Australian RegionWhat do we have?
Alan ButlerCSIRO Marine and Atmospheric ResearchHobart
Have a very rough draft in form of the template
• But awaiting this meeting to decide detailed treatment …• A. Some potential co-authors contacted but, again, awaiting
clarity on what I’m asking of them• B. Taxonomic groups
• Can say a little about many taxa, but details about:• Fish• Ophiuroids• Sponges• Some decapods• ?polychaetes• ?corals – soft, hard
• C. Ecosystems – coastal, offshore to upper slope• D. Australia. ??exclude subantarctic?• E. Data sources, F. Gaps, G. future directions – below
Identification Guides
• No problem to list them (though a large bibliographic task)• Many “popular”• Significant number “serious”, but some of them are out of date• ABRS pubs and a few similar are most authoritative• Costello’s criteria would narrow it down a little (e.g. illustrations)• ??include listing of authoritative faunal “catalogues” etc.?
Taxonomic expertise
• Can make a reasonable statement• Recent National Taxonomy Forum report • Survey data from ABRS 2003-6 data• Would need to get permission to list people
How many species?
• A reasonable statement can be made.• Need to be clearer about what’s required (below)
• Have some databases:• CAAB• (OBIS)• AFD • (OZCAM)
• And paper by Chapman, Numbers of Living Species in Australia and the World, 2005, now being revised
An example from Chapman (for Porifera) …

Status and threats
• Much can be said• Regional statements prepared for Regional Marine Planning in
some areas• SE
• SW
• NW
• N
• Draw on recent SoE reporting for most points• Account of the NRSMPA status, progress and difficulties
We’ve done quite a bit …but …

Australian coverage patchy
Spatially
And TaxonomicallyQuestion about inclusion
of individual survey data
Possible approaches (not mutually exclusive)
• Strictly the template• Spp (many data are just compiled for “Australia”, some for “large marine domains”)• Guides• Expertise• Status and threats etc.
• Regionalisations• Focus on groups for which a bioregionalisation has been prepared for Govt planning
purposes• Fish (combined with other data – geomorph, phys oceanogr … )
• And groups for which this has been done over restricted areas• Sponges• Ophiuroids (compared with fish)• (crustacea, polychaetes underway)
• “Whole-biota” datasets• Focus on surveys endeavouring to examine large part of the biota simultaneously, using
multiple devices and associated with physical variables• 17 or more of these (recent CERF Hub work)• Restricted locations (not all same methods)• Shelf and upper slope depths
• Methods• Place some emphasis on how to approach design and conduct of future surveys• “smart” survey design based on surrogates• Multiple devices• Interpolation and extrapolation using surrogates
What will we present?
• For whole Australian region, can fill out something like:
Taxonomic Group
Coverage and taxonomic consistency
Regional Species-number
Other forms of diversity?
%endemic
% rare % introduced
% migratory
Threatened (by listing category)
protected Source
Marine mammals Excellent DEWHA
Seabirds ****policy decision – are these “marine life”?****
Excellent ?Birds Aust?
Teleost Fish Excellent C of A 2005;Last et al. 2005;Lyne et al. 2008
Chondrichthyans Excellent Recent sharks & Rays book

Or in more detail?
• But “bioregions” vary for different purposes
• And extracting the data by bioregions would be a major project • data are now point data• Have been summarised by the Australian Govt’s large marine domains • and for some groups by the National Bioregionalisation Provinces

Marine mammals
There are 24 Provinces in the Nat Bioreg (not including subantarctic). So each row of this table gets subdivided by 24. Perhaps OK if very few taxa used. Perhaps only those in red here?
We may not want or be able to do these subdivisions here

Or, for detailed, consistent-method surveys only
• For a given survey (defined location, etc.), can fill out something like this (some headings debatable):
