4 Introduction Symposia for practitioners working in the field of Carnaby s Black-Cockatoo conservation are important occasional events in the conservation calendar. They have been held in 2003 and 2008 to provide a forum in which practitioners could network and exchange thoughts and ideas. A 2010 event provided an open invitation opportunity for the broader community to hear practitioner s papers on black-cockatoo conservation issues and research. In February 2013, Western Australian State NRM funds allowed BirdLife Australia to organise a symposium and associated experts workshop for practitioners. This symposium, like those in 2003 and 2008, was supported by the Department of Environment and Conservation (DEC). The aim of the 2013 Symposium was to bring together professionals working to recover Carnaby s Black-Cockatoo to share current knowledge. A planning discussion with the Carnaby s Recovery Team indicated that the symposium would provide better value if it focussed on the top two or three threats to the species. As the Recovery Plan lists the most important threats as threats to breeding range and non-breeding range habitat, it was agreed that the symposium and the follow up practitioners workshop would focus on these threats. Invited symposium presenters included staff from government agencies, non-government organisations, researchers and the community. Presenters were asked to identify the threats to habitat in the breeding and non-breeding range, consider the most important recovery actions, and the monitoring and evaluation of those actions. They were also asked to consider the effectiveness of recovery actions. Presentations included policy and planning initiatives and onground actions and research addressing threats to habitat in the breeding and non-breeding range. Researcher Dr Denis Saunders delivered the keynote presentation, a background paper in which he described the trajectory of range retraction and decline for the species and called for more intensive work, greater collaboration and improved prioritisation of recovery actions. He also noted the changes over the last decade in the public profile of the cockatoo, and the number of agencies, organisations, groups and individuals involved in conservation. The symposium was followed by an experts workshop for a necessarily reduced number of participants. Symposium delegates were however asked to contribute their ideas and provide input through sticky notes on butchers paper around the walls of the symposium venue. Delegates were asked to consider four questions: the identification of critical habitats and key threats; the conservation actions most likely to deliver benefit to the species; the conservation outcomes to be measured/monitored; and how those outcomes might be measured. At least 110 people accepted invitations to attend the symposium. People or groups or researchers undertaking work not being presented at the symposium were provided with the opportunity to display posters describing their work. Eleven people and groups took up this opportunity. The symposium proceedings provide short summaries of most presentations and posters, including contact details of speakers and poster authors. Importantly, the proceedings entries also list those resources published papers, unpublished reports, data and other resources that researchers, practitioners and others may be willing to share with the broader conservation community. BirdLife Australia acknowledges and thanks the many presenters and poster authors whose work was represented at the symposium, the people who attended, and those people who provided input on the program development. We also acknowledge the Western Australian Government State NRM Office for the funding that supported this event, and DEC for additional resources. The excellent venue was also made available by DEC. To all, our thanks. 1

Each year, hundreds of these charismatic, high profile birds are traumatised or injured across their range and flow through the Centre with a view to release back into the wild or to take part in breeding programs and community education programs. The Centre provides a unique bird rescue service across the State whereby injured birds at bought to the Centre for rehabilitation. The rehabilitated birds are released back into the wild flocks and the permanently damaged birds are placed within a captive breeding for release program. The Centre is allied to Government agencies such as the Department of Environment and Conservation, Perth Zoo and BirdLife Australia. While the BCCC is not the only true specialist Black Cockatoo rescue, rehabilitation and release organisation in Australia, but it is by far the most successful in release and associated monitoring by satellite tracking and tagging of rehabilitated cockatoos (in partnership with Murdoch University and Perth Zoo).

Most of the early efforts of the Recovery Project were in the wheatbelt, where it established an understanding of the breeding range of the species, and identified some landholders with breeding Carnaby s Black-Cockatoo. Direction for the Recovery Project since then has primarily come from the Carnaby s Recovery Plan. Many of the Recovery Project s conservation outcomes relate to the management of priority habitat on private land. Specific recovery actions include protection known breeding and feeding sites, usually by fencing or excluding stock; revegetation with proteaceous species; controlling nest competitors; repairing damaged or unused hollows; and increasing hollow availability. At some breeding sites, habitat protection has been achieved through the brokering of voluntary management agreements and conservation covenants with landholders, as well as the development of management plans for individual properties. Approximately 2100 hectares of habitat on private property have been enhanced or managed to date through the Recovery Project this figure will more than double by the time two of the currently funded initiatives are completed in June This work complements that undertaken by DEC in managing the formal conservation estate. 7

11 The achievements of the Recovery Project are a result of successful engagement and working relationships developed with a landholders, Landcare and community groups, shires and local government, government agencies, particularly DEC, regional NRM bodies diverse range of stakeholders including individual and NGOs. A large number of volunteers, many non-birdlife Australia members, have also contributed to project activities.

The landscapes between these IBAs support breeding populations of Carnaby s Black-Cockatoo on private land, local government reserves and in the conservation estate. The project engages landholders, community members, shires and agencies to increase and manage native habitat and deliver landscapescale conservation outcomes across landscapes of the project region. Specifically the objectives are to: Manage 1500 ha of native habitat and vegetation to reduce critical threats to biodiversity and enhance the condition, connectivity and resilience of habitats and landscapes. Increase landscape scale conservation through 18 farmers adopting activities across 700ha that contribute to the ongoing conservation and protection of biodiversity. Progress to date includes: Engagement of local landholders, community members and shires with regard to issues affecting Carnaby s within the project area via networks, flyers, landholder information sheets, direct contact and attendence at Newdegate Field Days. Completion of a nesting survey within one breeding season at currently known breeding sites and identification of three new breeding sites. 10

14 Identification of priority breeding and feeding sites through a prioritisation and ranking process. Identification of the priority recovery actions required at known breeding sites as: o o o Competitor (galah) control; Fencing of breeding sites; Increase in feeding habitat through revegetation at sites where potential feeding habitat within 12km of each breeding site is low. Competitor control (galah) in 2012 on seven properties surrounding a high priority breeding resulting in 620 galahs being eradicated, equating to approximately 1500 hectares of remnant vegetation better managed for nest hollow competitors. It is proposed that this be repeated in the 2013 nesting season to ensure ongoing control. Resources Brief description Can this be shared with other groups/researchers? Currently available?

The project began in January 2012 and in its first year has trialled tail feather marking techniques on 20 released rehabilitated Carnaby s cockatoos. Of these, 11 were also fitted with satellite tracking devices. The markings and tracking devices have enabled reporting of sightings and assisted undertaking flock follows. The rehabilitated cockatoos have demonstrated a high survival rate during their first year since release. Preliminary data on roost site fidelity, foraging area used around roosts and seasonal movements has been obtained. Ultimately the results of the project will provide information that could be used to identify conservation strategies to promote long-term persistence, help assess the potential impacts of proposed development on the cockatoos and to make urban planning decisions that consider the needs of the cockatoos.

A case example is Carnaby s cockatoo (Calyptorhynchus latirostris) which over the last 60 years has seen a population decline associated with the loss of feeding habitat in non-breeding areas due to extensive land clearing for agriculture and urban development. To conserve the Carnaby s cockatoo informed decisions about future development need to consider the importance of each habitat site (known and potential). Understanding the availability of food resources in relation to the population size is critical for future planning and management of the species. This project is quantifying food resource availability of native Banksia species for Carnaby s cockatoo on the Swan Coastal Plain and to examine how threatening processes (e.g. fire, Phytophthora cinnamomi) influence the availability of these resources. Information will be used to determine the number of birds that current resources can support and to provide critical information to guide the future management and conservation of Carnaby s cockatoo when prioritising habitat for conservation and acquisition on the Swan Coastal Plain. 14

19 Dr Anna Le Souëf Project/Initiative/Research Details Project or initiative name Organisation or affiliation (if relevant Project leader(s) name and title address Other relevant team members, position & A tool for the age estimation of black cockatoos (Calyptorhynchus spp.) Murdoch University Dr Anna Le Souëf Research Fellow, Conservation Medicine Program College of Veterinary Medicine, School of Veterinary and Life Sciences a.lesouef@murdoch.edu.au Dr Kristin Warren and Dr Carly Holyoake Murdoch University; Dr Simone Vitali Perth Zoo Project duration (start and finish date) Project/initiative/research description, including objectives and results to date This poster presents the findings of a study (Le Souëf et al, in press) aimed to create an aging tool for black cockatoos using pentosidine analysis. Prior to this study it was not possible to estimate the age of black cockatoos past juvenile stages, however, recently age estimation of several avian species has been achieved using pentosidine measurement. Pentosidine, an advanced glycation end-product (AGE), accumulates in the skin of birds over time and can be used as a biomarker of aging (Iqbal et al. 1999). Skin samples were collected from 51 black cockatoos of known age from the genus Calyptorhynchus and analysed for pentosidine concentration using high performance liquid chromatography. The plot of Ps against age was found to have a curvilinear relationship with a significant statistical association (R 2 = 0.86). This study offers the most accurate (within approximately two years (Fallon 2009)) model of age prediction in these birds past juvenile stages. This age tool will be used in ongoing demographic research in the Black Cockatoo Health and Ecology project at Murdoch University. The method will enable the estimation of age of black cockatoos entering rehabilitation programs, providing valuable data on the life histories of injured and debilitated wild birds. It is also being used to study the age demographics of wild populations, including cockatoos that were killed during a heat event in Hopetoun and Munglinup in 2010, providing further insight into the current status of these endangered birds. 16

At a State level, the DPC is working with the Department of Planning (DoP), the Department of Environment and Conservation (DEC), the Office of the Environmental Protection Authority (OEPA), the Department of Water (DOW) and the Department of Mines and Petroleum (DMP). More information on the Strategic Assessment of the Perth and Peel Regions is available on the following website: ult.aspx In July 2011, the Western Australian and the Commonwealth governments agreed to undertake a Strategic Assessment of the Perth and Peel regions. It is expected that drafts of the key policy and assessment documents will be released for a three month public comment period in mid to late The Strategic Assessment will assess the impact of future development proposed under Directions 2031 and Beyond and other state land use plans. The Strategic Assessment will consider all matters of national environmental significance (MNES) listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as well as factors normally considered under the Western Australian Environmental Protection Act Of particular significance will be the potential impact on Carnaby s cockatoo which requires a specific approach to incorporate a highly mobile and migratory species that utilises a large proportion of the remaining vegetation as feeding habitat. Approximately 112,700 ha of potential Carnaby s cockatoo feeding habitat remains in the Swan Coastal Plain part of the Perth-Peel Region (approximately 25% of the pre-european extent in this area). 51% (57,400 ha) of this is within DEC managed lands and a further 17% (19,600 ha) is in non-dec managed Regional Park or Bush Forever sites. Potential feeding habitat occurs in areas that have some form of development zoning. For example, there are 8,800 ha in areas zoned for urban or industrial purposes, much of which was zoned before Carnaby s cockatoo was listed as threatened. This existing zoned land poses the greatest challenge to providing conservation outcomes for Carnaby s cockatoo and other biodiversity values. The 26,000 ha of potential feeding habitat within rural zoned areas provides both a risk to some of that habitat, as well as providing opportunity for improved protection and management. Directions 2031 identified areas for investigation for possible future rezoning to urban and industrial. It should be possible to avoid impact on feeding habitat within these investigation areas as less than 2% of the 19

23 9,900 ha identified for possible urban and 14,000 ha as possible industrial area is potential feeding habitat. Removal of the 23,000 ha of Gnangara, Pinjar and Yanchep pine plantations is included in the Strategic Assessment. It is probable that pine plantations provide a greater amount of food per hectare than does banksia woodland (Will Stock s talk later in the symposium suggests four times the amount). Compared with the maximum area of native vegetation feeding habitat in the Strategic Assessment area that is identified for potential future development (approximately 15,000 ha) the loss of 23,000 ha of pine plantations is significant. To date 9,600 ha have been removed. The Strategic Assessment can achieve conservation outcomes for Carnaby s cockatoo by: Mitigation of impact (avoidance, minimisation, rectification, reduction and offsets) Implementation of active conservation programs or actions (such as recovery and research, and could consider actions across the species range) Relevant publications (please include full reference) The Strategic Assessment is making use of existing and available publications and data including those identified by other presenters.

We have a large bush property in the hills of Perth (metro area), that is frequented by Carnaby s. However, good nest hollows appear to be in short supply. To date we have installed 6 wooden nest boxes, 4 of which have been occupied, and the final 2 only recently installed. 2 male Carnaby s and one Redtail chick have fledged successfully, with fledging observed. The fledged (banded) Carnaby chicks were seen returning with their parents. 2 other Carnaby chicks suffered mishaps, and the egg in one nest failed to hatch. We are planning to install more nest boxes, and are looking forward to a good breading season in

Aims of the health component include: determining the epidemiology of potentially significant diseases; healthscreening rehabilitated cockatoos prior to release to ensure no introduction of key diseases to wild populations; determining blood reference range values for chicks; assessing nestling body condition; analysing blood parameters to check nutritional status of nestlings and to check for chronic stress indicators; investigating nest history, with viral prevalence in nests guiding management guidelines for artificial hollows/nests; and comparing all health findings across different geographical regions. An on-going aging study has used innovative pentosidine analyses to develop a black cockatoo age curve. This information allows us to age mature birds accurately for the first time, and thus to investigate concerns about the demographic structure of populations and potential declining recruitment. Finally, a satellite tracking program is developing the techniques to monitor black cockatoos during daily and seasonal movements over small and large spatial scales, and thereby identifying critical feeding and breeding areas. Our tracking program will use the optimal transmitter design developed based on previous work undertaken by Le Souef et al. (in press) and used in Christine Groom s current tracking study of rehabilitated Carnaby s cockatoos on the Swan Coastal Plain and our 2012 Proof of Concept tracking trial for Baudin s cockatoos. Both these studies demonstrate the success of our transmitter attachment protocols, and show that birds can be. 25

The study follows the work by Christine Groom, which is successfully demonstrating that Carnaby s cockatoos can be tracked using satellite transmitters, and a trial which involved attaching transmitter devices to captive black cockatoos of all three species (Le Souef et al. 2013, in press). Two rehabilitated adult female Baudin s cockatoos were anaesthetised and fitted with tail-mounted satellite trackers and released in Kelmscott in September Prior to release, both birds were health checked and flight tested to demonstrate fitness for release. The movements of the cockatoos were monitored according to Argos satellite transmissions, as well as ground truthing using flock sightings and reception of VHF signals from the satellite units using a radio telemetry antenna. According to their transmissions, the birds initially stayed in the Kelmscott area in close proximity to one another and other groups of Baudin s cockatoos in the area. However, after several days, one of the cockatoos flew south and joined a flock of Baudin s cockatoos migrating further south. Interestingly, during this migration, this bird returned to the Serpentine area from which she was originally found injured. This bird currently remains in the Beela area, 140km southeast of Perth, with other Baudin s cockatoos. The second cockatoo remained in the release area for several weeks before also moving south to Cardup, 33km southeast of Perth, where her transmitter was found two months later, still attached to the tail feathers which had possibly moulted out. 27
