The arboretum of 40 trees established at the Southern Oregon Experiment Station in 1961 was a joint project of the Siskiyou District of the Oregon Federation of Garden Clubs, Jackson and Josephine County Extension Services and the Southern Oregon Agricultural Experiment Station. Extension Agent John W. McLoughlin managed the project.
After Claire Hanley’s death in June 1963, the Siskiyou District voted to name the arboretum in her honor for her contributions to regional and statewide garden clubs.
Claire Hanley had served many posts, including president of the Jacksonville Garden Club and the Oregon Federation of Garden Clubs. She was chairman of a scholarship fund that continues to bear her name today.
The Experiment Station is known today as the Southern Oregon Research and Extension Center, located at 569 Hanley Road in Medford. Jackson County purchased the property in 1957, a portion of the Hanley family farm.
The Claire Hanley Arboretum has been enhanced with specimen trees, shrubs, flowerbeds, paths and landscaping. Many of the original trees are massive today, some of them still bearing their original tin markers.
