“…Land uses in this region differ in their impact on plant (Venter et al, 1989;O'Connor et al, 2003;O'Connor, 2005;Walters et al, 2006) and animal (Rowe-Rowe, 1982;Samways and Moore, 1991;Samways and Sergeev, 1997;Armstrong et al, 1998;Davis et al, 1999) composition and diversity, and on ecosystem functioning (Du Toit and Du Preez, 1995;Dickens and Graham, 1998;Dye, 2000;Mills and Fey, 2004;Mills et al, 2005). These studies are insufficient for assessing the relative impact of different land uses because they have compared only a few land uses or a limited number of response variables.…”
