Context This paper is one of a series on the natural history of Two Peoples Bay Nature Reserve on the south coast of Western Australia. Methods Landforms and soils of the Reserve were mapped by W. M. McArthur and G. A. Bartle in the mid- to late 1980s with some verification by K. A. Evans in 2023–2024. Key results A map of the landforms and soils of the Reserve is presented. The complex and variable topography and soils have arisen through a combination of in-situ weathering processes, transportation of dune sands, and lacustrine deposition. Conclusions The topography and soils of the Two Peoples Bay Nature Reserve are complex and variable. Implications The distribution of the landforms and soils of the Reserve can be explained by the geological and geomorphological framework described in the paper.
