Biologically Important Areas (BIAs)

Biologically Important Areas (BIAs) are regions where aggregations of individuals of a particular species are known or likely to display important behaviors such as breeding, foraging, nesting or migration. They have been identified from the literature and using expert scientific knowledge about species' distribution, abundance and behavior. BIAs were created to inform decision-making under the EPBC Act, and have been defined for a selection of protected species only. These selected species where chosen based on their conservation status and the availability of reliable spatial and scientific information.
