The site has extraordinary natural features and meets five of the nine Ramsar Convention listing criteria. It is an exceptional example of karst and coastal fen wetlands, with groundwater springs reaching more than 110 metres in depth. The pools are renowned for their water clarity and support aquatic vegetation up to 15 metres below the surface. It is one of the few remaining permanent freshwater wetlands in the lower south-east of South Australia.

The wetlands support a number of nationally threatened species, including the orange-bellied parrot and the Australasian bittern. They also provide breeding and spawning habitat for native fish species such as the Yarra pygmy perch and dwarf galaxias.

The wetlands are also culturally important. The Traditional Owners of the land, the Bunganditj (Boandik) people, and local Indigenous people of the South East have a strong connection with the site, recognising the importance of groundwater discharge and connections between culture and wetland health. The site traditionally provided food and other resources to the Bunganditj people, with middens and other evidence of occupation remaining today.

What is a karst wetland?

Karst and other underground hydrological systems are rare worldwide but are a notable wetland type in the south-east of South Australia. Karst wetlands are created by limestone rocks being dissolved over thousands of years. The water is discharged from a groundwater aquifer and is fresh, clear and cool - almost always between 14 and 15°C. Karst pools are usually permanent and can be very deep.

What difference does Ramsar-listing make?

The Convention was signed in Ramsar, Iran in 1971 and aims to halt the worldwide loss of wetlands and conserve those that remain, through wise use and management. As a member country, Australia is encouraged to add sites to the Ramsar List that contain representative, rare or unique wetlands, or wetlands that are important for conserving biological diversity.

The Piccaninnie Ponds Karst Wetlands site is now recognised as internationally important and Australia has committed to its conservation and wise use. The site is also protected under the national Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as a 'matter of national environmental significance'. The EPBC Act regulates actions that may have a significant impact on the ecological character of Ramsar sites.

Australia has an obligation to notify the Ramsar Convention Secretariat if the ecological character of a listed Ramsar site has changed, is changing, or is likely to change due to technological developments, pollution or other human-induced interference.

Piccaninnie Ponds Karst Wetlands is Crown Land managed by the South Australian Government as a conservation park under the National Parks and Wildlife Act 1972. A management plan for the Piccaninnie Ponds Karst Wetlands Ramsar site has been prepared by the South Australian Government which takes into account the Australian Ramsar Management Principles (EPBC Regulations 2000). The overarching vision of the plan is to ensure that the Piccaninnie Ponds wetlands retain their ecological, cultural and social values.
