1 of 91 18 1. 1. Executive summary 19 20 The Threat Abatement Plan for Infection of Amphibians with Chytrid Fungus Resulting in 21 Chytridiomycosis has been reviewed as required under the Environment Protection and 22 Biodiversity Conservation Act 1999. The actions that have been undertaken to abate the threat 23 from the disease as identified through the actions, goals and objectives of the threat abatement 24 plan have been assessed. 25 26 The review found that, while some of the actions had been undertaken and many partially 27 undertaken (for instance, there are now established protocols for field hygiene procedures), 28 the two goals of the threat abatement plan have largely not been achieved. That is, the further 29 spread of amphibian chytrid fungus within Australia has been slowed to some extent but it has 30 not been prevented from reaching almost all climatically suitable areas in Australia; and the 31 impact of infection with amphibian chytrid fungus on populations that are currently infected 32 has only been somewhat decreased. 33 34 Appropriate hygiene protocols have been developed and a national disease strategy will soon 35 be available. A number of different research projects have studied amphibian chytrid fungus 36 but there are still critical gaps in knowledge regarding the fungus, such as the apparent 37 immunity of some amphibian species and potential non-amphibian reservoir species. The 38 majority of the research work to date has been supported by funding from independent 39 sources and its completion and implementation requires further funding and resources. 40 41 The stakeholder working group identified the following priority actions still needing to be 42 undertaken: improved data collection to facilitate the identification of the population level of 43 threat in wild populations; establish a genome bank for the cryopreservation of threatened 44 species; continued research into the most effective methods of mitigating and suppressing the 45 disease in wild amphibian populations; and continued improvement in communication on the 46 disease. 47 48 The threat abatement plan identified the need to undertake coordinated national surveillance 49 of wild amphibian populations. This has not occurred to any extent, probably because of the 50 high level of resources that would be required to undertake such a task. The threat abatement 51 plan also identifies the need for identification and implementation of management actions for 52 amphibian chytrid in the listed threatened species. Some actions under this goal have been 53 undertaken through recovery planning for each species, although the degree to which the 54 disease is identified in the relevant recovery plans for each of the species ranges from the 55 chytrid fungus being identified as a threat to not being mentioned. The funding provided to 56 the listed threatened species through Caring for our Country was assessed and it has been 57 concluded that there is limited on-ground action supporting the review of this program to 58 directly abate the threat from amphibian chytrid fungus. Only two of the 17 project 59 summaries identified chytrid fungus as an action to be addressed. 60 61 The threat abatement plan is at a stage where eight of the 68 actions in the plan have been 62 completed and a further 39 actions are partially complete. It is concluded that there are still 63 actions outstanding that may be able to contribute to abating the threat but that the current 64 threat abatement plan requires a new direction to refocus the threat abatement actions. This 65 conclusion was supported by the stakeholders. Further, because the key threatening process of 66 Infection of Amphibians with Chytrid Fungus Resulting in Chytridiomycosis is still valid, 67 there remains a need for threat abatement. 68 Item 12.1.3

69 A separate options paper will explore the options available to the Minister to assist in abating 70 the key threatening process of infection of amphibians with chytrid fungus resulting in 71 chytridiomycosis. 72

77 5. 2. Purpose of review 78 6. 79 Under section 279 of the Environment Protection and Biodiversity Conservation Act 1999 80 (EPBC Act) the Minister must review each threat abatement plan at intervals of not longer 81 than five years. The Threat Abatement Plan for Infection of Amphibians with Chytrid Fungus 82 Resulting in Chytridiomycosis (the TAP) was made by the Minister in 2006. Under section 83 279 this plan is due for review. 84 85 Reviewing threat abatement plans, at least every five years, allows for an assessment of 86 whether the threat has been abated or, if not, what progress has been made towards abating 87 the threat. It is acknowledged that some key actions listed in threat abatement plans may take 88 longer than five years to achieve, such as improving re-introduction methodologies to 89 establish sustainable wild populations of threatened amphibian species. The review of a 90 threat abatement plan assesses progress and effectiveness of progress across all actions in the 91 threat abatement plan. It also considers progress towards threat abatement in associated ways, 92 such as work related to chytrid fungus done through recovery plans for specific species. 93 Finally it also considers if the threatened species are still being threatened by the key 94 threatening process. 95 96 The review of a threat abatement plan provides an opinion on whether a threat abatement plan 97 is still a feasible, effective and efficient means to abate a threat (s. 279A) and alternative 98 options for the Threatened Species Scientific Committee to consider and advise the Minister. 99

100 2.1 Review 101 The primary purpose of the review of the TAP is to assess the progress and effectiveness of 102 the TAP in reducing the impact of amphibian chytrid fungus on nationally listed amphibians 103 and preventing further amphibians from becoming threatened. 104 105 The Department of Sustainability, Environment, Water, Population and Communities (the 106 department) has undertaken the review in consultation with a working group comprised of 107 key stakeholders (researchers and state agency representatives), established to advise on 108 action to be undertaken under the TAP. 109

110 2.2 Approach 111 A meeting of the stakeholder working group in May 2012 reviewed the state of knowledge 112 and research around amphibian chytrid fungus. The department has drawn on this knowledge 113 as well as published scientific literature, grey literature, and reports to the Australian 114 Government to review each specific action in the threat abatement plan. 115 116 The key stakeholders (including the working group members) were invited in February 2012 117 to comment on the departmental assessment of progress and to provide comment on potential 118 future work that might be required to help abate the threat. Responses were received from 119 many stakeholders including representatives from each jurisdiction, non-government 120 organisations and key scientific researchers. 121 122

5 of 91 123 7. 3. Background 124 8. 125 ‘Infection of Amphibians with Chytrid Fungus Resulting in Chytridiomycosis’ was listed in 126 July 2002 as a key threatening species under the EPBC Act. The Minister determined under 127 section 270A of the EPBC Act that having a threat abatement plan was a feasible, effective 128 and efficient way to abate the impact of chytrid fungus on threatened Australian amphibians. 129 130 Australia’s native amphibians are threatened by a pathogenic fungus, Batrachochytrium 131 dendrobatidis (B. dendrobatidis), known either as the amphibian chytrid or the amphibian 132 chytrid fungus, which causes the infection known as chytridiomycosis. This infection affects 133 amphibians worldwide. This highly virulent fungal pathogen of amphibians is capable at the 134 minimum of causing sporadic deaths in some populations, and 100 per cent mortality in other 135 populations. Some species are resistant to mortality and serve as disease reservoirs and 136 carriers. 137 138 In Australia (see map at Attachment B), chytridiomycosis/B. dendrobatidis has been found in 139 all states and the Australian Capital Territory, but not in the Northern Territory. 140 Chytridiomycosis/B. dendrobatidis may have been introduced into Australia via the port of 141 Brisbane around 1978 and spread northward and southward. It did not appear to arrive in 142 Western Australia until 1985. The earliest records from South Australia and Tasmania are 143 from 1995 and 2004, respectively. There are some pockets of free areas within infected 144 regions due to the isolated nature of some amphibian populations. The disease does not 145 currently occur in Cape York Peninsula in Queensland and most of the World Heritage Area 146 in western Tasmania. A few isolated populations in NSW and Victoria are currently free of 147 infection. 148 149 Chytridiomycosis/B. dendrobatidis has caused the decline and extinction of several hundred 150 amphibian species globally. In Australia it has caused the extinction of at least four species 151 (all from Queensland), and the dramatic decline of at least 10 more. Many persisting species 152 remain at lower abundance and smaller distributions than pre-disease, some are continuing to 153 decline and significant mortality from chytridiomycosis/B. dendrobatidis is ongoing. 154 155 Currently there are no proven methods to control the disease in the wild. For currently 156 endangered frog species, emergency measures are needed to increase population sizes through 157 captive assurance colonies. As chytridiomycosis/B. dendrobatidis is now widely distributed in 158 Australia, control efforts should be aimed at protecting uninfected areas - this is the opposite 159 focus to standard emergency responses. Naive areas exist containing endemic frogs that are at 160 high risk. As strains vary in virulence, reducing the risk of spread between infected areas is 161 also important. Research to improve mitigation of the impact of the disease in infected wild 162 populations is ongoing and further work is urgently required. 163 164 Chytridiomycosis/B. dendrobatidis is listed as a notifiable disease in Australia’s National List 165 of Reportable Diseases of Aquatic Animals1 and by the World Organisation for Animal Health 166 (OIE, formerly Office International des Epizooties) in the Aquatic Animal Health Code.2 167

171 plans based on current knowledge can assist in reducing the impact of the disease on 172 threatened amphibian populations, particularly those presently in captive breeding programs 173 and for any future captive breeding of endangered species. 174 175 The threat abatement plan, therefore, had two goals: 176 9. to prevent amphibian populations or regions that are currently chytridiomycosis-free from 177 becoming infected by preventing further spread of the amphibian chytrid within Australia; 178 and 179 10. to decrease the impact of infection with the amphibian chytrid fungus on populations that 180 are currently infected. 181 182 183 11. 4. Assessment of actions undertaken against objectives 184 The threat abatement plan’s objectives were: 185 1. prevent the spread of B. dendrobatidis into areas where it may impact on threatened 186 amphibian species or may lead to amphibian species becoming threatened; 187 2. promote the recovery of nationally listed threatened amphibian species that are known or 188 perceived to be threatened by infection with B. dendrobatidis; 189 3. improve the effectiveness and efficiency of the management of infection with amphibian 190 chytrid through appropriate research and monitoring programmes; 191 4. share information with Australian, state and territory government management agencies, 192 researchers and other academics, landholders, relevant industries and the public about the 193 threat abatement plan’s actions and their outcomes; and 194 5. coordinate management activities effectively. 195 196 The implementation of the TAP was seeking to consolidate and coordinate the process of 197 managing chytrid fungus impacts on native amphibians, and acknowledged that control 198 programs will have to be ongoing and the costs of these could be considerable. As such, the 199 threat abatement plan established a framework to allow for the best possible use of available 200 resources. 201 202 Below is the assessment of progress against each of the specified actions. 203

217 4.1.1.2 Assessment of contribution to change of threat 218 The actions in this action group have been partially achieved through the development of a national disease strategy and various other strategies by 219 the states. However, one of the key actions, a coordinated national survey, has not been carried out. 220 Some of the actions under this action group are no longer relevant, as aside from through in few isolated areas, for example the Tasmanian 221 Wilderness World Heritage Area (TWWHA), it is no longer appropriate to prevent the large-scale spread of chytrid as the disease is now endemic in 222 most of the climatically suitable areas in Australia. Despite this, considerable effort has been expended to protect the few remaining isolated 223 uninfected amphibian populations. Various policy documents now exist in the jurisdictions that contain strategies to limit the risk of spreading 224 chytrid. However, there has been little coordination between the states in either policy development or surveying efforts for the presence and spread 225 of chytrid. 226 A national disease strategy has been prepared based on current best practices and the most recent research on chytrid fungus. Its possible inclusion as 227 a manual under AQUAVETPLAN is being explored.

that there are few proven treatments. Heat has been tested successfully on a few species but is not broadly applicable. The current widespread treatment protocol with itraconazole has not been adequately tested. Optimizing and validating itraconazole treatment is a priority. The JCU pathogenesis study (Voyles et al. 2009) showed that supplementing with electrolytes can improve clinical signs in sick frogs. Sam Young trialled this in combination with antifungals in three severely ill frogs and the success of this protocol demonstrates that this holds promise for intensive treatment of valuable individuals (Young et al. in press). Approval for scientific licences for research and management of frogs in NSW requires strict adherence to hygiene protocols. No releases to the wild are currently permitted in ACT except for threatened species reintroduction under licence. Captive populations and releases must conform to Amphibian Ark guidelines (Pessier and Mendelson 2010). The only releases so far have been captive-bred northern corroboree frogs in 2011, which were screened for chytrid fungus prior to release. Release site known to have chytrid present but

Frog breeding facilities, such as the Amphibian Research Centre (ARC), located at Werribee, and Zoos Victoria, apply their own standards. Any captive to wild releases of frogs requires animal ethics committee approval, Department of Sustainability and Environment (DSE) Translocation Evaluation Panel approval and a DSE research permit. In SA captive to wild releases of frogs require approval from animal ethics committee and research permit from the Department of Environment and Natural Resources (DENR). In Tas. one pilot assurance colony for the Tasmanian tree frog has been established at Bonorong Wildlife Park aiming to determine husbandry and captive breeding requirements for this species.

However, these standards for disease control will require ongoing implementation to be effective. It is also 239 essential to promote a greater awareness of the existence and purpose of these standards amongst the general public and industry as the level of 240 awareness of the risks posed by translocated amphibians is currently very low. 241 242 The other actions in this group were not achieved to any great extent. The incidence of accidental translocation of frogs over the last six years was 243 reported by most stakeholders to be relatively low, with the notable exception of Victoria. However, concerns remain that even a relatively small 244 number of accidental translocations of infected amphibians posed a very high risk to threatened populations. 245

The Hygiene protocols for the control of diseases in Australian 274 Frogs (Murray et al 2011c) report has been developed by leading researchers at James Cook University and made available on the departments’ 275 website. 276 277 This is a key action group that requires the implementation by the states and territories of the protocols that have been developed. Most jurisdictions 278 are implementing or advocating some form of hygiene protocol, but the variable approaches taken to date have resulted in the action being only 279 partially effective. It is also difficult to verify that protocols are adhered to in field situations. Further national coordination may be of benefit.

Some of the actions were found to be no longer relevant, in part 296 due to new knowledge about the disease and in part due to the almost complete spread of the disease to all climatically suitable areas throughout 297 Australia.

317 4.2.1.2 Assessment of contribution to change of threat 318 Some key components of this important action group and objective have been partially achieved: 319 Researchers at the James Cook University (Murray et al. 2011b,c) developed a captive husbandry manual that addresses disease control, but national 320 guidelines have not been established. Additionally, due to the large biological differences between amphibian species, quite often different 321 techniques and approaches to captive breeding are necessary. 322 Currently there is no mechanism for stakeholders to coordinate and share information on captive breeding of amphibians but the proposed 323 communication strategy outlined in Objective 4 would be expected to contribute to the future achievement of this goal. 324 Captive breeding and re-stocking programs have progressed with improved success. However, more work is required on understanding of the 325 interactions between chytrid and frog survival in reintroduction programs and also techniques to achieve self-sustaining populations in the wild need 326 to be developed. Most stakeholders see this is a high priority to ensure the short-term survival of some of the most threatened species. 327 328 Many other actions under this objective were not achieved. 329 Monitoring programs were identified by all stakeholders as critical for informing conservation programs for the preservation of threatened species. 330 However, in virtually all jurisdictions there are currently many threatened species about which little is known regarding their distribution, mainly due 331 to resource constraints. 332 There has been no cryopreservation of threatened amphibian species in Australia and no national approach to genome banking has been established. 333 334 4.2.2 Conclusion of assessment of contribution to change of threat from Objective 2 335 336 In conclusion, under Objective 2: Recovery of listed threatened species there has been important work undertaken to minimise the threat to and 337 improve the recovery of listed threatened amphibian species but there is still much to be done. Priorities include: coordinated monitoring and 338 surveillance programs; captive breeding and reintroduction protocols; and the establishment of a genome bank. The majority of the work to date has 339 been supported by funding from independent sources and its completion and implementation requires further funding and resources. When assessing 340 actions taken under this objective the conclusion is that the actions have made a very limited contribution to threat abatement. There has been no

38 of 91 Item 12.1.3

341 evidence to suggest an improvement in the status of any of the identified threatened amphibians. None of the threatened frog species listed at the 342 time of the making of the TAP in 2006 have decreased in their threatened status. However, four species have increased in their threatened status 343 since 2006, including one species being added to the threatened list. In many cases, there has been insufficient monitoring and evaluation of the 344 species to understand the population dynamics and there may also be other significant threats to those species, such as habitat loss, meaning that the 345 species has not had a chance to recover. It is also not possible to determine whether chytrid fungus is likely to become a key threatening process to 346 amphibians that are currently not threatened.

347 4.3 Objective 3: Research and monitoring 348 To improve the effectiveness and efficiency or the management of infection with amphibian chytrid through appropriate research and 349 monitoring programmes. 350 Performance indicators: 1. Standardised diagnostic tools are used to inform an understanding of the national distribution and prevalence of the 351 disease. 2. Management strategies are informed of emerging information provided through research. 352 353 The amphibian chytrid was first identified in 1998. While significant progress has been made in understanding the disease, its biology in the 354 environment is virtually unknown. This is a major obstacle to developing evidence-based control measures. Control strategies can be proposed with 355 our current knowledge, but the poor understanding of how B. dendrobatidis behaves in the environment needs to be remedied. Ensuring that field 356 experience and research are used to further improve management programs is an important element of this plan. Adaptive management approaches, 357 which experimentally test existing and new management techniques, will be encouraged. By measuring the effectiveness of different management 358 techniques in achieving the recovery of threatened species, we will improve our ability to combat the threat posed by infection with the amphibian 359 chytrid.

Approximately 70 per cent of samples from this species had inhibition based on subsequent testing with an internal positive control, which would have contributed to the low levels of Bd detected by the qPCR (Hines 2007). Hyatt et al. (2007) said that the maximum number of samples that could be pooled without lowering the sensitivity of the Taqman assay was five, which in essence could provide some cost efficiencies. However, they also reported an incidence of false negative in a pool of five field samples that returned a negative result, one low level (11 zoospore equivalents) positive was detected when samples were reanalysed individually. JCU suggested that it is possible to concentrate samples to overcome the dilution effect of pooling samples, but no further information was provided. They also cited Garland et al.

371 4.3.1.2 Assessment of contribution to change of threat 372 Some important progress has been made in the development of diagnostic tools for amphibian chytrid fungus, but limited funding and resources are 373 restricting the achievement of many of the actions in this group and under the research and monitoring objective. For example, the Australian 374 Animal Health Laboratory (AAHL) was identified by the OIE as the international (and thus national) quality accredited laboratory dedicated to the 375 diagnosis of chytridiomycosis. But due to severe financial constraints the AAHL has been unable to continue with their chytrid research or 376 diagnostic work.

It is critically important for the 377 national management of chytrid into the future that funding be provided for chytrid diagnostic work at AAHL or an alternative laboratory(ies) be 378 accredited and funded to continue this work. 379

The majority of this work has been supported by funding from independent sources and its completion and 391 implementation requires further commitment of funds. 392 393 Overall this action group has been effective in answering many biological questions about chytrid. However, questions still remain unanswered 394 regarding the transmission, reservoirs and possible vectors of the disease, and these require further research to be answered. In addition, the atypical 395 disease pattern being observed in frog species in WA requires further investigation. 396 Regarding accidental translocation, currently no widespread systematic approaches appear to be in place, thus there is no way of really knowing 397 what or how many individual translocations have occurred, how effective the jurisdictional strategies are, and thus how effective this action has 398 been. 399

431 4.3.4.2 Assessment of contribution to change of threat 432 Parts of this action group were achieved, for example historical survey results were published in 2010 by James Cook University and work 433 undertaken in NSW and ACT indicates that chytrid was the major cause of the drastic decline of the corroboree frog species. Good work has also 434 been undertaken on improving re-introduction methodologies to establish sustainable wild populations of threatened amphibian species but it is too 435 soon to make an assessment on the outcome. 436 437 Other actions in this group were only partially achieved as only limited work has been performed, such as the evaluation of hygiene protocols and 438 the development of treatment protocols. Much more work is also required to understand the mechanism underlying individual resistance to chytrid, 439 the effect across species and its role in allowing populations in the wild to persist and even recover from the impact of chytrid. For this to occur, 440 ongoing funding is needed. 441 442 4.3.5 Conclusion of assessment of contribution to change of threat from Objective 3 443 444 Some important progress has been made in achieving the goals of Objective 3: Research and monitoring through the development of diagnostic tools 445 and management techniques for species that continue to decline due to chytrid fungus, but limited funding and resources are restricting the 446 achievement of many of the actions under this objective. For example, it is critically important for the national management of chytrid into the 447 future that Australia have well resourced national quality accredited diagnostic laboratory facility(ies) such as AAHL.

463 4.4.1.2 Assessment of contribution to change of threat

464 The key stakeholder group, which met in May 2012, indicated there is a sufficient level of cooperation but insufficient communication between the 465 range of interested groups. The stakeholders commented that reporting and information sharing is not undertaken in any formal or structured 466 way and due to lack of resources the information on the website specified in Actions 4.1.6 and 4.1.7 (the Amphibian Disease Home Page) has 467 not been updated since 2008, therefore it does not provide a good picture of the current situation. 468 The stakeholders considered this issue at the workshop in May 2012 and developed a strategy to progress this objective and facilitate improved 469 communication. The Australian Registry of Wildlife Health has an existing public website which could be utilised to provide publicly available 470 information. The current content of the Amphibian Disease Home Page would be moved across to this site and updated as required. The Australian 471 Biosecurity Intelligence Network offered to host a secure community space on their website for stakeholders and researchers to utilise to share 472 information and establish communication pathways. The Australian Wildlife Health Network provides a way of reporting diseases listed as key 473 threatening processes and at the workshop in May 2012 they offered a strategy to circulate relevant information to stakeholders via a “chytrid 474 digest”. This strategy is an excellent step forward with this objective but will rely on all contributors to the network posting information as it is 475 produced. 476

62 of 91 Item 12.1.3

477 There is a reasonable level of awareness of chytridiomycosis in the general community in Australia. Some public information is available through 478 factsheets and internet websites (examples at Attachment A) but should be coordinated, kept up to date and made more easily accessible. It is also 479 clear that some aspects of the disease are still poorly understood by members of the public. Therefore, continuing education is important. 480 481 4.4.5 Conclusion of assessment of contribution to change of threat from Objective 4 482 483 The review concludes that overall there has been limited contribution to the change of threat through the actions under Objective 4: Stakeholder 484 communication on TAP objectives.

504 4.5.1.2 Assessment of contribution to change of threat 505 Twenty-nine frog species are currently listed as threatened under the EPBC Act. Four species are listed as extinct. Of the 29 listed threatened 506 species, only 20 of the species have recovery plans. Within these 20 recovery plans, 15 plans mention chytrid fungus as a contributing factor in the 507 decline of frog populations, whilst five recovery plans do not mention chytrid fungus in the plan at all. All of the plans addressed other possible 508 threats which contribute to frog population decline. 509

64 of 91 Item 12.1.3

510 The 15 species that have recovery plans mentioning the potential threat from chytrid fungus are the armoured mistfrog, mountain mistfrog, Kroombit 511 Tinker Frog, waterfall frog, common mistfrog, spotted tree frog, Fleay’s frog, giant barred frog, lace-eyed tree frog, Baw Baw frog, southern 512 corroboree frog, Eungella day frog, Tinkling frog, Wallum Sedge frog and the stuttering frog. Determining the degree of threat from chytrid fungus 513 has been identified as an action item in each of these recovery plans. It is also useful to know for what species chytrid fungus is not having a 514 threatening impact. For example, most recovery plans state that chytrid is a major cause for the decline in species population whilst some recovery 515 plans mentioned that chytrid fungus could be a potential threat but other factors posed a more likely threat, such as feral animals, UV-B radiation, 516 chemical pollutants, or the introduction of exotic fish and mammals. 517 518 While this review has been able to identify where researchers are concerned about the threat of the chytrid fungus to the threatened species through 519 actions identified in recovery plans, the actual action on the ground and abatement of the threat is much more difficult to measure. This may be in 520 part due to a lack of resources to undertake sufficient surveillance of all of the threatened species or a focus of recovery teams on other priorities 521 (e.g. habitat loss). It should be noted that the resources required undertaking comprehensive surveillance would be very expensive. 522 Recovery plans can provide a focus for recovery teams or community groups to seek funding for actions through government funding. Appendix C 523 provides details on funding provided through the Australian Government Caring for our Country program for the management of the 29 threatened 524 frog species identified in the TAP. Only two project summaries identify specific actions targeting the problem of chytrid fungus in the species.

525 4.5.2 Action group 5.2 – Use regional management plans 526 Regional management plans, agreed by governments and the community, set out the means for identifying and achieving a region’s natural resource 527 management targets. They detail catchment-wide activities including land and water management, biodiversity and agricultural practices.

535 4.5.2.2 Assessment of contribution to change of threat 536 Stakeholders report that regional and local management plans have in general failed to address the issue of chytrid fungus. Recovery plans for 537 individual threatened amphibian species have often included chytrid fungus as a risk factor when considering reintroduction to the wild as an option 538 in order to increase populations and species numbers. 539 540 The review considers that the objectives of this action group have not been achieved.

553 4.5.3.2 Assessment of contribution to change of threat 554 The objectives of this action group have not yet been met. However, a stakeholder working group consisting of a broad selection of people 555 representing all states and territories, from both state and federal government agencies, as well as leading researchers, was formed at the May 2012 556 workshop. It is proposed that this group will be called the National Chytrid Group and take on the role and responsibilities of the proposed 557 Amphibian Diseases Threat Abatement Committee. 558 559 The formation of this stakeholder working group has provided some progress towards the actions of this group being met in the future. The 560 Commonwealth would be expected to support this group and have an ongoing coordination role in the actions under this objective. 561 4.5.4 Conclusion of assessment of contribution to change of threat from Objective 5 562 563 In conclusion, this review has found that overall Objective 5: Coordination of management activities has achieved little towards a change of threat 564 since the TAP was made in 2006. Many of the actions under this objective require implementation at the regional and state level but coordination 565 efforts are needed at the national level.

These projects total $718,009. Two of the 592 projects specifically identify chytrid in their project summaries and the others include general 593 actions to assist in the recovery of the threatened species. This includes feral animal and 594 weed control, revegetation and other actions to improve water quality in wetlands etc. A 595 further seven projects that generally improve habitat for native Australian frogs have also 596 been funded, with a total value of $124,645. A summary of all of these projects is at 597 Attachment E. 598 599 The majority of funding specifically directed toward chytrid fungus research and development 600 has been obtained by universities through grants such as those provided by the Australian 601 Research Council. 602 603 A workshop of key stakeholders and experts held in May 2012 considered the issue of chytrid 604 fungus and the actions identified in the threat abatement plan. At that workshop the key 605 actions still to be undertaken were identified as: improved data collection to facilitate the 606 identification of the population level of threat in wild populations; a genome bank for the 607 cryopreservation of threatened species; continued research into the most effective methods of 608 mitigating and suppressing the disease in wild amphibian populations; and continued 609 improvement in communication on the disease. These actions will require significant funding 610 and resources to be achieved. 611 612

613 13. 6. Conclusions

614 6.1 Completion of TAP actions 615 This TAP comprises 68 actions listed under five objectives. Of these it is considered that 616 eight actions have been completed, 39 actions have been completed in part, and 21 actions not 617 completed. Where the actions have been identified as being completed in part, this is 618 typically because the action relates to something that needs to be done across all the 619 threatened species, all of the states or because only a portion of the research has been 620 undertaken to date.

621 6.2 TAP action contribution to goals and objectives 622 The implementation of actions in this TAP has occurred in varying degrees across all of the 623 objectives. 624 625 The first objective focuses on the prevention of pathogen spread. Some of the actions under 626 this objective were found to be no longer relevant, in part due to new knowledge about the 627 disease and in part due to the almost complete spread of the disease to all climatically suitable 628 areas throughout Australia. The stakeholders commented that at this point in time it would be 629 much more useful to change the focus of this objective from trying to contain the disease (the 630 opportunity to achieve this has passed) to suppressing and mitigating the effects of the disease 631 on threatened amphibian populations. However, some good work has been achieved under 632 this objective, such as the development of hygiene protocols and a national disease strategy. 633 634 The second objective focuses on recovery of listed threatened species. There has been 635 important work undertaken during the life of this TAP to minimise the threat to and improve 636 the recovery of listed threatened amphibian species, mainly through the development of 637 captive breeding programs, but there is still much to be done. Priorities to be addressed 638 include: coordinated monitoring and surveillance programs; captive breeding and 639 reintroduction protocols for individual species; and the establishment of a genome bank. The 640 majority of the work to date has been supported by funding from independent sources and its 641 completion and implementation requires further funding and resources. When assessing 642 actions taken under this objective the conclusion is that the actions have made a very limited 643 contribution to threat abatement. There is no evidence to suggest an improvement in the 644 status of any of the identified threatened amphibians. None of the threatened frog species 645 listed at the time of the making of the TAP in 2006 have decreased in their threatened status. 646 However, four species have increased in their threatened status since 2006, including one 647 species being added to the threatened list. In many cases, there has been insufficient 648 monitoring and evaluation of the species to understand the population dynamics and there 649 may also be other significant threats to those species, such as habitat loss, meaning that the 650 species has not had a chance to recover. It is also not possible to determine whether chytrid 651 fungus is likely to become a key threatening process to amphibians that are currently not 652 threatened. 653 654 The third objective focuses on the research and monitoring required to further increase our 655 knowledge of chytrid fungus. Overall the review concludes that we now understand more 656 about the disease, including through the development of diagnostic tools and management 657 techniques for species that continue to decline due to chytrid fungus, but limited funding and 658 resources are restricting the achievement of many of the actions under this objective. For 659 example, it is critically important for the national management of chytrid fungus into the 660 future that Australia have a national quality accredited laboratory facility(ies) such as AAHL. 661 Additional answers are needed regarding the transmission, reservoirs and possible vectors of 73 of 91 Item 12.1.3

662 the disease and also the apparent resistance that some individuals demonstrate. The 663 conclusion for this objective is that some progress has been made during the life of the TAP 664 but further action is critical. 665 666 The fourth objective of stakeholder communication has not been met. Stakeholders report that 667 reporting and information sharing is not undertaken in any formal or structured way and due 668 to lack of resources the information on the central website specified in the objective has not 669 been updated since 2008. However, during the review process the stakeholders met and 670 developed a potential communication strategy to progress this objective and facilitate 671 improved communication. This has the potential to provide a central website for public 672 information and also an essential conduit between all stakeholders. 673 674 The fifth objective focuses on coordination of management actions and strategies. The review 675 found that little has been achieved under this objective since the TAP was made in 2006. 676 Many of the actions under this objective require implementation at the regional and state level 677 but coordination efforts are needed at the national level.

678 6.3 TAP goals 679 The TAP has two goals of to prevent amphibian populations or regions that are currently 680 chytridiomycosis-free from becoming infected by preventing further spread of the amphibian 681 chytrid within Australia; and to decrease the impact of infection with the amphibian chytrid 682 fungus on populations that are currently infected. 683 684 While there has been progress made on some of the actions identified in the TAP, such as the 685 development of hygiene protocols, a rapid field test to detect the chytrid fungus and some 686 research undertaken into the disease, it cannot be concluded that either of the two goals have 687 been met. The amphibian chytrid fungus has spread to almost all of the climatically suitable 688 areas in Australia, aside from a few isolated areas, for example the TWWHA. There is no 689 evidence to suggest an improvement in the status of any of the identified threatened 690 amphibians. None of the threatened frog species listed at the time of the making of the TAP in 691 2006 have decreased in their threatened status. However, four species have increased in their 692 threatened status since 2006, including one species being added to the threatened list. In many 693 cases, there has been insufficient monitoring and evaluation of the species to understand the 694 population dynamics and there may also be other significant threats to those species, such as 695 habitat loss, meaning that the species has not had a chance to recover. 696 697 In conclusion, the assessment of the review, as to whether the TAP has abated the threat from 698 chytrid fungus to threatened amphibian species, is that the threat is still current and has not 699 abated.

700 6.4 Outstanding issues 701 The key outstanding actions required under the TAP are: improved data collection to facilitate 702 the identification of the population level of threat in wild populations; a genome bank for the 703 cryopreservation of threatened species; continued research into the most effective methods of 704 mitigating and suppressing the disease in wild amphibian populations; and improvement in 705 communication on the disease. These actions were identified by the key stakeholders during 706 the consultation phase of the review process. There are other actions that were also identified 707 as warranting attention. 708 709 On the research side there are still significant gaps in our knowledge about the virus 710 characteristics, apparent immunity of some frog species and populations, and transmission 74 of 91 Item 12.1.3

711 factors including host factors, environment factors, population dynamics and other species as 712 reservoirs of the virus. 713 714 A lack of funding is severely limiting the implementation of many threat abatement actions 715 required under the TAP. For example, it is critically important for the national management of 716 chytrid into the future that Australia has a well funded, fully resourced national quality 717 accredited laboratory facility(ies) such as AAHL. The coordination of management actions 718 and strategies is also required. 719 720 As for recovery planning there are still gaps for some species in knowing whether chytrid 721 fungus is a significant threat and, for other species, what the impact is on a population level 722 relative to other threats. Even for those species where chytrid has been identified as a threat, 723 there is insufficient on-ground action to counter the threat. 724 725 There is some limited communication and information exchange occurring on chytrid fungus. 726 However, the review identified that this has been very ad hoc, should be better coordinated 727 nationally and needs to be considered in the future management of chytrid fungus. There will 728 be an ongoing challenge to ensure good communication continues with many other issues 729 demanding the time of those people interested in abating the threat of chytrid fungus. 730

2011/2012 VIC This project aims to protect and enhance native habitat in the Lismore Landcare $17,830 VFF Farm Tree & Landcare Association Inc network area of the Victorian Volcanic Plains, including threatened species habitat CAG-720071-354 protection and enhancement for Corangamite water skink, growling grass frog (green and gold bell frog), striped legless lizard and brolga. Protective fencing of remnant native grassland vegetation, natural wetlands and stony barriers will enhance native habitat value by separating significant areas from more cultivated areas of farms. This project will also involve weed control and additional planting of indigenous species (where appropriate).

2011/2012 NSW This project will provide research results and extension to improve riparian condition Holbrook Landcare Group and habitat. The project will focus on threatened and endangered fish and amphibians, $20,000 CAG-719549-305 in the upper reaches of the Murray Darling Basin, target species are great bio indicators of healthy waterways. The project will add to existing local CSIRO research on the impact of revegetation work on remnant threatened woodlands and land based fauna. Information on the value of riparian plantings for aquatic ecosystems will add significantly to the landscape picture. Community engagement will reinforce the importance of fragile riparian ecosystems. The project will compliment a strategic fertiliser project to limit nutrient loss into the air and water 2011/2012 TAS The aim of this project is to improve bank and flood plain stability along a section of the lower South Esk River in Northern Tasmania to reduce sediment deposition CAG-729280-913 Northern Midlands Council downstream. Works will include planting native shrubs and trees, grasses and sedges. $13,620 Also filling and direct seeding strips along the banks which were scoured during recent successive floods. These works will in the long term support multiple outcomes of improved water quality (beneficial for all) and habitat value outcomes for species including the green and gold frog.

2010/2011 Noosa QLD The project will re‐establish habitat and biodiversity by weeding, revegetation and $9,995 Integrated rehabilitation in the Seaview Creek Reserve. This reserve is the only permanent water CAG10‐00780 Catchment and wildlife corridor, linking the Noosa National Park and dune foreshore for seven Association Inc kilometres. Weeds smothering the riparian vegetation inhibit wildlife passage and excess nutrients inhibit wallum froglet breeding. Due to the sensitive nature of the aquatic ecosystem, contractors and volunteers will weed by hand with minimal use of herbicides. Local provenance plants will be propagated, planted and maintained by volunteers and Landcare members. The community will be engaged through leaflets, word of mouth and meetings that address invasive weeds and their safe removal. The local council will remove rubbish and Noosa Water Watch will monitor water quality. Volunteers will maintain rehabilitated areas. Signage at the lower creek, boardwalk and beach shower will be installed to promote awareness of vulnerable acid frogs, wildlife,

Specific assistance sought to remove invasive weed species, lessening threat and increasing area for regeneration and planting.

2011/2012 TAS The project involves the creation of a natural wetland reserve in the area known currently as the Westbury Town Common. This community area is 12.13 hectares in CAG-720166-366 Westbury Working Together Inc. size and is located on the banks and flood plain of Quamby Brook. The area is largely cleared and grassed with minimal native vegetation. The Westbury Working Together Committee are seeking to re-establish the natural riparian vegetation and wetlands on the site and provide appropriate native habitat for birds, frogs and other animals as well as nurseries for fish. A diversity of habitats will result - floodplain grasslands, $10,950 billabongs, paperbark groves, shrubby forest elements, aquatic plantings and shade over the brook. Five threatened species will be protected

2011/2012 VIC This project protects and ensures the biodiversity of the tidal reach of the Spring Creek corridor, specifically along Bowman's Track. The preparatory work involves removal of CAG-722101-525 Torquay Landcare Group Inc weeds (serrated tussock, a Weed of National Significance) followed by ecological restoration and revegetation (including degraded areas) with indigenous species $19,800 (threatened Moonahs Ecological Vegetation Classes 858 endangered). The project evolves from a cultural survey and Ecological Vegetation Classes Assessment 2009 (potential gain of 1.66 hectares). Torquay Landcare Group will consult with the Surf Coast Shire. The project includes the installation of information and interpretation boards outlining the Indigenous history, local flora and fauna (including aquatic), weed control, the creek, adjacent frog ponds, and Who is John Bowman (Landcare legend).

2010/2011 Kimberley WA As the cane toad moves across Northern Australia, there has been misidentification of Toadbusters both cane toads and native frogs. This project will mitigate the impacts of cane toads CAG10‐00678 Inc on biodiversity through community engagement, including knowledge and skills on how to indentify cane toads and ways to control them. Information sessions will be held at local schools, in Indigenous communities, and at mine and construction sites. A $20,000 website will be developed, brochures will be distributed at tourist information centres and educational advertorials placed in local newspapers.

2010/201 Wilson Inlet WA The project will raise awareness and increase the appreciation of the unique Catchment biodiversity within the Wilson Inlet catchment by holding field days, workshops and CAG10‐00860 Committee Inc practical activities to engage the community. The local media will promote the activities to be undertaken. Awareness raising events will be held on relevant subjects such as sub sustainable farming planning, nutrient management, and fauna identification $19,400 including birds, frogs and nocturnal marsupials. Activities will also include feral animal and weed control. Community appreciation for the natural environment will be enhanced to encourage protection of remnant vegetation and the creation of wildlife corridors. The project will lead to increased productivity and sustainable agriculture while balancing the need for the protection and enhancement of biodiversity.

2011/2012 NT The proposal is to protect the biodiversity, particularly the reptiles, of the coastal fringe FrogWatch Nth Inc of Darwin from Vesteys Beach through to Lee Point by implementing a cane toad CAG-721755-501 management strategy, combined with other habitat management, to minimise the impact of cane toads in the area, and especially to minimise cane toad breeding. We $20,000 also propose to begin a monitoring process which will allow us to document the success of the management strategy, especially in relation to the endangered species Varanus panoptes. Observations show that we still have species present in these areas that have vanished from other locations in the top end. We believe this to be largely due to the success of the Community Cane Toad Control Initiative
