Dispersal and establishment of Huon pine (Lagarostrobos franklinii)

Abstract

The Tasmanian endemic Huon pine had a mast year in 1989 resulting in massive seedfall. Huon pine had extremely limited lateral seed dispersal by wind, although the chances of dispersal by water appear extremely good, due to its flotation capibilities. Green rosellas Platycercus caledonicus 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. -from Author
