Vulkathunha‑Gammon Ranges National Park is a protected area in the state of South Australia, situated in the northern Flinders Ranges approximately 460 km north‑east of Adelaide and near the town of Leigh Creek. The park covers an area of about 360,000 hectares (≈3,600 km²) and encompasses the Gammon Ranges, a series of rugged sandstone ridges, deep gorges, and arid plains.
History and naming
- The land was originally proclaimed as Gammon Ranges National Park in 1972.
- In 2021 the park was officially renamed Vulkathunha‑Gammon Ranges National Park to recognise the traditional name “Vulkathunha,” used by the Adnyamathanha people, the Aboriginal custodians of the region.
Geography and geology
- The park lies within the St Petersburg–Flinders Ranges geological province and consists principally of Precambrian and Cambrian sedimentary rocks, notably quartzite and sandstone that have been sculpted into dramatic cliffs, gibbers and domes.
- Elevations range from roughly 300 m in the surrounding plains to more than 700 m at the highest ridge tops.
Ecology
- Vegetation is typical of semi‑arid mallee and mulga woodlands, interspersed with pockets of chenopod shrubland and saltbush communities.
- Notable flora include the desert oak (Allocasuarina decaisneana), native grasses such as Triodia spp., and wildflower displays of Sturt’s desert pea (Swainsona formosa) after seasonal rains.
- Faunal assemblages feature several species of conservation interest, including the yellow‑footed rock‑wallaby (Petrogale xanthopus), the greater bilby (Macrotis lagotis), and avian predators such as the wedge‑tailed eagle (Aquila audax) and the peregrine falcon (Falco peregrinus).
Cultural significance
- The area is part of the traditional lands of the Adnyamathanha people, who have a long cultural connection to the landscape, its water sources, and its resources. The park’s dual name acknowledges this heritage and supports joint management initiatives.
Management
- The park is administered by the South Australian Department for Environment and Water under the National Parks and Wildlife Act 1972.
- Management objectives focus on preserving natural and cultural values, controlling invasive species (e.g., feral goats, foxes, and weeds such as Prosopis spp.), and facilitating low‑impact recreation.
Visitor information
- Access to the interior of the park is primarily via four‑wheel‑drive tracks; a self‑drive permit is required for certain remote sections.
- Designated campgrounds are available at locations such as Iron Theorem Oasis and St Petersburg, offering basic facilities (pit toilets, fire pits, and rainwater tanks).
- No sealed roads enter the park; visitors are advised to carry sufficient water, fuel, and emergency supplies.
Conservation status
- The park forms part of the larger Flinders Ranges World Heritage Area nomination, reflecting its outstanding natural and cultural significance.
