The vegetation at these sites has been surveyed and analysed in a previous study (O’Leary et al. Ten sites across peri-urban areas of Melbourne, in south-eastern Australia, were selected to evaluate their bird communities (Table 1). We conclude that birds are a useful bioindicator of habitat health and that the inclusion of avian monitoring programs could improve the evaluation of the efficacy of restoration projects. This is important, particularly in light of the long-term decline in ground dwelling bird communities across the temperate regions of the continent. undulatum provides habitat for birds, there is a difference in the relative proportions of different functional groups. undulatum canopy, strong differences were detected with fewer birds and fewer species relative to the diversity and abundance of birds in the Eucalyptus overstory. However, when invaded areas were examined at a finer scale by partitioning the observations into ‘above’ or ‘within’ and ‘below’ the dense P. undulatum had fewer carnivorous birds but overall there did not appear to be any strong influence on species richness, or density.
undulatum populations at different times. We compared the species richness, density and functionality of local resident bird communities across original remnant vegetation and invaded areas with those that had been cleared of invasive P. Its removal from nature reserves across temperate south eastern Australia has been effective in allowing many plant communities to recover, but the impact on birds is unknown. undulatum is the cause of major declines in biodiversity of flora and the total suppression of regeneration of Eucalyptus. In the Azores, for example, it is associated with changes in bird communities. Pittosporum undulatum is an Australian native tree that has become highly invasive in areas well outside its original range within Australia and in many other regions of the world. Here we examined whether or not bird communities recovered following removal of a native, invasive tree in South Eastern Australia with a view to evaluating whether this could be used as a tool for assessing the effectiveness of the remediation programs. Faunal responses have received less attention.
Restoration programs, therefore, largely focus on the recovery of the vegetation. Invasive plants can lead to significant changes in the abundance and diversity of the existing flora.
