The temporal stability of estimates of demographic behaviour for a sample population of A. Cunninghamii was analysed using a stage-classified (Lefkovitch) matrix model. Despite the similarity of estimates from life-table analysis for the finite rate of natural increase, lambda, from previously published data and from a further 5 years of field data, the sets of data showed marked differences. The relative contibutions of survival, growth and fecundity to the observed population growth rate (elasticity) remained similar for both analyses. Survival rate contributes most significantly to the achieved population growth rate, and this appears typical of long-lived plant species. Elasticity is proposed as a measure for classifying species using the competitive (C), stress-tolerant (S) and ruderal (R) model of plant strategies.
