Abstract
Abstract The structure, composition, and dynamics of a rare coastal community, kanuka (Kunzea ericoides var. ericoides) shrub- and tree-heaths on sand dunes, were studied on Whale Island and at Thornton, in Bay of Plenty. Both multi-stemmed, semi-prostrate and erect kanuka is present in virtually pure stands on largely unconsolidated dunes on Whale Island, and multi-stemmed, semi-prostrate kanuka in nearly pure stands on consolidated dunes at Thornton. This and other studies indicate that lack of competition (i.e. establishment at low densities) is primarily responsible for the multi-stemmed habit, but interacting environmental (exposure, drought) and genetic factors may also play a part. All communities are floristically poor compared with other woody communities in New Zealand, with only widespread species present and a large proportion of adventives. Mean annual diameter growth was 3.0 mm/yr at Whale Island and 2.8 mm/yr at Thornton; mean annual height growth ranged from 29.8 cm/yr in younger stands (6...
