%X A trapping study of small mammals within heath communities near Cape Otway was conducted during April-August 1989. The purpose was to describe the distribution patterns of several small mammals in relation to a floristic and structural description of the vegetation. Two species of rodent (Rattus lutreolus, R. fuscipes), two species of dasyurid (Antechinus stuartii, A. minimus) and one species of bandicoot (Isoodon obesulus) were trapped frequently enough for statistical analysis. A. stuartii was trapped significantly more often in the Heathy Open-forest than in the Closed Heath community, in contrast to A. minimus and R. lutreolus, which were captured significantly more often in Closed Heath. There was no significant difference in the distributions of R. fuscipes and I. obesulus between communities. Within the Closed Heath community only R. fuscipes displayed significant distribution patterns between sub-communities. In the Heathy Open-forest the distribution of captures among sub-communities varied significantly for both species of Antechinus and for R. lutreolus. Floristic and structural cues, as well as ground cover, were associated with the spatial distribution of dasyurid and rodent species. Bandicoot dispersion was associated only with vertical vegetation diversity. The importance of interspecific avoidance in contributing to the observed distribution patterns of both dasyurid and rat species cannot be dismissed.
