“…These often cover entire ridges and flanks extending up to altitudes of 550-600 m and arc particularly well developed on south-facing slopes. They parallel similar tangles described for areas on the west coast of South Island (Wardle 1966, Cockayne 1967 and for the Open Bay Islands (Burrows 1972 …”

The indigenous forest on Mt Karioi was surveyed in 1974-75 and the data examined using muitivariate techniques. These revealed a number ofrecognisablc communities. Altitude and aspect were the main environmental factors determining plant distribution. An abrupt change in tloristic composition at about 550 m elevation was attributed to fog. The regeneration of many tree species was threatened by a high population of goats. Some floristic differences were also noted between Mt Karioi and other mountains 111 the Waikato region.

“…Some root-stocks may support up to a dozen trunks. In some instances this multi-stemmed habit appeared to be a result of vegetative reproduction (Wardle 1966, Stewart & Veblen 1982. No evidence of layering was found however.…”

“…Weinmannia racemosa is a dominant component of many forests throughout the North, South and Stewart Islands, with a northern range limit in the Waikato region (Wardle & MacRae 1966). It is present as a light-demanding broadleaved angiosperm in most forested states in the conceptual model (Fig.…”

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. Here we integrate palaeoecological data with contemporary ecological evidence to build conceptual models describing post-disturbance dynamics in New Zealand (NZ) forests, encompassing large temporal and spatial scales. We review NZ forest disturbance regimes, focussing primarily on geological and geomorphic disturbances and weather-related disturbances but also considering the role of anthropogenic disturbance in shaping present-day NZ forests. Combining information from 58 studies of post-disturbance forest succession, we derive conceptual models and describe forest communities and forest change for conifer-angiosperm (including kauri forest), and beech forests (pure and mixed). The methods used in these studies included chronosequences, assessments of stand dynamics, longitudinal studies, palaeoecological reconstructions, and comparisons with historical observations; the temporal range of the studies extended from 15 years to millennia (c. 14 000 years BP). Our models capture the generalities of NZ forest dynamics, and can be used to support modelling and help guide decision-making in areas such as ecosystem restoration. However, this generality limits model resolution, meaning the models do not always portray the specific features of individual sites and successional pathways. There is, therefore, scope for more detailed, site-specific development and refinement of these frameworks. Finally, our models capture successional pathways and native plant communities from the past and present; invasive species, climate change, and exotic plant pathogens are likely to alter future forest dynamics in novel and unpredictable ways. These models, however, provide us with baselines against which to interpret and assess the impacts of such effects on forest composition and processes.

“…Libocedrus is capable of taking advantage of open sites, especially after wind throw (ClaytonGreene 1977, Veblen & Stewart 1982 and slipping (Clarkson 1981) and these events may provide its main opportunities for population rejuvenation. Weinmannia---its main tree competitor within the basin is also capable of regenerating on bared surfaces (Wardle 1966) and may have done this on the fresh ground surfaces provided by the Newall and Burrell eruptions (see below). However, Weinmannia is more sensitive to cool temperatures (Sakai & Wardle 1978) and strong winds than Libocedrus, and is, moreover, growing closer to its altitudinal limit.…”

“…The most probable explanation is that Weinmannia regained former ground more effectively and rapidly. Weinmannia seeAs prolifically most years, and the small, light seeds are very well suited to wind dispersal; it will also coppice after damage (Wardle 1966). There is no reason to suppose that Weinmannia would remain excluded for very long from areas in which the climatic conditions were suitable for its growth.…”
