Abstract
Multivariate analyses of 25 mature agathis
australis (kauri) stands extending from te paki to katikati are presented . four groups of kauri-nothofagus truncate, kauri- beilschmiedia tarairi, dyoxylum spectabile , kauri-ixerba brexioides , ackama rosaefolia and kauri-oleria rani, phyllocladus trichomanoides may be recognized. In
most stands however, the overlapping species distribution indicated the relative homogenous nature of the various kauri forests . imilarities between canopy and understory classification/ordination imply that canopy and understory species are correlatd in their occurrence. Stand groupings obtained by multivariate analyses showed distinct relationships to soils group . higher values (basal are and density) of kauri were recorded on soils derived from predominantly igneous rocks. The relationship between multivariate results and overall community and topographically attributes were assessed . density values and slope showed a significant correlation with ordination axes.
