Abstract

Huon pine had a mast year in 1989 resulting in massive seedfall. It was found that Huon pine had extremely limited lateral seed dispersal by wind, although the chances of dispersal by water appear extremely good, due to its flotation capabilities. Green rosellas (Platycercus caledonicus Gmelin) were observed feeding on the seed and may play some role both as predators and dispersers of seed. A low percentage of successful germination was achieved and germination rate was slow. Seedlings appear to establish mostly on soil substrates but also occur on logs and trunks. Colonisation, even downstream, can take a considerable period of time and may partly explain the restricted distribution of Huon pine. The implications of these results for conservation and management are discussed.
