Adverse effects can be observed long after the end of the mine activity. The tyres of four-wheel drive vehicles and the hooves of horses and camels also destroy dune vegetation and their weight leads to greater soil compaction. When mining takes place in dune systems supporting climax a well balanced plant communities, the process of rehabilitation can take decades and may never achieve the ecological diversity of the dunes before the mining as the elasticity of dune vegetation is low.
