Species nominations not prioritised for assessment

Species nominations no longer eligible for automatic consideration

The following nominations have been considered for prioritisation by Committee for two consecutive years and are no longer eligible for automatic consideration for prioritisation. If additional information becomes available a new nomination could be submitted for consideration for prioritisation.

Species name Years considered Reasons the Threatened Species Scientific Committee (the Committee) recommended that the nomination was not prioritised
Alopias vulpinus (thresher shark) 2011 & 2012

The thresher shark is found in Australia in temperate waters off southern Australia, from Brisbane, Queensland to the North West Shelf off Western Australia, including Tasmania.

On the basis of available data the Committee considers it unlikely that the species would meet any listing criterion at this time.

Canis lupus ssp. dingo (dingo) 2010 & 2011 & 2012

The dingo is found across Australia, in all states and territories except Tasmania. It has been affected by land clearing, agricultural practices, urbanisation, hybridisation with domestic dogs, lethal control, state and territory laws and, in the earlier part of the 20th century the erection of the Dingo Barrier Fence.

The Committee found that this species presents a complex range of issues, relating particularly to definition of species’ bounds, cultural and ecological significance, interbreeding with wild dogs, and contested management and legislative requirements at regional, state and national levels. The Committee recommended the dingo not be prioritised, but that the merits of developing a wildlife conservation plan should be investigated.

Carcharhinus longimanus (oceanic whitetip shark)

2011 & 2012

The oceanic whitetip shark occurs throughout Australian waters, generally restricted to warmer waters from Sydney north to central Western Australia. Threats include overfishing, both targeted (product harvesting and legal trade) and by-catch.

On the basis of available data the Committee considers it unlikely that the species would meet any listing criterion at this time.

Carcharhinus plumbeus (sandbar shark)

2010 &2011

The sandbar shark is widely distributed in Australian waters. In Western Australian waters the biomass of this species has been demonstrated to have decreased to 35% of pre-fishing levels. However, the Committee considers there are insufficient data on the population size and magnitude of decline throughout its national extent to facilitate assessment.

Carcharinus leucas (bull shark)

2010 &2011

This nomination was not given priority for assessment as there was insufficient information to undertake an assessment at the time. In particular, there is a need for more information regarding the status of this species within Australian waters, including any possible decline in numbers and the nature and extent of the threats acting on it. The species has a broad geographic distribution around the northern coastline, to as far south as Perth (WA) and Sydney (NSW).

Cycas rumphii (a cycad)

2007 & 2008

There is likely to be a conservation benefit in assessing this nomination for listing and sufficient information to undertake an assessment.  However, there are insufficient resources at this time to give this nomination priority over those recommended for assessment because the species’ ecological role is not as substantial and the level of threat acting on the species is not as high as other nominations.

The species will be covered under a regional recovery plan for Christmas Island which is currently being developed.

Nomination - Cycas rumphii (a cycad) (PDF - 247.26 KB) | (DOC - 120.5 KB)

Falco subniger (black falcon)

2010 &2011

The species is distributed over a very wide area and existing data to demonstrate population trends across its range are inadequate.

Four large macropods: Macropus fuliginosus, Macropus giganteus, Macropus robustus robustus and M. erubescens, Macropus rufus

2012 & 2013

The Committee considered that the nomination was unlikely to succeed for any of the four species. The evidence provided did not appropriately address, and was not likely to meet, any criteria for listing. The nomination also failed to adequately address the status of the four species across the full national extent.

Isurus paucus (longfin mako)

2009 & 2010

This nomination has not been given priority for assessment as there is insufficient information to undertake an assessment at this time.

Nomination - Isurus paucus (longfin mako) (PDF - 405.88 KB) | (DOC - 227.5 KB)

Lamna nasus (porbeagle)

2011 & 2012

The porbeagle is found in continental and oceanic waters around the southern half of the continent from southern Queensland to southern Western Australia.

On the basis of available data the Committee considers it unlikely that the species would meet any listing criteria at this time.

Nomination - Lamna nasus (porbeagle) (PDF - 530.56 KB) | (DOC - 453 KB)

Manta alfredi (reef manta ray)

2012 & 2013

Overall and across all regions, there is a paucity of reliable information on relative decline, either historical or recent, of both species of manta (FAO panel for CITES, 2012).

The species is listed by the IUCN as vulnerable at a global scale. The rate of population reduction appears to be high in several regions, up to as much as 80% over the last three generations (approximately 75 years), and globally a decline of 30% is strongly suspected, however, populations are likely to be stable in locations where they receive significant protection, such as Australia (IUCN, 2011).

Olax obcordata (sweetheart leaves)

2012 & 2013

The only extant populations are protected in a high conservation status reserve, and there are no clear causes of decline. Therefore, listing would have limited additional benefit at this time.

Orcaella heinsohni (Australian snubfin dolphin)

2011 & 2012

It occurs in small and localised subpopulations, some of which face recognised threats including incidental by-catch, port development, and other habitat loss and degradation. In a few locations there are detailed quantitative data on population size, structure and habitat use. However, detailed relevant information on location, population size and trends is lacking throughout most of the species’ national extent. Whilst there is some additional anecdotal information on its ecology and threats, collectively the available information is unlikely to be sufficient to demonstrate that this species meets any of the criteria for listing.

The Australian Government has recently funded several research projects through the Bill Dawbin Post-Doctoral Fellowship Fund and the Australian Marine Mammal Grants Program that will assist in providing further information on location, population size and trends for the species over coming years. The Committee suggests the development and implementation of a Wildlife Conservation Plan, incorporating this and other coastal dolphin species, could be considered as an effective management response.

Species – possible future consideration

The following nominations are either with the state/territory authority for consideration for state listing prior to being consider for national listing or have not been prioritised but are eligible for consideration in the next assessment cycle.

Species name Years considered Reasons the Threatened Species Scientific Committee (the Committee) recommended that the nomination was not prioritised
Acizzia keithi (Keith’s plant louse) 2010 & 2011

This nomination has not been given priority for assessment as there is insufficient information to undertake an assessment at this time. Keith’s plant-louse occurs in the Blue Mountains National Park on a plant species that is listed as vulnerable under the EPBC Act. Keith’s plant-louse is threatened because its host plant is threatened (by inappropriate fire regime, habitat clearing and Phytophthora cinnamomi). Given that its host plant already has the protection of EPBC listing, Keith’s plant-louse should benefit from conservation actions already underway. This nomination has been considered twice by the Committee and will not be considered again under the EPBC Act unless re-nominated due to a change in its threat status.

Acizzia veski (Vesk’s plant-louse) 2010 & 2011

The nomination for this species is being assessed by Western Australia as part of the list alignment partnership with that state.

Adclarkia cameroni (Brigalow woodland snail) 2012 & 2013

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Adclarkia dulacca (Dulacca woodland snail) 2012 & 2013

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Callistemon purpurascens (a bottlebrush) 2012 &2013

The nomination details important information relating to the distribution of, and threats to, this putative species (endemic to New South Wales). However, the description of the taxon has not yet been accepted for publication, and more information is required before publication can occur. The Committee suggests deferring consideration of this nomination until after the taxonomy is clarified.

Carmichaelia exsul 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Coprosma inopinata 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Coprosma sp. nov. 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Eucalyptus macarthurii (Camden woollybutt) 2012 &2013

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Geniostoma huttonii 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Lepidorrhachis mooreana (little mountain palm) 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Macroderma gigas (ghost bat) 2013

There is likely to be a conservation benefit in assessing this nominated species for listing, however, this species will be assessed as part of the consideration of the outcomes of the Mammal Action Plan, which is currently being finalised. This species is not recommended for inclusion on the 2013 PPAL. It is eligible for reconsideration in 2014.

Passiflora herbertiana subsp. insulae-howei 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Polystichum moorei (rock shield fern) 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Pteropus conspicillatus (spectacled flying-fox) 2013

The spectacled flying-fox was nominated for delisting from its current status of Vulnerable. However, there is some evidence that the species has in fact undergone further decline over recent years. Surveys to understand population dynamics are ongoing as part of the four-year National Flying Fox Monitoring Program, which commenced in 2012. Given that this program is ongoing, the Committee does not recommend the spectacled flying-fox for the 2013 PPAL. The species may be reconsidered for inclusion on a future PPAL once trends are quantified by the monitoring data.

Solanum bauerianum (bridal flower (Lord Lowe Island)) 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.

Sousa chinensis (Indo-Pacific humpback dolphin) 2013

There are insufficient data on the population size and trend of the Indo-Pacific humpback dolphin throughout its northern Australian range; it is therefore data deficient. Some information on population size and trend for Indo-Pacific humpback dolphins are available for some locations. However, these data are insufficient to enable assessment of the species’ status against any of the criteria at its national extent. In addition, The Australian Government is currently drafting a research strategy for tropical inshore dolphins. The purpose of this strategy is to generate scientific data that can be used to assess the conservation status of a number of tropical inshore dolphin species, including the Indo-Pacific humpback dolphin.

Stiphodon atratus (emerald cling goby) 2013

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Stiphodon birdsong (emerald cling goby) 2013

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Stiphodon rutilaureus (orange cling goby) 2013

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Trisyntopa scatophaga (antbed parrot moth) 2010 & 2011

The nomination for this species will be assessed by Queensland as part of the list alignment partnership with that state.

Westralunio carteri (Carter's freshwater mussel) 2013

The nomination for this species will be assessed by Western Australia as part of the list alignment partnership with that state.

Xylosma parvifolium 2009 & 2010

The nomination for this species is being assessed by New South Wales as part of the list alignment partnership with that state.
