Source-derived summary

Sigma Lambda Alpha (ΣΛΑ) is a North American scholastic honor society that recognizes academic achievement among students in the field of landscape architecture. It was established in 1977 at the University of Minnesota by the Council of Educators in Landscape Architecture.

History

Beta Alpha Sigma, an honor society for landscape architecture, allied arts, and urban planning at Michigan State University in the 1960s, inspired Sigma Lambda Alpha. In 1976, the president of the Council of Educators in Landscape Architecture (CELA), professor R. E. Toth, had the idea of establishing a collegiate honor society for landscape architecture students. The CELA executive board established Sigma Lambda Alpha was founded at University of Minnesota in Minneapolis on September 24, 1977.

Wiliam H. Snyder of the University of Idaho was appointed the first executive secretary of Sigma Lambda Alpha and was charged with convening a task force to form the society. Sigma Lambda Alpha was established as a scholastic honor society to recognize the academic achievements of landscape architecture students and help prepare them for their careers in landscape architecture. The purpose of Sigma Lambda Alpha is "to encourage, recognize, and reward academic excellence in preparation for the profession of landscape architecture". It places a strong emphasis on leadership and preserving the traditions of husbandry of the land.

Sigma Lambda Alpha was admitted to the Association of College Honor Societies in 1983 and achieved full membership in 1986.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
