The unpredictable desert fringe
The original proposal for a Simpson Desert National Park included Cravens Peak. This reserve protects gibber plains, red sandy dune fields, semi-permanent
waterholes, Coolabah woodlands, and one of the richest reptile
assemblages on earth.
While marginal and unpredictable for production, the relatively moist and fertile dune swales and temporary waterbodies are an important oasis for many desert animals that retreat in the dry times from the desert proper. Our protection of Ethabuka and Cravens Peak gives the desert back it's
fringe and its refuge for wildlife against the harshest conditions.
The northern summer rains brush the northern edge of the Simpson, the southern winter rains just brush the south. Erratically, huge systems douse the lot. A large number of regional and international migrant waterbirds follow the rains to make the most of the sudden burst of productivity.
The plants are patient. The gidgea and ironwood will wait a century or
two to successfully set a new generation. The spinifex waits decades and
the seeds of hundreds of short-lived wildflowers rest under the sand.
The soft edges of dunes run into large sandy plains and the low, rugged
Toko and Tooma ranges, which are rich with fossils 500 million years
old. The Mulligan River snakes along the north-eastern boundary of the

What this reserve protects
Cravens Peak is a hot bed for reptiles, including the woma, a rare desert python that has become extinct across a third of its former range. Cravens Peak also protects:
- Mulgara (nationally vulnerable)
- Grey falcon
- Painted finch
- Ridge-tailed monitor
- Inland ningaui
- Australian bustard
- Spinifex pigeon
- Ariadna's ctenotus (a rare skink)
- Red-bud mallee
- Hummock (spinifex) grassland
- Mitchell-grass plains
- Gidgee woodland
What we’re doing on the property
Cravens Peak has buildings, bores and hundreds of kilometres of fences and tracks to maintain. Surrounded by farming, its boundaries have to be maintained and incursions of stock responsibly managed.
We're also working with The University of Sydney who are researching specific
control techniques for feral predators such as cats and foxes. Feral camels who enter the property from the desert to the
south must also be controlled.
While the weed list is small, there is some weed control work and we are vigilant on new intruders.

Fire-stick farming comes full circle
Large-scale and intense wildfires have become an unfortunate characteristic of Australia's arid zones since the removal of traditional Aboriginal fire-stick farming.
They're particularly problematic after big wet seasons, which massively increase plant growth - especially highly flammable grasses such as spinifex.
In the past such growth was kept under control by the Wangkamadla people, who regularly burnt the area as part of their land management.
Now Cravens Peak staff are attempting to reinstate similar patterns of ‘fire-stick' farming, as reserve managers control natural lightning strike ignited burns and implement planned ‘mosaic burns' designed to encourage new growth and act as fire breaks.
Wildfires can seriously affect populations of small native mammals, so fire management is of critical importance.
Now that cattle have been removed and damage from feral camels and horses reduced, we're seeing rapid improvement in the Mitchell grass plains and wetland areas. We're also seeing regeneration of the gidgee and mulga woodland vegetation between the dunes. This has led to increases in the numbers of small mammals.
Satellite images have shown plant cover and productivity in the swales between dunes and on the slopes of the ranges is higher than surrounding properties and measurably improved since our purchase of the land.
History and cultural values
Cravens Peak Reserve is part of Wangkamadla country. The Wangkamadla have a long-standing connection to this land, with rock paintings and significant sites scattered across the reserve.
The reserve once lay on a trade route stretching from Queensland's Gulf of Carpentaria all the way to South Australia. The local narcotic plant pituri was traded for stone knives, seashells and even dugong-tusk daggers.
We're working closely with the Wangkamadla people to identify and learn about important cultural values.
