The property known as "Tree Hill" was put up for sale in early 1970 by private owners. Arlington residents from church and civic organizations formed
Preservation Association for Tree Hill (PATH) during that summer and begin negotiating for the purchase of 21½ acres. PATH raised $10,000 in May 1971 to secure a lease with an option to purchase the parcel for $230,000. In 1971, the City of Jacksonville began providing funds for Tree Hill operations. A contractual arrangement with the
Duval County School Board began in 1974, under which Tree Hill provides elementary school instruction, teacher training, and science curriculum materials development for the school district. Legislators from Jacksonville created a state budget earmark, and $445,000 in state money was appropriated in 1974. Governor
Reubin Askew personally delivered the check to PATH, and in December, the
Florida Department of Natural Resources provided funds for the state to acquire the first 21.92 acres. In 1990, Tree Hill received 160 acres of land on the west side of Jacksonville from the estate of Martin E. Stein. later renamed Lew Brantley Park. In 2004, the center donated the remaining Stein property to the city of Jacksonville for the creation of Tillie Fowler Regional Park. The
Jacksonville Community Foundation began an Endowment Fund for Tree Hill in 2002. The www.treehill.org website was launched that year. An annual
Butterfly Festival has been held every spring since 2002. The following year, the Tree Hill organization was given $150,000 for the 5-year
naming rights to the amphitheatre, whereupon the structure was named the Joseph A. Strasser Amphitheatre. Several live displays of animals, including gopher tortoises, possums, goats, chickens, fish and snakes, were added in 2009. The nearby
Jacksonville Arboretum & Gardens was organized and is operated like Tree Hill. ==Park features==
