Abstract

The choice of native vegetation is a significant factor in successful land use rehabilitation using saline CSG water in Queensland.

This research suggests while much of the soil types – chosen for their CSG values – are fixed there was a significant result for electrical conductivity (EC) (dS/m) under different vegetation on certain soils.  For example, using PERMANOVA analysis some significant results were found in red kandosol soil (P(perm)= 0.035). The difference between each soil type in terms of EC was also confirmed as significant (P(perm)=0.004).  A significant interaction between soil type and sub-replicates was achieved under cleared dryland buffel grass (P(perm)=0.025). Analysis on salt mass (t/ha) showed a significant difference between vegetation under the same red kandosol soil

Santos’s Coal Seam Gas (CSG) fields in Maranoa Region, Queensland, had been cleared for dryland pasture and later were turned into Chinchilla White Gum (CWG) (Eucalyptus argophloia) woodland, irrigated by CSG waste water as part of the beneficial use of CSG produced water.

The sites with remnant ironbark and brigalow vegetation had the least land use disruption compared to the other two land use types.  This appeared to justifying their use as native vegetation sites to represent pre-clearing for paired cleared and irrigated plantation sites.  Some salt mass and concentration losses were observed under change of land use from native vegetation to cleared dryland under red kandosol soil.
