In the mid 1960s, with an increasing amount of waste needing disposal, Ryde Council looked to an expansion of the small tip in the Field of Mars Reserve. Council proposed to pipe Buffalo and Stranger's Creeks to facilitate a landfill area to a depth of up to 15m feet which could then be redeveloped into playing fields. Local residents united to form the Antitip Action Group and lobbied to reverse Council's plans for a tip at the Field of Mars. The tip was moved to Porter's Creek which to this day still requires substantial funds to control the environmental damage arising from past use as a tipsite. With the Field of Mars saved the Society was established in January 1966. In September 1966, Ryde Council advised the Society that it agreed to their proposal to development of the Field of Mars Reserve as a flora and fauna sanctuary. Hard work over following decades has seen restoration of old degraded areas of the Field of Mars and protection of the area as a Wildlife Refuge. A Visitors Centre was built and then the Environmental Education Centre which is visited by about 10,000 students each year.
