Soil Rehabilitation: Can Dung Beetles Improve Post-mining Land-use Options?
Final report of a three year study on rehabilitated South African coal mine soils, testing an invertebrate based addition to conventional rehabilitation, for environmental managers and land use planners.
by University of Pretoria | May 2018
Ants, termites, dung beetles and earthworms are known to improve soil health, but none had been deliberately applied as part of a mine reclamation strategy. Experimental and field scale studies asked whether dung beetles maintain their burial activity, and the soil services that follow, in soils typical of rehabilitated mine land, and set out recommendations for using them alongside existing methods.
