摘要

This paper presents a partial summary of findings presented in Neilan et al. (2005 and 2006). Regeneration of rainforest in old agricultural fields in Australia is largely dependent on seeds being dispersed into sites by frugivorous birds moving between remnants of original forest and patches of regrowth within the landscape. In subtropical Australia, regrowth is commonly dominated by camphor laurel, an exotic fleshy-fruited tree species, which is attractive to many frugivores. The spread of camphorlaurel in these landscapes has led to considerable debate amongst land managers. Camphor laurel is an undesirable invasive in productive farmland and some native vegetation types, but also provides important food and other resources for forest fauna. Thepotential for rainforest regeneration in camphor laurel regrowth in northeast New South Wales was investigated by surveying the frugivorous bird assemblage and rainforest plant recruitment in 24 patches of camphor laurel regrowth. Most frugivorous birdsassociated with subtropical rainforest were recorded and almost half of these (16 of 34) species were considered potential dispersers of rainforest plants. Of the 208 plant species recruited to the camphor patches, 87% were of local rainforest origin. Comparisons between the composition of the adult and recruit tree layers suggest birds have largely facilitated recruitment and later successional species are increasing in abundance over time. With careful and strategic management, regrowth dominated byfleshy-fruited exotics may provide opportunities for broadscale reforestation of degraded rainforest landscapes.
