Content Summary: Interim Biogeographic Regionalisation for
Australia (IBRA) version 7.0 represents a landscape based approach
to classifying the land surface of Australia. 89 biogeographic
regions and 419 sub regions have been delineated, each reflecting a
unifying set of major environmental influences which shape the
occurrence of flora and fauna and their interaction with the
physical environment across Australia and its external territories
(excluding Antarctica). IBRA Version 7.0 data consists of two
datasets. IBRA bioregions, which is a larger scale regional
classification of homogenous ecosystems, and sub regions, which are
more localised. IBRA Version 7.0 is the result of both significant
changes to certain IBRA 6.1 boundaries, plus refinement of other
boundaries due to better data availability amongst some states and
territories, and alterations by the states/territories along state
borders. The updated boundaries were jointly defined by the
Commonwealth, State and Territory nature and conservation agencies.
In this respect refinements were carried out to all mainland
jurisdictions with significant changes in Queensland and South
Australia. In addition the dataset was also updated to more closely
conform to the Geoscience Australia 1:100K State borders, and a
standard coding/naming convention introduced (for both regions and
sub-regions) resulting in differences to both names and codes used
in earlier IBRA Versions. Various sources were used to delineate
islands - these included the GA100K Admin layer plus the Australian
Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and
the GA Commonwealth Fisheries 2006 dataset. |
