Poonthie Ruwe Conservation Park has relatively flat terrain, with very shallow loam over calcrete rock, which outcrops frequently throughout the park. The soluble nature of calcrete has lead to the formation of small ‘potholes’ throughout the park. These ‘potholes’ provide habitat for native fauna, particularly reptiles, although rabbits have been known to use these burrows in the past as well. Sandy soil has blown onto the southern edge of the property from a small, disturbed dune on the adjacent block. The name ‘Poonthie Ruwe’ means ‘Hopping Mouse Country’ in the local Ngarrindjeri language.
Eastern side of Dukes Highway 4-5 km southeast of Tailem Bend, which is 95 km southeast of Adelaide
Proclaimed as a conservation park in 2003. The park has a history of grazing which ceased from 1994 under a native vegetation heritage agreement.
The conservation park was established because of its significant area of Lomandra effusa iron-grass grassland, which is protected as Critically Endangered under the EPBC Act. The park contains 13 plant species of conservation significance.
Iron-grass Natural Temperate Grasslands of South Australia. Small area of callitris open woodland in the SE corner of park.
Spring is the best time to see the small herbaceous plants in the ecosystem growing and flowering. The southern part of the park has the best flora diversity.
Management activities have been very limited since the park was proclaimed. Some weed control and fence maintenance. Consideration currently being given to grazing and fire options to reduce the impact of annual weeds.
