General background information about listing threatened species

The Australian Government helps protect species at risk of extinction by listing them as threatened under Part 13 of the EPBC Act. Once listed under the EPBC Act, the species becomes a Matter of National Environmental Significance (MNES) and must be protected from significant impacts through the assessment and approval provisions of the EPBC Act. More information about threatened species is available on the department’s website at: http://www.environment.gov.au/biodiversity/threatened/index.html.

Public nominations to list threatened species under the EPBC Act are received annually by the Department. In order to determine if a species is eligible for listing as threatened under the EPBC Act, the Threatened Species Scientific Committee (the Committee) undertakes a rigorous scientific assessment of its status to determine if the species is eligible for listing against a set of criteria. These criteria are available on the Department’s website at: http://www.environment.gov.au/system/files/pages/d72dfd1a-f0d8-4699-8d43- 5d95bbb02428/files/tssc-guidelines-assessing-species-2018.pdf.

As part of the assessment process, the Committee consults with the public and stakeholders to obtain specific details about the species, as well as advice on what conservation actions might be appropriate. Information provided through the consultation process is considered by the Committee in its assessment. The Committee provides its advice on the assessment (together with comments received) to the Minister regarding the eligibility of the species for listing under a particular category and what conservation actions might be appropriate. The Minister decides to add, or not to add, the species to the list of threatened species under the EPBC Act. More detailed information about the listing process is at: http://www.environment.gov.au/biodiversity/threatened/nominations.html.

To promote the recovery of listed threatened species and ecological communities, conservation advices and where required, recovery plans are made or adopted in accordance with Part 13 of the EPBC Act. Conservation advices provide guidance at the time of listing on known threats and priority recovery actions that can be undertaken at a local and regional level. Recovery plans describe key threats and identify specific recovery actions that can be undertaken to enable recovery activities to occur within a planned and logical national framework. Information about recovery plans is available on the department’s website at: http://www.environment.gov.au/biodiversity/threatened/recovery.html.

Consultation document for Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo)

Adult Glossy Black-Cockatoo © Copyright, Brian Furby Collection Conservation status Calyptorhynchus lathami lathami is being assessed by the Threatened Species Scientific Committee to be eligible for listing under the EPBC Act. The Committee’s assessment is at Attachment A. The Committee preliminary assessment of the subspecies’ eligibility against each of the listing criteria is:

• Criterion 1: A2bc+3b+4bc: Vulnerable • Criterion 2: Not eligible • Criterion 3: C2a(ii): Vulnerable • Criterion 4: Not eligible • Criterion 5: Insufficient data The main factors that appear to make the subspecies eligible for listing in the Vulnerable category are declining population trend, extent of occurrence (EOO), area of occupancy (AOO), and the small population size. The subspecies has undergone a substantial reduction (30–50 percent) in the last three generations (35.7 years for this assessment; Cameron et al. 2021). This

Threatened Species Scientific Committee 4 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document reduction in population was mostly caused by the 2019/2020 bushfires. Both EOO and AOO are contracting, they are estimated as 470,000 km2 and 40,000 km2, respectively (Cameron et al. 2021). Furthermore, the estimated total number of mature individuals is 7500, with a substantial declining rate (Cameron et al. 2021).

Cameron et al. (2021) estimate that 34 percent of the AOO for the subspecies was burnt. An analysis done by the National Environmental Science Program (NESP) Threatened Species Recovery Hub shows that a large proportion of the range of South-eastern Glossy Black- Cockatoo was affected by the 2019/2020 fires: 10 percent was burnt in high to very high severity fire, and a further 15 percent was burnt in low to moderate severity fire (Legge et al. 2021). A structured expert elicitation process was used to estimate the proportional population change for this subspecies from pre-fire levels to immediately after the fire and then out to three generations after the fire, when exposed to fires of varying severity. These results, combined with the spatial analyses of fire overlap, suggest that one year after the fire, the subspecies has experienced an overall decline of 15 percent from pre-fire levels, but that the decline could be as large as 32 percent (bound of 80 percent confidence limits). After three generations, the estimate for the overall population decline relative to the pre-fire population is predicted to be 22 percent, but potentially as much as 46 percent (bound of 80 percent confidence limit) (Legge et al. 2021). For comparison, experts also estimated the population change over time in the absence of fire; by three generations, the overall population of South-eastern Glossy Black- Cockatoo after the fire was estimated to be 5 percent lower than it would have been, had the 2019/2020 fire not occurred (Legge et al. 2021).

Species can also be listed as threatened under state and territory legislation. For information on the current listing status of this species under relevant state or territory legislation, see the Species Profile and Threat Database. Species information Taxonomy Conventionally accepted as Calyptorhynchus lathami lathami (Temminck, 1807).

One of three recognised subspecies. C. l. halmaturinus restricted to Kangaroo Island, is Endangered. C. l. erebus found in central Queensland is Least Concern.

Description The smallest of the black cockatoos (Calyptorhynchus spp.), with a body length of around 48 cm and weight of 420 g. Plumage mostly dull black, with a blackish-brown head, an inconspicuous crest and a broad bulbous bill. Adult males have bright red panels in the tail. Adult females have yellowish-red panels in the tail, and variable yellow patches on their heads. Juveniles are similar to adult females but with spotted pale-yellow patches on their heads, lower breast, belly and flanks, and barred undertail (Higgins 1999; Menkhorst et al. 2017).

The three subspecies have identical plumage and differ mainly in size and shape of their bills. C. l. lathami have moderate sized bills in comparison to a disproportionately large bill in C. l. halmaturinus, and C. l. erebus exhibit disproportionately small bills (Schodde et al. 1993; Higgins 1999).

Distribution South-eastern Glossy Black-Cockatoos are uncommon but widespread. They can be found from Mitchell, Queensland, through eastern to Mallacoota, Victoria (Map 1). Their distribution is continuous through the forested parts of the Great Dividing Range but becomes scattered more inland, to as far west as the Riverina in New South Wales (Higgins 1999; Garnett et al. 2011).

Cameron et al. (2021) estimated that their extent of occurrence (EOO) is 470,000 km2 and their area of occupancy (AOO) is 40,000 km2. The number of mature individuals was estimated to be 7,500 with a declining trend. Birds in the Riverina region were previously thought to be isolated from the main population (Garnett et al. 2011), however, they are now considered to be connected to the main population (Cameron et al. 2021).

Cultural and community significance Like other black cockatoos, the South-eastern Glossy Black-Cockatoo has a high public profile. The range of the subspecies occur through numerous Traditional Owner groups, including the lands of at least the following Indigenous Peoples: Anaiwan, Arakwal, , Barrumgum, Bidawal, , , Bundjalung, Butchulla, Darkinjung, Dharawal, Dharug, Dhudhuroa, Dunghutti, Euahlayi, , Githabul, , Gunaikurnai, Gundungurra, Jarowair, , Kabi Kabi, Kamilaroi, Mandandangi, , , Nindi‐Ngudjam Ngarigu Monero, Quandamooka, Turrbal, Waka Waka, Walgal, Warrabinga, Waveroo, , Wodi Wodi, , , Yaegl, Yugara, Yugambeh, and . There is currently

Threatened Species Scientific Committee 6 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document no known cultural significance of the South-eastern Glossy Black-Cockatoo, however further research into the subject area may benefit conservation initiatives by providing insights about traditional land management.

Relevant biology and ecology The species usually occurs in pairs or in groups of three (made up of a breeding pair and their offspring), in woodlands (Higgins 1999; Garnett et al. 2011). South-eastern Glossy Black- Cockatoos feed almost exclusively on the seeds of She-oaks (Allocasuarina spp. and Casuarina spp.), usually relying on one or two species within a region (Higgins 1999). This preference may explain the patchy distribution of the subspecies in parts of its range. They extract the seeds from closed cones, leaving characteristic feeding litter under the feeding trees (Clout 1989). South-eastern Glossy Black-Cockatoos may spend up to 88 percent of their day foraging and feeding, suggesting that the rate of intake is likely to be critical (Clout 1989). They show preferences to particular feeding trees, with the nutritional value of trees being the main driver of preference (Clout 1989; Crowley & Garnett 2001; Cameron & Cunningham 2006; North et al. 2020).

South-eastern Glossy Black-Cockatoos are hollow nesters, utilising large hollows in both living and dead eucalypt trees (Higgins 1999). They have a clutch size of one, and eggs are incubated by the female parent only. Once hatched, the nestling is brooded and fed by the female only. Males are present throughout incubation and nestling period to feed the females. Fledglings becomes independent after around three months (Higgins 1999). More detailed studies have been conducted on the Endangered Kangaroo Island subspecies (C. l. halmaturinus), which is likely to have similar nesting habits as C. l. lathami (e.g., Garnett et al. 1999). They have an estimated generation length of 11.9 years (Bird et al. 2020).

The movement patterns and ranging behaviour of the South-eastern Glossy Black-Cockatoo are poorly understood (Glossy Black Conservancy 2010). It has been suggested that they are seasonal migrants in south-east Queensland, likely as a response to changing of resource availability or breeding requirements (Stock & Wild 2005). Cameron (2005) observed a correlation between group size and environmental conditions, where larger foraging groups were observed when food resources were limited (i.e., during drought periods). However, further research is required to understand the subspecies in more detail.

Habitat critical to the survival Foraging habitat South-eastern Glossy Black-Cockatoos rely on nine species of She-oaks (Allocasuarina spp. and Casuarina spp.) for feeding (Chapman 2007), with species used varying depending on the region. Birds often only feed on one or two species in one region (Higgins 1999). In south-east Queensland and north-east New South Wales, they show preference for Black She-oak (A. littoralis) and Forest She-oak (A. torulosa), although there are also records of them feeding on Coastal She-oak (C. equisetifolia), and to a lesser extent River She-oak (C. cunninghamiana) and Swamp She-oak (C. glauca) during limited times of the year. On the islands of Moreton Bay and coastal lowlands, they seem to favour the Black She-oak, whereas Forest She-oak is the preferred species along mountain ridges and slopes (Glossy Black Conservancy 2010). In the Australian Capital Territory region their food trees are mostly restricted to Drooping She-oak (A. verticillate) (ACT Government 2013).

Threatened Species Scientific Committee 7 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

Breeding habitat Cameron (2006b) found that in central New South Wales, the majority of the nesting hollows were in Narrowed-leaved Ironbark (Eucalyptus crebra; 74 percent), other species of trees used were the Blue-leaved Ironbark (E. nubila; 16 percent) and Blakely's Red Gum (E. blakelyi; 10 percent). As a guide, potential nest hollows for the subspecies have the following traits (Cameron 2006b):

1) >8 m above ground; 2) Located in branches >30 cm in diameter; 3) Branch or stem no more than 45o from vertical; and 4) Minimum entrance diameter of >15 cm. Further research is needed to expand our knowledge on the nesting habits and habitat of the subspecies (i.e., nest tree species used in other regions of the subspecies range). Additionally, the Kangaroo Island subspecies (C. l. halmaturinus), may fly up to 14 km between feeding and nesting areas without adversely affecting breeding success, and most nests are within 1 km of their primary feed tree species, and 200 m of permanent water (Mooney & Pedler 2005).

Areas that are not currently occupied by the subspecies because they have been recently burnt but are capable of supporting cockatoo populations in the future, should also be considered as habitat critical for the survival of the South-eastern Glossy Black-Cockatoo.

Key considerations in environmental impact assessments Habitat critical to the survival of the South-eastern Glossy Black-Cockatoo occurs across a range of land tenures. Habitat critical to the survival of the subspecies should not be destroyed or modified. Actions that have indirect impacts on habitat critical to the survival should be minimised (e.g., noise and light pollution). Actions that compromise adult and juvenile survival should also be avoided, such as the introduction of new diseases, weeds or predators.

When considering habitat loss, alteration or significant impacts to habitat in any part of the South-eastern Glossy Black-Cockatoo’s range, including in areas where the species ‘may occur’, surveys for occupancy at the appropriate times of the year and identifying breeding sites and preferred foraging species remain an important tool in refining understanding of the area’s relative importance for the subspecies. Both recent survey data and historical records needs to be considered when assessing the relative importance of a region for the subspecies, as their seasonal movements is poorly understood, areas that constitute habitat critical to the survival might not have birds in any one given year.

Actions that remove habitat critical to the survival would interfere with the recovery of South- eastern Glossy Black-Cockatoos and reduce the area of occupancy of the subspecies. It is important to retain both breeding and foraging habitats described above. If removal of habitat critical to the survival cannot be avoided or mitigated, then an offset should be provided that benefits the subspecies in a similar timeframe to the impacts from the actions. Actions should not be assessed in isolation and consideration must be given to existing and future activities that may impact the subspecies to ensure conservation outcomes on a landscape scale are achieved.

Suitable offsets may include:

Threatened Species Scientific Committee 8 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

• Inclusion of unprotected areas of habitat critical to the survival in permanent nature reserves and provision of funding for the management of these areas. • Restoration of quality and extent of feeding and breeding habitat. • Restoration of native forest and woodlands adjacent to habitat critical to the survival to reduce edge effects. • Management of threats (see Threats) in and adjacent to habitat critical to the survival. • Other compensatory measures that will help address knowledge gaps to improve and maximise efficiency of the recovery of the species. No Critical Habitat as defined under section 207A of the EPBC Act has been identified or included in the Register of Critical Habitat.

Threats The most important threat faced by South-eastern Glossy Black-Cockatoo currently is habitat loss, degradation, and fragmentation. Historic land clearance was the main cause of decline in the past, leading to the loss of both feeding and breeding habitats. Wildfires cause further habitat loss and degradation. The subspecies was severely affected by the 2019/2020 bushfires, with a significant portion of their known range burnt. They were identified as a priority species post 2019/2020 bushfires, requiring urgent management interventions (Legge et al 2020). Currently, the distribution of the subspecies is patchy and fragmented throughout its range, which could likely become problematic in the near future, if subpopulations become isolated (e.g., Riverina birds). Grazing and invasive weeds are currently minor threats to the habitat of South-eastern Glossy Black-Cockatoos.

A major aspect of habitat loss is the loss of large hollow-bearing trees (i.e., their nesting sites). There has been increasing awareness of the importance of these hollows in the past 20 years for hollow-dependant species all around Australia as these large hollows take centuries to form. With limited hollow availability, competition for hollows also increases, this may also amplify otherwise minor threats such as nest predation and the transmission of diseases.

Climate change in Australia will impact this subspecies in a number of ways. With more extreme conditions (i.e., more fires, drought, and heatwaves), it is expected that there will be significant impact on their breeding and foraging habitats. Resource availability may also be affected by the changing climate.

Around 25 range percent of the overall distribution of the South-eastern Glossy Black-Cockatoo was burnt (Legge et al. 2021), and 34 percent of their area of occupancy (Cameron et al. 2021). Additionally, they were identified as a priority bird after the fires, requiring urgent management action in the next 12 months (Legge et al. 2020). Inappropriate fire regimes (i.e., too intense or too frequent) may significantly impact the subspecies’ feeding and breeding habitats (DEPI 2013). Burning of fire-sensitive species (e.g., A. littoralis and A. verticillata) may render feeding habitat unsuitable for a long time (Garnett & Crowley 2000; Garnett et al. 2011).

Some potential hollow competitors include Common Brushtail Possum, Galah (Eolophus roseicapillus), Little Corella (Cacatua sanguinea), Sulphur-crested Cockatoo (Cacatua galerita) and other South-eastern Glossy Black-Cockatoos (Mooney & Pedler 2005; Garnett et al. 2011). The loss of large hollow-bearing trees due to land clearance and deforestation is problematic as these large hollows take centuries to form in eucalypts (Gibbons & Lindenmayer 2002). Larger, older tree have a higher chance of bearing larger hollows (Gibbons et al. 2000), which is an important characteristic for C. lathami nest sites (see Relevant biology and ecology; and Garnett (1999) for hollow dimensions for Kangaroo Island subspecies). It is absolutely crucial to implement actions to prevent the loss of, and encourage the recruitment of, large hollow- bearing trees in order to minimise the lag effect and long-term risk of extinction of hollow-dependent species (Manning et al.

Threat Status and severity a Evidence 2013; Le Roux et al. 2014) like the South- eastern Glossy Black-Cockatoo. Nest boxes and artificial hollows are becoming an increasingly common management intervention to minimise the impacts of loss of nest sites for hollow nesters (Griffith et al. 2008; Rueegger 2017; Fay et al. 2019). However, for birds with specific hollow- dimension preferences, such as South-eastern Glossy Black-Cockatoos, more research is needed to tailor artificial nest box programs to the subspecies needs. This is important as studies have shown that simply setting up nest boxes mostly only attracted pest species rather than targeted threatened species (Grarock et al. 2013; Lindenmayer et al. 2016, 2017). Furthermore, artificial nest sites cannot completely replicate resources that large, hollow-bearing trees provide (Le Roux et al. 2016). Climate change Increased likelihood of • Status: current & future Average temperatures in Australia have extreme events (i.e., fire, • Confidence: known increased by just over 1 degree Celsius in the heatwave, and drought) past century (BOM & CSIRO 2020), and • Consequence: severe globally it is expected to rise up to another 2 • Trend: increasing degrees Celsius by 2050 (IPCC 2018).

Each threat has been described in Table 1 in terms of the extent that it is operating on the species. The risk matrix (Table 3) provides a visual depiction of the level of risk being imposed by a threat and supports the prioritisation of subsequent management and conservation actions. In preparing a risk matrix, several factors have been taken into consideration, they are: the life stage they affect; the duration of the impact; and the efficacy of current management regimes, assuming that management will continue to be applied appropriately (Table 2). The risk matrix and ranking of threats has been developed in consultation with list experts/community consultation and in-house expertise using available literature.

For those threats with an unknown or low risk outcome it may be more appropriate to identify further research or maintain a watching brief. Conservation and recovery actions Primary conservation outcome Long-term objectives (10+ years) • The subspecies’ population is stable, such that it no longer qualifies for listing as threatened under the EPBC Act listing criteria.

Threatened Species Scientific Committee 14 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

Short-term objectives (5-10 years) • Enhance extent and quality of habitat. Conservation and management priorities Land clearance and habitat fragmentation • Protect and enhance quality of known suitable habitat (both breeding and foraging) for South-eastern Glossy Black-Cockatoo. • Establish buffer zones (e.g., 1 km) of native forests or woodlands around important nesting areas to minimise incursions by competitors. Wildfire and inappropriate fire regimes • Develop a site-based fire management strategy (for both prescribed burning and fire suppression activities) with local authorities which considers the ecological needs of the subspecies. • Protect unburnt areas within or adjacent to recently burnt ground that may provide refuge areas. Grazing and invasive weeds • Consult with local authorities to determine the appropriate methods and the effectiveness of weed control and introduced herbivore management, and implement recommendations. Competition for nest hollows • Identify sites where hollows are limiting and develop and implement management strategies with local authorities and potentially the local community. Illegal bird and egg collection • Liaise with local authorities and continue to monitor for cases of illegal collection. Stakeholder engagement/community engagement • Raise the profile of the subspecies and its important habitats with landholders and generate awareness of impacts of inappropriate grazing regimes. • Raise awareness with the public and encourage submission of sightings to publicly available platforms (e.g. Atlas of Living Australia). • Raise awareness with landholders and the public on the importance of large hollow-bearing trees. Survey and monitoring priorities • Assess the impact of 2019/2020 bushfires on the subspecies and their habitat. • Monitor population trends at key sites throughout the distribution, in order to track overall population trends, document the effectiveness of management actions, and identify sites requiring further management action. • Monitor bushfire-affected areas to assess the impact of wildfire on the subspecies and their habitats.

Threatened Species Scientific Committee 15 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

• Monitor for cases of PBFD. If active, work with local authorities and develop site-based management strategies. Information and research priorities • Improve understanding of population structure across range, patterns of dispersal and connectivity across subpopulations, in order to design management to retain and support landscape connectivity. • Improve knowledge of the impact of wildfire on the subspecies and their habitat, and their ability to re-colonise recently burnt areas. • Increase knowledge of their feeding and breeding ecology (e.g., the reliance on particular trees species for feeding and as nest sites in different regions throughout the distribution of their range) and incorporate new knowledge into management. • Conduct further research and design a tailored nest box/artificial hollow program for the subspecies. • Use climate modelling techniques to investigate the potential impact of climate change on the subspecies, habitats critical for survival, and the availability of key resources. • Conduct further research to examine the competition with other species (in particular introduced species), and the impacts on South-eastern Glossy Black-Cockatoo. • Undertake further research to determine the level of threat posed by feral predators. Recovery plan decision A decision about whether there should be a recovery plan for this species has not yet been determined. The purpose of this consultation document is to elicit additional information to help inform this decision.

Established under the Environment Protection and Biodiversity Conservation Act 1999

The Threatened Species Scientific Committee finalised this assessment on DD Month Year. Attachment A: Listing Assessment for Calyptorhynchus lathami lathami Reason for assessment This assessment follows prioritisation of a nomination from the TSSC.

Assessment of eligibility for listing This assessment uses the criteria set out in the EPBC Regulations. The thresholds used correspond with those in the IUCN Red List criteria except where noted in criterion 4, sub- criterion D2. The IUCN criteria are used by Australian jurisdictions to achieve consistent listing assessments through the Common Assessment Method (CAM).

Key assessment parameters Table 4 includes the key assessment parameters used in the assessment of eligibility for listing against the criteria.

Criterion 1 evidence Eligible under Criterion 1 A2bc+3b+4bc for listing as Vulnerable

South-eastern Glossy Black-Cockatoo occur from Bundaberg in Queensland through eastern New South Wales to eastern Gippsland in Victoria. They have a continuous distribution through the forested parts of the Great Dividing Range but are more scattered inland where thy occur as far west as the Riverina and Pilliga Scrub in New South Wales, and St George in Queensland (Cameron et al. 2021).

The subspecies has been identified as a priority bird after the 2019/2020 bushfires, requiring urgent management interventions (Legge et al. 2020); Over 30 percent of the subspecies AOO was burnt (Todd & Maurer 2020; Cameron et al. 2021). Both the EOO and AOO are contracting, and a population decline of greater than 30 percent has been estimated (Cameron et al. 2021).

Trend data derived from surveys up to 2019 are not consistent and vary greatly between regions. Reporting rates from 500 m radius area searches across their range from 1999 to 2019 showed a 59 percent decline of the population (Cameron et al. 2021). However, no significant change in reporting rates were detected between 1977 – 1981 and 1998 – 2001 (Barrett et al. 2002 cited in Cameron et al. 2021), and the 2 ha 20 minutes survey data from 1999 to 2019 was too variable to provide a reliable trend (Cameron et al. 2021). Annual Glossy Black Cockatoo birding day event held since 2010 across south eastern Queensland and far north eastern New South Wales showed that these populations are stable with no significant decline over from 2010 to 2017 (G Castley unpublished data cited in Cameron et al. 2021).

Threatened Species Scientific Committee 23 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

An analysis by a team from the National Environmental Science Program (NESP) Threatened Species Recovery Hub, using a structured expert elicitation process to estimate the proportional population change for this subspecies from pre-fire levels to immediately after the fire and then out to three generations after the fire, when exposed to fires of varying severity. These results, combined with the spatial analyses of fire overlap, suggest that one year after the fire, the subspecies has experienced an overall decline of 15 percent from pre-fire levels, but that the decline could be as large as 32 percent (bound of 80 percent confidence limits). After three generations, the estimate for the overall population decline relative to the pre-fire population is predicted to be 22 to 46 percent (bound of 80 percent confidence limit) (Legge et al. 2021). For comparison, experts also estimated the population change over time in the absence of fire; by three generations, the overall population of South-eastern Glossy Black-Cockatoo after the fire was estimated to be 5 percent lower than it would have been, had the 2019/2020 fire not occurred (Legge et al. 2021). These predictions assume no further extreme drought or extensive fire events, however such events are likely to reoccur over the assessment period of 35.7 years.

Therefore, the subspecies has presumably undergone a population decline of greater than 30 percent over three generations (35.7 years for this assessment), based on the expert panel estimates of 22 to 46 percent decline and the survey data, and the reduction and the cause of reduction has not ceased. Therefore, the subspecies has met the relevant elements of criterion 1 to make it eligible for listing as Vulnerable. However, the purpose of this consultation document is to elicit additional information to better understand the subspecies’ status. This conclusion should therefore be considered to be tentative at this stage, as it may be changed as a result of responses to this consultation process.

Criterion 2 Geographic distribution as indicators for either extent of occurrence AND/OR area of occupancy

– Critically Endangered Vulnerable Endangered Restricted Limited Very restricted

B1. Extent of occurrence (EOO) < 100 km2 < 5,000 km2 < 20,000 km2

B2. Area of occupancy (AOO) < 10 km2 < 500 km2 < 2,000 km2

(c) Extreme fluctuations in any of: (i) extent of occurrence; (ii) area of occupancy; (iii) number of locations or subpopulations; (iv) number of mature individuals

Criterion 2 evidence Not eligible

Threatened Species Scientific Committee 24 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document

The EOO and AOO for the subspecies are 470,000 km2 (range 447,000–493,500 km2) and 40,000 km2 (range 21000–80 000 km2), respectively (Cameron et al. 2021). The EOO is based on all observance records since 1990. The minimum AOO is the number of 2x2 km squares within which thy have been record since 1990, but given the remoteness of much of the distribution, the real AOO is assumed to be at least doubled (Cameron et al. 2021). Around 34 percent of the 1x1 km squares from which birds have been record since 1990 were burnt (G Ehmke unpublished data cited in Cameron et al. 2021), but this impact is not enough to reduce the AOO below the threshold for consideration as Vulnerable.

The data presented above appear to demonstrate the subspecies is not eligible for listing under this criterion. Although greatly impacted by the 2019/2020 bushfires, the EOO and AOO for the subspecies are not considered limited. However, the purpose of this consultation document is to elicit additional information to better understand the subspecies’ status. This conclusion should therefore be considered to be tentative at this state, as it may be changed as a result of responses to this consultation process.

Criterion 3 Population size and decline

– Critically Endangered Vulnerable Endangered Low Limited Very low

C2. An observed, estimated, projected or inferred continuing decline AND its geographic distribution is precarious for its survival based on at least 1 of the following 3 conditions:

(i) Number of mature individuals ≤ 50 ≤ 250 ≤ 1,000 in each subpopulation (a) (ii) % of mature individuals in one 90 – 100% 95 – 100% 100% subpopulation =

(b) Extreme fluctuations in the number of mature individuals

Criterion 3 evidence Eligible under Criterion 3 C2a(ii) for listing as Vulnerable

The estimated total number of mature individuals of this subspecies is limited at 7,500 (range 6,000–10,500) mature individuals. An estimated decline is ongoing at a substantial rate. Expert

Threatened Species Scientific Committee 25 Calyptorhynchus lathami lathami (South-eastern Glossy Black-Cockatoo) Consultation document predictions suggest a decline over three generations of at least 22 percent (Legge et al. 2021). Further, the geographic distribution is precarious for the survival of the subspecies as all the mature individuals are considered as one subpopulation.

The data presented above appear to demonstrate that the subspecies is eligible to be listed as Vulnerable under this criterion. However, the purpose of this consultation document is to elicit additional information to better understand the subspecies’ status. This conclusion should therefore be considered to be tentative at this stage, as it may be changed as a result of responses to this consultation process.

Criterion 4 Number of mature individuals

– Critically Endangered Endangered Vulnerable Extremely low Very Low Low

D. Number of mature individuals < 50 < 250 < 1,000

D2.1 Only applies to the Vulnerable category D2. Typically: area of Restricted area of occupancy or number occupancy < 20 km2 or - - of locations with a plausible future threat number of locations that could drive the species to critically ≤ 5 endangered or Extinct in a very short time

1 The IUCN Red List Criterion D allows for species to be listed as Vulnerable under Criterion D2. The corresponding Criterion 4 in the EPBC Regulations does not currently include the provision for listing a species under D2. As such, a species cannot currently be listed under the EPBC Act under Criterion D2 only. However, assessments may include information relevant to D2. This information will not be considered by the Committee in making its recommendation of the species’ eligibility for listing under the EPBC Act, but may assist other jurisdictions to adopt the assessment outcome under the common assessment method. Criterion 4 evidence Not eligible

The total population size for the subspecies is estimated to be around 7,500 mature individuals (range 6,000–10,500). This estimation is based on that the AOO is twice that recorded, a density of one mature bird per 200 ha of ideal habitat (Cameron 2009), that 50 percent of the occupied grid cells include ideal habitat, and that the 2019/2020 bushfires rendered 30 percent of the habitat unsuitable for cockatoos for at least 10 years (Cameron et al. 2021).

The data presented above appear to demonstrate the subspecies is not eligible for listing under this criterion, However, the purpose of this consultation document is to elicit additional information to better understand the subspecies’ status. This conclusion should therefore be considered to be tentative at this stage, as it may be changed as a result of response to this consultation process.

Criterion 5 evidence Insufficient data to determine eligibility

Population viability analysis appears not to have been undertaken, and therefore there is insufficient data to demonstrate if the subspecies is eligible for listing under this criterion. However, the purpose of this consultation document is to elicit additional information to better understand the subspecies’ status. This conclusion should therefore be considered to be tentative at this stage, as it may be changed as a result of responses to this consultation process.

Adequacy of survey Although there is sufficient evidence to support the assessment, survey results have been inconsistent, and long-term regional monitoring is lacking for the subspecies. A standardised, range-wide, long-term monitoring program would benefit any conservation planning for the South-eastern Glossy Black-Cockatoo.
