Abstract	Carabid beetles were sampled by pitfall trapping on Brentmoor Heath, Surrey, UK during the summers of 2009 and 2010 to determine the effects of bare ground patch size on beetle abundance, richness and diversity. Four patch sizes were investigated: 1, 4, 25 and 100 m$^{2}$ as well as the adjacent mown and unmown areas. A range of environmental parameters relating to soil characteristics, stones and nearby vegetation were measured at each patch and control habitat in order to distinguish the effect of patch size. Results show that bare ground is a valuable habitat for carabids, but that the response of their abundance, richness and diversity to bare ground patch size depends on a large number of environmental variables on and around the patches. When all variables are taken into account, smaller patches appear to benefit carabid abundance, richness and diversity. In the presence of Molinia caerulea at the patch edges, however, larger patches were more beneficial. Given this dependence on environmental variables, the perfect patch size for conservation of biodiversity is likely to be site specific and the best approach may be to use a variety of patch sizes at a range of successional stages.
