The Arboretum saves species that are extinct or near extinction and serves as a learning place for agricultural history.The Arboretum officially was created in 1976, and officially opened in 1979. The arboretum, which was originally a diseased orange grove, was transformed into organic gardening plots. A centerpiece of the Arboretum is the Heritage House, which was built in 1894 as the home and office of Fullerton's pioneer physician, Dr. George C. Clark. In 1972 the house was moved to what is now the middle of the Arboretum.
