New Zealand forest dynamics: a review of past and present vegetation responses to disturbance, and development of conceptual forest models

New Zealand forests have been and are shaped by a suite of disturbance types that vary in both their spatial extent and frequency of recurrence. Post-disturbance forest dynamics can be complex, non-linear, and involve multiple potential pathways depending on the nature of a perturbation, site conditions, and history. To capture the full range of spatial and temporal dynamics that shape forest ecosystems in a given area, we need to use and synthesise data sources that collectively capture all the relevant space-time scales.

Forest regeneration problems in the Hunua range, Auckland

[First paragraph...]
The Hunua Range consists of approximately thirty square miles of dense mature rain forest and an equal area of scrub and second growth. It is situated nearly thirty miles south-east of Auckland City on the western edge of the Firth of Thames (Fig. 1.) The range comprises a group of deeply dissected, up-faulted blocks of Mesozoic greywacke. The upland region is sharply delimited from the rolling lowlands by four well-defined fault lines in the east, south and west. To the north the area dips gradually into the Tamaki Strait and the Papakura-Clevedon lowland.

Ecology of Ship Rats (Rattus rattus) in a Kauri (Agathis australis) Forest in Northland, New Zealand

Home range dimensions and habitat use by ship rats (Rattus rattus) at Puketi, a kauri (Agathis australis) forest in Northland, were examined by live capture and radio-tracking over five weeks in September and October 1993. Home ranges of six females and five males averaged 0.86 ha in area and 174 m in length, with no significant difference in range area or length between males and females. There was substantial overlap in ranges between and within sexes.
