Abstract
- Aim: Biodiversity assessment and decisions rely on knowledge of the spatial distribution of species, yet most global biodiversity is inadequately represented by occurrence records. Efforts to improve our knowledge of biodiversity distribution include targeted taxon survey programmes aimed at generating records of new, or previously unrecorded, species. Here, we evaluate nearly 8 years of biodiversity record collection by Bush Blitz, Australia's largest species discovery programme, to test how efficiently knowledge was added through the programme. Location: Continental Australia. Methods: Because we expect locations that are environmentally distinct in comparison with those already surveyed to harbour novel records of species, we assess the extent to which Bush Blitz surveys complement continental environmental diversity (ED). We then assess how effectively this improvement in sampling of ED translates into the accumulation of records of new, or previously unrecorded, species. Our assessment is based on Bush Blitz data for six taxa (amphibians, spiders, land snails, moths and butterflies, reptiles and vascular plants), benchmarked against data accumulated over the same period by the Atlas of Living Australia (ALA)—Australia's largest aggregation of biodiversity records—as a comparison of effectiveness to the Bush Blitz programme. Results: Environments surveyed through the Bush Blitz programme are highly complementary to environments from which 'background' observations were made over the same period and aggregated in the ALA. Bush Blitz surveys result in large numbers of records of new, or previously unrecorded, species. Across most biological groups considered, additions were made highly efficiently with respect to survey effort, relative to background survey effort represented in the ALA. Main Conclusions: Our results demonstrate the ability of the Bush Blitz programme to contribute valuable data to conservation assessment and planning and the important role of surrogate‐based assessments of ED complementarity in planning new targeted biological surveys.
