Bioregions are large land areas characterised by broad, landscape-scale natural features and environmental processes that influence the functions of entire ecosystems. They capture geophysical patterns linked to fauna and flora at the ecosystem scale. They help researchers understand complex biodiversity patterns.
National Parks and Wildlife Service has a bioregional approach to conserving NSW biodiversity, working with large geographic scales and biological cycles. This is approach is more useful in biodiversity conservation than working within administrative boundaries.
Planning for biodiversity at this scale recognises the significance of these natural processes and provides the best means of maximising long-term biodiversity conservation. Similarly, Office of Environment and Heritage programs such as the Biobanking Scheme utilise the bioregional scale to assess and understand the adequacy of biodiversity offsets arsing from new development.
