Fine resolution palynology of Erua Swamp, Tongaririo, New Zealand, since the taupo tephra eruption of c. 1718 B.P.

Abstract

Fine resolution pollen analysis of a core from Erua Swamp shows that prior to the Taupo eruption of c. 1718 B.P., the site bore a dryland vegetation type on river flats. Patchy Nothofagusl Phyllocladus forest on the flats was destroyed by the eruption and replaced by Gleichenia-restionad swamp vegetation with abundant Halocarpus. Regional forest during the period from after the eruption to c. 650–560 B.P. was mixed podocarp, dominated by Dacrydium cupressinum and Prumnopitys taxifolia. A period of widespread and sustained anthropogenic destruction by fire of forest commenced c. 650–560 B.P. © 1998 Taylor & Francis Group, LLC.
