The arboretum was established in 1963 by F. H. (Sam) Popham on approximately 7.5 acres of scrub jungle. He used a conservation approach called Assisted Natural Regeneration (ANR), encouraging naturally growing native trees instead of creating a conventional planted garden. In 1989, he gifted the original property to the Institute of Fundamental Studies (IFS), now associated with the National Institute of Fundamental Studies (NIFS). An additional 27 acres were added, bringing the site to approximately 34.5 acres. Today it is used for forest restoration, biodiversity research, environmental education and nature-based tourism. The arboretum contains dry-zone vegetation and provides habitat for numerous species of plants, birds, butterflies, dragonflies and mammals.
