Archived: Final decisions for the 2012 Red List

2011-2012 Forum topics Final decisions

The attached spreadsheet lists the results of the 2012 forum consultations, subject to approval and ratification by IUCN. Please use the filters to look for your region or species group of interest.

Any discussions of species for which we do not feel we have had sufficient feedback to enable us to make a decision are to be held open and we will continue to seek comments on these species for the 2013 update. The species for which discussions are to be held open are marked ‘pend’ in the spreadsheet.

The comprehensive 2012 Red List update will be fully launched on the BirdLife and IUCN websites in late May 2012, and we discourage significant publicity of any status changes before this point – please email if you need further information or would like to discuss publicity based on the 2012 status changes.

    Could you please put the spreadsheet in xls file format? My computer can’t open xlsm files.

    Please note that a corrected version of the spreadsheet has been posted to better reflect the previous taxonomic treatment of the species being discussed. Under ‘Existing category’, NR stands for ‘Not recognised’ and concerns species that are newly recognised at the point of the 2012 Red List update, whilst UR stands for ‘Under review’ and concerns species that were recognised at the point of the 2011 Red List update but had not yet been assessed.

    A further revision to the spreadsheet now enables users to see the changes in taxonomic order.

  4. The decision to uplist many Amazonian taxa because of projected deforestation is plain wrong when one considers that the loss of Australia’s equally diverse southwestern forests and a number of very rare species is irreversible under presently observed rates of anthropogenic climate change. A number of species, notably the Noisy Scrub Bird, Western Bristlebird and Baudin’s Black Cockatoo, are likely to lose their entire habitat to rapidly declining rainfall.

    Since 1967, the May to August rainfall over southwestern Australia has declined by something like 30 percent, from an average of 450 millimetres before 1967 to 320 millimetres since 2006. Over the coast from Geraldton to Cape Leeuwin, the decline reaches a whopping 40 percent. A currently-occurring record dry July, with Perth not reaching half its previous record low for the month and no rain forecast in remaining days, suggests the rate of change is increasing as more greenhouse gases are added to the atmosphere. Climate models suggest that the descending edge of the Hadley circulation has shifted about seven degrees poleward since 1967, even with few data before 1980.

    If we assume a continuation of present rates of decline of about 1.1 percent per annum, May to August rainfall over southwestern Australia by 2050 will be no more than two-fifths that observed before anthropogenic global warming took hold. That would mean even the wettest areas would receive annual rainfalls of 500 to 700 millimetres (versus 1,300 pre-1967), which would be completely inadequate to support the tall forests historically found there.

    For species such as the three listed above and even those of a lower threat level endemic to the wet forests of the far southwest (White-Breated Robin, Red-Winged Fairywren), observed and likely rainfall declines warrant a higher threat level than currently listed. There needs to be come collaboration between IUCN, the CSIRO and BOM to understand the rapidity of climate change in Western Australia and create international awareness of the issue.

      Response from Stephen Garnett (Charles Darwin University):

      You are right, Julien, to draw attention to the drying of south-west Western Australia – though not all the south coast has dried out – near Esperance there was even a slight increase over the last century (which should favour the western ground parrot at least). The implications of climate change on projected bird abundance is certainly something that BirdLife Australia is looking at in detail at the moment. Having assessed the status of all species and subspecies of Australian bird for the Action Plan for Australian Birds 2010, where we looked at existing evidence of climate related effects in making our assessments, we began work on modelling the future climate space and habitat suitability of all the taxa with a grant from the National Climate Change Adaptation Research Facility, in partnership that includes BirdLife International, BirdLife Australia, CSIRO, James Cook University and Charles Darwin University. We hope to have the manuscript of a book outlining adaptation strategies for the taxa we consider most sensitive to climate change finished by the end of the year. It will be interesting to see how the south-west birds stack up against those on mountain tops in north Queensland or some of the other taxa whose climate envelopes are predicted to shrink or shift.
