Human civilization has left its footprint on every part of the planet, in the process driving what is frequently referred to as the sixth mass extinction1,2. Conservation prioritisation requires a rigorous assessment of vulnerable species as well as their habitats to develop effective priorities for conservation. However, the data needed to develop such priorities with rigour are often lacking. Biodiversity integration and synthesis is an important empirical step to identify priorities in maximising the already limited funds allocated to conservation3. The diversity and distribution of a subset of terrestrial vertebrates have become an umbrella for taxonomic and spatial conservation, despite the known biases present in popular open datasets4,5. Efforts to mitigate extinction risks or protect key habitats often disproportionately focus on particular taxa, ecosystems, or regions6,7. This approach neglects many other equally important species and their habitats and compromising the maintenance of ecosystem services provided by diverse functional groups8,9.
