Under History’s Canopy – Revealing the Layered Landscape of The Arboretum

There are particular challenges facing stewards of large-scale cultural landscapes, including  accommodating layers of history, adapting to changes in setting and contemporary requirements, and ongoing interpretive, treatment, and maintenance issues. The compilation of a comprehensive cultural landscape study is an invaluable tool in addressing these issues. This workshop provides an overview of cultural landscape reports using the Los Angeles County Arboretum & Botanic Garden and its recently completed Cultural Landscape and Treatment Plan as a case study.

The land that became the Arboretum was originally part of the Rancho Santa Anita and home to Arcadia’s founder and first Mayor, Elias Jackson “Lucky” Baldwin. In 1947 the State of California and the County of Los Angeles jointly purchased 111 acres, including Baldwin’s home site, in order to establish a public botanic garden and arboretum. In 1950, architect Harry Bent Sims produced a Master Plan, which organized the Arboretum into distinct planting sections by geographic provenance, separated by circulation elements, with contributions by landscape architect Edward Huntsman-Trout.

The Cultural Landscape and Treatment Plan documents and illuminates the site’s complex history, and is being used to help enrich visitor experience, inform landscape treatment and development, and preserve garden heritage and sense of place.


This Workshop is in Partnership with The Los Angeles County Arboretum and Botanic Garden
