indiana, to share their mutual interests and concerns about the growing field of landscape preservation. From this initial symposium came recognition of the need for increased commitment to the interdisciplinary nature of the field.
Today the Alliance is an international organization with members from more than 30 U.S. states, several Canadian provinces and Europe. Members include educators, private practitioners and representatives from non-profit organizations and government agencies. Geography, history, horticulture, landscape architecture, planning, public administration and architecture are just some of the professional specialties represented. This multi-faceted character is one of the great strengths of the Alliance.
The Alliance is incorporated in Wisconsin as a non-profit organization.
