Sustainable production from rehabilitated coal mine pastures in southern Queensland’s Brigalow Region – Acland grazing trial results

A central aim of rehabilitation is to ensure that disturbed land is returned to a post-mine condition that is safe, stable and self-sustaining. This paper describes initial results from a grazing trial at the New Acland open-cut coal mine in southern Queensland (-27.27 lat, 151.72 long) that aims to assess the sustainability and viability of cattle production from rehabilitated mined land compared to production from surrounding unmined lands (Newsome 2014). The grazing trial was established in 2013 by the Acland Pastoral Company, a subsidiary of New Hope Coal, on lands previously used for dairying, beef and crops before open cut coal mining of the Walloon coal measures began in 2002. The area has a mean annual rainfall of 640 mm. Local soils, typically dermosols and vertosols derived from sandstones or overlying basalt flows, are suited to grazing but are marginal for cropping.CITATION:Clewett, J F, Newsome, T, Paton, C, Bennett, J, Melland, A, Eberhard, J and Baillie, C, 2018.
