NOTE: A review is being undertaken of Biologically Important Areas of regionally significant marine species, now referred to as Biologically Important Areas for protected marine species (BIAs). Species that have been reviewed have been removed from this original BIA dataset and are available in an updated dataset. Go to the Biologically Important Areas for protected marine species web page for more information.Work was originally undertaken through the marine bioregional planning program to identify, describe and map biologically important areas (BIAs) for protected species under the EPBC Act. This work resulted in the publication of this BIA dataset in 2011. BIAs spatially and temporally define areas where protected species display biologically important behaviours (including breeding, foraging, resting or migration), based on the best available scientific information. These areas are those parts of a marine region that are particularly important for the conservation of protected species. In collecting information on BIAs, the Department has explicitly aimed to collect information about known important areas and about areas that are likely to be or may be important for a protected species. This approach was taken to ensure that: the BIAs identified did not simply represent survey effort but identified areas that scientists consider are likely to be biologically important for a protected species.BIAs are accompanied by comprehensive data attributes which enable decision-makers and people proposing to undertake actions that may have a significant impact on matters of national environmental significance to assess the relevance of the information to their specific circumstances. BIAs were initially captured on a regional basis and each region has a different list of regionally significant species. For more information about BIAs and their capture please refer to the Marine Bioregional plans http://www.environment.gov.au/topics/marine/marine-bioregional-plans and the associated report cards for each region.BIAs have been identified for the following species:Dolphins:Australian Snubfin Dolphin (Orcaella heinsohni)Indo-Pacific Humpback Dolphin (Sousa chinensis)Indo-Pacific/Spotted Bottlenose Dolphin (Tursiops aduncus)Dugong:Dugong (Dugong dugon)Marine Turtles:Flatback Turtle (Natator depressus)Green Turtle (Chelonia mydas)Hawksbill Turtle (Eretmochelys imbricata)Leatherback Turtle (Dermochelys coriacea)Loggerhead Turtle (Caretta caretta)Olive Ridley Turtle (Lepidochelys olivacea)Sawfish (Rays):Dwarf Sawfish (Pristis clavata)Largetooth Sawfish (Pristis pristis).

Polygons are attributed with the region where most of the polygon occurs.Note: This dataset was originally published in 2011, and was updated in 2015. Some further minor updates and corrections were made to the dataset in June 2024 and January 2025.All BIA data can be viewed via the Australian Marine Spatial Information System (AMSIS).BIA data are available under CC BY licence.
