Coastal dolphins are increasingly exposed to cumulative anthropogenic pressures. In South Australian gulfs and adjacent coastal waters, key threats to Indo-Pacific bottlenose (Tursiops aduncus) and common dolphins (Delphinus delphis) include recreational and commercial fisheries interactions, vessel traffic, habitat degradation, and climate change. Changing climatic conditions and increased risk of environmental perturbations are likely to influence future dolphin habitat suitability and alter exposure to anthropogenic pressures. To support spatial risk assessments of cumulative impacts, we developed species-specific habitat suitability models using MaxEnt species distribution modelling and projected future dolphin habitat suitability under three IPCC climate scenarios. Results under current climate conditions indicated that bottlenose dolphins prefer shallow coastal waters, with highest predicted habitat suitability in mid- and northern gulf areas, while common dolphins were associated with deeper waters, with highest habitat suitability predicted in southern and mid-gulf areas. Integrating these current and future species-specific habitat suitability models with spatial data on anthropogenic pressures will enable identification of areas where high-quality dolphin habitat overlaps with human activity. This approach enables development of spatial risk assessments for targeted management and mitigation strategies to prioritise protection of bottlenose and common dolphins in South Australian waters and address cumulative impacts on the marine environment.
