| Popis: | The sediment record of Whangape Harbour shows that there were significant fluctuations in depositional energy in the harbour during the period from c >8000 cal yr B P to some time within the last millenium, and that fluvial influences increased as the harbour infilled The pollen record (highly discontinuous) from Whangape Harbour indicates that conifer‐hardwood forest covered the hills surrounding the harbour during this period The main canopy conifers were Dacrydium and Prumnopitys taxifolia, with some Libocedrus, Dacrycarpus, and Phyllocladus Agathis was also present Common canopy hardwoods were Metrosideros and, in the latter part of the period, Elaeocarpus Ascarina and Cyathea were abundant in the sub‐canopy Leptospermum grew on disturbed areas fringing the estuary Marsh or swamp environments probably never developed on a large scale in the harbour Avicennia, extremely under‐represented in the pollen flora, has been present on tidal flats in the harbour since at least c 2500 cal yr B P Large‐scale ant... |
