“…Infection, by an unidentified digenetic trematode, was observed among 4.5 per cent of frogs collected from undisturbed wetlands in the Hawkesbury River area of western Sydney (Ferraro and Burgin 1993). Individuals collected from disturbed wetlands (i.e., wetlands with urban and/or intensive farming activity within their environs and, at least partly cleared had marginally higher levels of infection.…”

“…Tyler and Davies (1985) propose habitat destruction by logging as a possible cause. In the western Sydney region, Ferraro and Burgin (1993) observed that the reduced numbers and diversity of frogs was correlated with upper storey vegetation loss. Nichols and Bamford (1985) also noted reduced diversity in rehabilitated mine sites in Western Australia.…”

“…Bradford (1991) noted that lack of vegetation around the Sierra Nevada Lakes left frogs more susceptible to predation from Blackbirds. In western Sydney, Ferraro and Burgin (1993) observed that vegetation clearance and the loss of local wetlands resulted in a concentration of birds within remaining wetlands. They proposed that the lack of frogs, and the higher incidence of trauma-induced injuries to frogs, compared with those from comparatively less disturbed sites, could be attributed to wetland degradation.…”

This paper reviews the factors involved in the decline, both inter-and intra-specific, of Australian frogs from both disturbed and apparently pristine habitats. Despite a lacl< of published accounts and an absence of long term population studies, a variety of causes were identified. Habitat changes, owing to human influences, are lowering frog numbers and species diversity. Other factors involved include heavy metals, pesticides, salinity, temperature, disease, competition from introduced species and human collection. The complex interactions and synergistic effects of these factors on frogs have yet to be fully elucidated. However, since frogs are sensitive to environmental influences at all stages of their life cycle, population studies would provide base line data to identify, at an early stage, the impact of human influence.

The potential for golf courses to support restoration of biodiversity for BioBanking offsets

In golf course development there is frequently remnant vegetation on the areas unused for infrastructure. We propose that these areas, together with a whole range of other reserves including sporting fields, cemeteries, railway reserves and educational facilities may be the source of degraded remnant vegetation and associated open space that could be used to provide offsets for biodiversity. We followed the changes in vertebrate biodiversity with low key alteration to management of the Camden Lakeside Golf Course to assess if such areas had the potential for biodiversity banking offsets. Birds, bats, frogs and reptiles increased in species diversity over time. Frogs and reptiles tended to peak in species numbers during the observational period but bat and bird diversity continued to increase. We concluded that on this 'island' within a matrix of urbanisation and cleared agricultural lands without remnant vegetation, observed changes in diversity made such areas potential sites for biodiversity banking offsets.

“…The results of this study indicate that urbanization has had a profound effect on the distribution, abundance, and diversity of anurans in central Iowa, reflecting a growing consensus throughout the world (e.g., Ferraro and Burgin 1993, Riley et al 2005. Landscape fragmentation and a decrease in habitat connectivity had the strongest influence on anuran community structure, disproportionately influencing the abundance of species associated with upland habitat use outside of the breeding season.…”
