The post-glacial pollen sequence for inland regions of the eastern South Island is from grass and Coprosma _ Dacrydium (probably D. bidwillii) _ Phyllocladus (probably P. alpinus) _ Podocarpus and Dacrycarpus _ Nothofagus (solandri and/or fusca). If this is interpreted simply as a response to climatic warming, the position of Dacrydium is anomalous, as at present it does not often reach altitudes as high as Phyllocladus and Nothofagus solandri var. cliffortioides.
Pollen analysis of a high altitude bog (Winterton Bog) and an alluvial soil sequence in the upper Awatere catchment on the western flanks of the Inland Kaikoura Range, and radiocarbon dates on wood and charcoal from the Marlborough region, have established a Holocene, (post 10 000 years B.P.) vegetation history for this area.
