Sand Mallee Dune top Remnants: Ecological Asset 7

asset-6-map-big

Description

Sand mallee dune top remnants exist largely on private lands in cleared agricultural landscape outside of large conservation reserves in highly fragmented states. Historically, dune top remnants have been valued by landholders due to their important role in stabilising soils, preventing wind erosion & buffering crops and so have remained largely uncleared.

In addition, it is believed these dune top remnants play an important role in landscape connectivity for species dispersal across the landscape. Species included in this conservation asset include the Open mallee or Ridge fruited mallee (Eucalyptus incrassata) and Beaked Red Mallee (E. socialis) and the Mallee Cyprus Pine (Callitris verrucosa).

asset7-1Threatened or Important Species

Sand mallee communities and dune top remnants are known for their high bird and reptile diversity and it is believed they are important habitat and foraging areas for small mammals such as the Sandhill Dunnart (Sminthopsis psammophila) and other heath species such as the heath goanna (Varanus rosenbergi).

Potential threats to Sand Mallee Dune top Remnants

  • Historical Land Clearance
  • Habitat Fragmentation
  • Stock and overabundant native herbivore Grazing
  • Weed invasion (such as agricultural weeds include wild turnips, mustard, pasture grasses, wild oats, onion weed / horehound and thistles)
