This study presents new palynological data from Caution Bay, south-central Papua New Guinea (PNG). It explores Holocene mangrove transitional events along a tide-dominated shoreline, and expands reconstructive detail for the wider southern PNG lowlands. Coinciding with recent regional archaeological research, this study also holds implications for interpretations of the Holocene settlement of Caution Bay and long-term people-landscape interactions. Data demonstrate a late-Holocene mangrove to mudflat transition, with vegetation patterns largely a function of low sediment loading, sedimentary redistributions and salinisation upon sea level decline c. 2000 cal. Yr BP. These trends appear unique to Caution Bay, highlighting a variety of Holocene shoreline vegetation changes along the PNG south coast, each dependent on geomorphologic setting and hydrological fluxes. Further work is required to elucidate vegetation change inland of the coastal zone. Greater understanding of burning patterns and an archaeological collaboration are required to determine more concisely dryland plant spatial and temporal variability.
