American Society of Landscape Architects

Founded in 1899, the American Society of Landscape Architects (ASLA) is the professional association for landscape architects in the United States, representing more than 15,000 members. The Society’s mission is to advance landscape architecture through advocacy, communication, education, and fellowship. Sustainability has been part of ASLA’s mission since its founding and is an overarching value that informs all of the Society’s programs and operations. ASLA has been a leader in demonstrating the benefits of green infrastructure and resilient development practices through the creation of its own green roof, co-development of the SITES® Rating System, and the creation of publicly-accessible sustainable design resources.
