Age Structure and Dynamics of a Podocarp--Broadleaf Forest in Tongariro National Park, New Zealand

Regeneration patterns of three emergent conifers (Dacrydium cupressinum, Prumnopitys ferruginea and P. taxifolia) and three broadleaved canopy species (Elaeocarpus dentatus, Nestegis cunninghamii and Weinmannia racemosa) were inferred from population age structures and spatial patterns in podocarp-broadleaf forest in Tongariro National Park, North Island, New Zealand. Age data were obtained from three clear-felled plots. All three podocarp species had highly discontinuous age-distributions, with different age ranges reflecting differing light requirements and longevities of the three species (...)
