This pilot to test carbon driven solutions to salinity looks at the potential for carbon sequestration by salt tolerant vegetation in the NAR.
Saline land can sequester substantial amounts of carbon. The access to moisture and use of salt tolerant species seem to be the main reason for this.
There was considerable variation in carbon sequestration between species and planting layouts. Ranging between 121 tonnes of CO2-e/ha after 23 years on an alley planting of trees to 8 tonnes of CO2-e/ha after 11 years on a grazed saltbush paddock.
Planting in saline areas provides other considerable cobenefits such as improved wildlife habitat, mitigating land degradation and fodder reserves for paddocks.
Data generally estimates higher rates of carbon sequestration than the FullCAM model suggested. FullCAM is the calculation engine which supports the estimation of carbon stock change in Australia’s forests and agricultural systems.
Sale of carbon credits may provide a modest income from otherwise unproductive land.
The pilot to test carbon driven solutions to salinity is a collaborative project between NACC, the Department of Agriculture and Food WA and the Forest Products Commission. The project is funded by the Western Australian Governments State NRM Program..
