Topics surveyed in this paper summarize the characteristic magnitude, diversity, and complexity of Australian Aborigine rock art in the uppermost part of the Northern Territory; they are as follows: climatic conditions; most concentrated locations; techniques (dry and wet pigments, beeswax, etc.) and combinations of techniques; styles; subjects depicted; depth of the chronological range; spiritual content and significance seen both traditionally and at the present time. These remarks introduce a discussion of conservation work and site management measures implemented at the Kakadu National Park since its creation in 1979. Under the direction of D. Gillespie, a number of researchers have identified, studied, and reported the major causes of rock art deterioration in Kakadu, water being the most serious, followed by damage from mud wasps, termites, algae, and humans. The steps taken to protect the sites against these dangers are reported, and include observations on the limitations presented by silicone driplines.
