| Popis: | The vegetation history of three upland valleys in the Arrowsmith Range is deduced from pollen and macrofossil analysis of buried plant debris and peat, deposited at intervals through the Aranuian period. The evidence is supplemented by information from dated charcoal layers in the soils and from surface logs, knowledge of the modern pollen rain, and the present composition and distribution of the woody plant flora. The vegetation history is interpreted in the light of episodes of glacial advance and retreat and periods of alluviation. There are no direct data for reconstruction of early Aranuian (c. 14 000–10 000 yr B.P.) vegetation although probably it was mainly herbaceous. From the beginning of the middle Aranuian (10 000–6000 yr B.P.) Phyllocladus alpinus assumed dominance. This lasted until very late in the late Aranuian (6000–0 yr B.P.). In the latter part of the middle Aranuian, Podocarpus hallii was common and Prumnopitys taxifolia was almost certainly present, together with various angio... |
