Abstract

Abstract Height frequency of 67 spccies was measured on 100 sites together with environmental variables. Data were analysed by correlation coefficients, association analysis of vegetation data using agglomerative “d squared centroid” method, mapping of variables using two-factor principal component analysis, and relationships between individual spccies and environmental variables using multiple and path analysis regression methods. The 21 more-abundant species for which the latter analysis was made were: Anisotome aromatica, Celmisia spectabiiis, Chionochloa rubra, Coprosma cheesemanii, C. pumita, Dacrydium laxifolium, Dracophyllum recurvum, Euphrasia cuneata, Forstera bidwillii, Gaultheria colensoi, Gentiana bellidifolia, Hebe tetragona, Notodanthonia setifolia, Ourisia vulcanica, Pentachondra pumila, Poa colensoi, Podocarpus nivalis, Rhacomitrium lanuginosum, Schoenus pauciflorus, Senecio bidwiili, and Wahlenbergia pygmaea. Environmental factors measured were: altitude, aspect, slope, depth to rock, dep...
