Some physiological explanations for the distribution of kauri

[Abstract of a paper read at the Ecological Society Conference, 1983.]

First paragraph:
The future of New Zealand's kauri forests, from both preservation and management aspects, lies with the regenerating stands which cover some 100,000 ha of land in the northern North Island. Factors influencing the distribution of these kauri stands are discussed, and the influence of light, temperature and water availability shown to have major effects on the siting of the species. The tendency of kauri to associate in almost pure stands, especially on ridges, is explained by the interaction of physical factors. Similar interactions influence the location of the southern limit of kauri.
