Whilst the importance of good soil condition in grazed systems has long been recognised, grazing management in tropical savannas has historically focussed on the maintenance of perennial grasses and scant attention has been paid to the soil. In this paper we briefly discuss the role of perennial grasses and soil macroinvertebrates in maintaining ecological function and soil health and the effects of grazing on these elements. However, our understanding of these relationships remains poor. For example, the respective roles of, and interactions between, perennial plants and soil macroinvertebrates in promoting soil health and ecological function, and how grazing affects these processes, are all poorly understood. ...
