In 1968, the Australian Conservation Foundation, Australia’s peak environmental community organisation, published a 50-page booklet, The Conservation of Norfolk Island (4.5 MB). The booklet was reprinted in 1969 and 1975. The PDF file has been optimised for web use. A scanned version with greater resolution is available (111 MB).
Along with justification for an ethic of conservation, the report includes descriptions of local areas, recommendations about conservation and appendices with lists of the species of plants and animals.
