The Story

‘Lynburn’ is a property run by the Lane Family, north east of Wongan Hills at the top of the Avon River Catchment. The ‘Lynburn’ project site is a valley floor that has issues with wind erosion, run-off, waterlogging and rising salinity.

Through Wheatbelt NRM’s Soil Carbon Incentive Program the Landholders planted oil mallees, saltbush, Casuarina obesa and Melaleuca hamatas.

The Lane’s planted 3,000 oil mallees (Euc. loxophleba subsp. lissophloia) on the hillside to control wind erosion and planted 50,000 saltbush (Atriplex nummularia) for their grazing program. In addition, a mixture of 5,000 saltbush (Atriplex amnicola), 1,000 Casurina obesa and 1,000 Melaleuca hamata were planted in the more saline sites, to abate waterlogging, water erosion and the rise in the saline watertable.

Lessons learnt

  • Seedlings planted into ground that had larger amounts of ground cover ie. stubble had a greater chance of survival than those planted into bare ground.
  • Due to a dry season in 2012, the mortality rate of seedlings was high.
  • Established saltbush plantings were able to be grazed in 2012.
