documentary. a documentary is a film or video examining an event or person based on facts. the word can also refer to anything involving documents. the idea of documentary as meaning "pertaining to documents" came about at the beginning of the 19th century. later, it came to mean a factual record of something.
a new reconstruction of the vegetation cover for new zealand at the last glacial maximum (lgm) is presented, based primarily on a database of 66 pollen site records and a more limited range of plant macrofossil and coleopteran records. extensive forest is evident only from auckland northwards. conifer–broadleaf forest similar to that in the region today, but with agathis australis scarce, persisted in the far north, whilst nothofagus trees and a range of shrub taxa characterised the more open forests elsewhere in northland. survival of nothofagus-dominated forest in coastal and exposed continental shelf locations to the southwest of auckland and northwestern south island is also indicated. beyond these regions, vegetation cover comprised shrubland- and grassland-dominant communities, with the latter more prominent in eastern areas, to the south and presumably at higher altitudes. nevertheless the survival of forest trees is indicated unambiguously in most regions apart from the eastern south island. thus the concept of ‘micro glacial forest refugia’ in new zealand remains supported by this latest glacial vegetation reconstruction and we draw possible parallels with the developing but contentious concept of ‘northern cryptic refugia’ in europe. recent assertions that pollen and beetle reconstructions of the new zealand lgm vegetation patterns diverge significantly are not supported by this analysis. rather, the two proxies are readily reconciled if the term ‘woody’ as indicated by coleoptera is not restricted to tall forest trees but extended to the widespread woody shrub and small tree elements of the new zealand flora.
