1. Introduction
This Threat Abatement Plan (TAP) establishes a national framework to guide and coordinate Australia’s response to Phytophthora cinnamomi. It identifies the research, management and other actions needed to ensure the long-term survival of native species and ecological communities at risk threatened by P. cinnamomi and replaces the threat abatement plan published in 2001 (Environment Australia 2001).
This plan should be read in conjunction with the publication, ‘Background document for the threat abatement plan for disease in natural ecosystems caused by Phytophthora cinnamomi’ (Commonwealth of Australia 2008). The background document provides information on the scope of the problem; characteristics, biology and distribution of the pathogen; impacts on the environment; and current management practices and measures.
1.1    Threat abatement plans
Under section 270 (A) of the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Australian Government develops TAPs and facilitates their implementation. The EPBC Act prescribes the process, content and consultation to be followed when making a TAP. An important part of the TAP is to ensure that knowledge of the threat and its management is disseminated to the community, land managers and land users.
 
Mitigating the threat of invasive species is not simply a matter of developing and applying better technical solutions. It also involves understanding and addressing social and economic factors, for example, through supporting the efforts of land managers, nurseries and plantation managers to manage and prevent P. cinnamomi infestation.
1.2    Threat abatement plan for Phytophthora cinnamomi
1.2.1   The threat
 
Healthy natural environments provide a range of direct and indirect benefits to the community, in addition to the intrinsic value of biodiversity. The disease caused by the introduced plant root pathogen, P. cinnamomi, threatens these values and benefits. This disease is often difficult to detect and its impact may be significant before it is detected. Depending upon environmental conditions and plant susceptibility, the pathogen can destroy vegetation communities. P. cinnamomi threatens several plant species with extinction.
 
While the pathogen directly threatens a range of plant species, the broader potential to impact on ecological communities and at a landscape level makes P. cinnamomi a very significant threat. This broader threat is not well understood, either in terms of environmental or economic impacts.
 
Infested areas are increasing in size throughout Australia. P. cinnamomi now infests hundreds of thousands of hectares of native vegetation in Western Australia, Victoria and Tasmania, and tens of thousands of hectares in South Australia. In far northern Queensland the extent of the threat is not known. The New South Wales Department of Primary Industry reports that the pathogen has been detected in soil samples from NSW national parks, as well as from nurseries and gardens. Concerns are increasing about the impact of P. cinnamomi in environmentally sensitive areas such as rainforests in Barrington Tops, Werrikimbe and Oxley Wild Rivers National Parks.
 
More information on the pathogen, the disease and its history in Australia can be found in the background document to this TAP (Commonwealth of Australia 2008).
 
The detrimental impacts of P. cinnamomi on biodiversity in Australia led to it being listed as a key threatening process under the EPBC Act. In 2001 the former Australian Government Department of Environment and Heritage published the first threat abatement plan: ‘Threat Abatement Plan for Dieback Caused by the Root-rot Fungus Phytophthora cinnamomi’.
 
P. cinnamomi is a threat to many native plant species (see the list at Appendix A).  This list is not comprehensive due to the previous high cost of detection of P. cinnamomi. Recent improvements in detection techniques (O’Brien, 2008) will enable more accurate and cost-effective detection of P. cinnamomi in infected soil and facilitate the further identification of vulnerable plant species. Although there has been a substantial amount of research on the effects of P. cinnamomi on vegetation, there has been little work investigating the indirect effects of the pathogen on faunal populations and communities (Cahill et al. 2008). Therefore non-plant species, which are affected because their food source or habitat is threatened, are not included in the listing
 
1.2.2       Managing the threat
There are currently no proven methods to eradicate P. cinnamomi from a site or to prevent active spread of the pathogen. As a result, the two major priorities of P. cinnamomi management are:
i)                    to mitigate the spread of P. cinnamomi to uninfested sites, and
ii)                   to mitigate the impact of P. cinnamomi at infested sites.
 
Humans can spread P. cinnamomi further and faster than any other infestation vector. The limited management options currently available focus on modifying human activities by restricting access to certain sites, and, when access is necessary, deploying and enforcing hygiene procedures to minimise the spread of P. cinnamomi in the landscape.  
 
Phosphite has been used to mitigate the impacts of P. cinnamomi on some vulnerable species at infested sites in Western Australia, but it requires further testing in other states and territories. Current detection and management options are described in the background document to this TAP (Commonwealth of Australia 2008) and in the ‘National Best Practice Guidelines’ (O’Gara et al. 2005).
 
Priority must be given to protecting and managing areas of high conservation value. These include areas within the climatic zones of P. cinnamomi susceptibility that:
·     contain threatened species or ecological communities susceptible to P. cinnamomi,
·     contain habitat susceptible to P. cinnamomi and critical to the survival of threatened fauna,
·     support high plant species endemicity,
·     support high species diversity for a type of vegetation,
·     support significant remnant vegetation, or
·     are large, ecologically intact and mostly undisturbed.
 
The TAP acknowledges the major gaps in knowledge that hamper current management. The TAP objectives progressively address priority setting, actions for land owners and managers, building understanding and capacity to perform these actions, and impact assessment. Further research into mechanisms of natural resistance, including the genetic basis of resistance, is targeted. An economic assessment of the scope and significance of the impact of P. cinnamomi on natural ecosystems is also a priority.
 
While the management of P. cinnamomi remains a challenge to land managers, progress was made under the original TAP in developing tools that will allow easier prioritisation of areas for management. Most importantly, a Risk Assessment Process has been developed that assesses the risk of P. cinnamomi to threatened species, ecological communities and areas, and ranking them as the basis for setting management priorities (CPSM 2005). While not yet field tested, the process is potentially suitable for national adoption.
1.2.3   The review process
In accordance with the requirements of the EPBC Act, the original TAP, ‘Dieback Caused by the Root-rot Fungus Phytophthora cinnamomi’ (EA 2001), was reviewed in 2006 (CPSM 2006).
 
The review surveyed a broad range of stakeholders and assessed a range of projects as part of the review. The Department funded seven projects between 2001 and 2005 to implement key actions. These projects included development of a risk assessment process and best practice management guidelines. The review comprehensively documented work that had been done across Australia, and identified projects that had been implemented and commissioned by the states and territories and on Commonwealth land. The review noted, for example, that the Sydney Harbour Federation Trust had adopted the approaches in the threat abatement plan into its management plans. 
 
While the review identified significant activity towards abating P. cinnamomi, it recommended stronger coordination of implementation under a revised threat abatement plan. The Australian Government will seek this stronger coordination under the AusBIOSEC national biosecurity institutional arrangements.
 
This TAP replaces the 2001 document. It incorporates the knowledge gained in the intervening years and has been modified in line with recommendations from the review. The title of the TAP has been modified from: ‘Threat Abatement Plan for Dieback Caused by the Root-rot Fungus Phytophthora cinnamomi’ to ‘Threat Abatement Plan for Disease in Natural Ecosystems Caused by Phytophthora cinnamomi’, to remove the terms ‘dieback’ and ‘root rot fungus’, which are technically incorrect and are used variably throughout Australia.
 
The TAP aims to guide the responsible use of public resources and the best outcomes for native species and ecological communities threatened by P. cinnamomi. It seeks to achieve these outcomes by recognising the existing opportunities and limitations, and ensuring that actions are flexible and can align with evolving management options as our understanding of P. cinnamomi improves through field experience and research.
1.2.4   Involvement of stakeholders
The success of this TAP will depend on a high level of cooperation between all key stakeholders, including landholders, land users, community groups, local government, state and territory conservation and resource management agencies, and the Australian Government and its agencies. It will be important that managers assess P. cinnamomi impacts and allocate adequate resources to achieving effective on-ground prevention and management at critical sites, improving the effectiveness of prevention programs, and measuring and assessing outcomes.
 
Many stakeholders, however, are unaware of the significance of P. cinnamomi and the ways it can be spread. Ongoing delivery of awareness and capacity building programs in natural resource management, at national, state and regional level, can make a significant contribution to national implementation of the TAP.
 
2. Goals and Actions of the Plan
 
The TAP has four long-term broad and overlapping goals for the Australia-wide management of
P. cinnamomi:
Goal 1:            Protection of species and ecological communities which are listed as threatened under the EPBC Act;
Goal 2:            Minimisation of the spread of P. cinnamomi infestation so that further species and ecological communities do not become threatened;
Goal 3:            Protection of areas of high conservation value; and
Goal 4:            Mitigation of the impacts of P. cinnamomi in currently infested areas of high conservation value.
 
These goals will be met through a suite of objectives and associated actions:
Objective 1:    To monitor sites of high conservation value under threat from P. cinnamomi;
Objective 2:    To develop and apply management actions that will minimise or mitigate the threat of P. cinnamomi;
Objective 3:    To strengthen training and education of land managers in the science and management of P. cinnamomi; and
Objective 4:    To assess P. cinnamomi impacts in Australia.
 
Each objective is accompanied by a set of actions which form the integrated national response necessary to achieve the objective. Criteria are provided against which achievement may be assessed for these objectives and their associated actions.
 
Each action has been assigned a priority of ‘medium’, ‘high’ or ‘very high’ and a timeframe for completion. Timeframes are categorised as short term (within three years) and medium term (within three to five years).
 
Objective 1:  To monitor sites of high conservation value under threat from P. cinnamomi
 
Management of the threat to sites of high conservation value will require a nationally consistent system of identifying and monitoring infested areas. This system should map the distribution of
P. cinnamomi, indicate presence of susceptible species and indicate sites of high conservation value (Actions 1.1 and 1.2).
 
Standard national methods for testing species susceptibility will allow the modelling of species susceptibility in the absence of confounding environmental or seasonal effects (Action 1.3). Observed variability in disease expression in the field can then be attributed to effects of the particular environment at the time of observation. A standard method of determining susceptibility would also improve the usefulness of the ‘National Risk Assessment Models’ developed by the Centre for Phytophthora Science and Management (CPSM 2005).

P.  cinnamomi; the distribution of susceptible species and ecological communities; and environmental variables such as rainfall, temperature, soil and nutrient types, are prepared, updated when infestations are discovered, and readily available.
Medium priority, medium term

Flora susceptibility
1.3 Develop a national model  for susceptibility testing and ratings
A standard national method for testing the susceptibility of flora species and ecological communities to P.  cinnamomi is developed and used nationally.
Medium priority, medium term
 

 
 
Objective 2: To develop and apply management actions that will minimise or mitigate the threat of P. cinnamomi
 
A nationally applicable risk assessment process (Action 2.1) will enable comparative assessments of high-value sites and habitats that are highly susceptible to P. cinnamomi. Management priorities will be able to be set with confidence and with lessened reliance on subjective assessments.
 
Land managers can improve their ability to deal with infestations from a range of management options. The development of management plans and the adoption of the ‘National Best Practice Management Guidelines’ (Action 2.2) for areas of high conservation value will minimise the risk of spread to uninfested areas. Adoption of these guidelines will also provide a risk-based assessment of the likely need and timing of management actions.
 
Monitoring and surveillance of infested and at-risk uninfested areas (Action 2.3) will provide information on disease outbreaks as well as the distribution, prevalence, and incidence of P. cinnamomi. The ‘National Best Practice Management Guidelines’ (O’Gara et al. 2005) provide decision-support systems to help land managers choose locally appropriate diagnosis and management methods, and to decide when to apply them. Lateral flow devices have been shown to be cost effective in identifying plants infected with P. cinnamomi in the United Kingdom. These can be used as an early diagnosis tool by landholders, managers and surveillance officers (Action 2.4).
 
The Department of Environment and Conservation, Western Australia, has observed a significant difference in the levels of impact upon susceptible species which are unable to recruit back into a site after P. cinnamomi infestation. Management methods should take into account the different level of impact when monitoring and managing short and long term impacts.
 
In the case of species at extreme risk, ex situ cultivation is a conservation option (Action 2.5).
 
Further research into the effectiveness and non-target implications of current management practices, particularly those involving the use of phosphite, would enable these practices to be adopted with greater confidence on a broader scale (Action 2.6).
 
Some taxa of plants display resistance mechanisms in response to P. cinnamomi infection and there is also considerable variation in resistance between species within the same genus or subgenus. Enhancing the process of natural selection for tolerance may be a longer term management option for many taxa. Future research may also allow for the transfer of resistance genes into those taxa that at present appear to have no resistance. An improved understanding of the genetic basis of resistance and genetic diversity of P. cinnamomi will be essential. Initially, the availability of samples of P. cinnamomi cultures, isolated and collected from a wide range of natural ecosystems, would facilitate any research (Action 2.7).

Objective 3: To strengthen training, education and communication of land managers in the science and management of P. cinnamomi
 
Better awareness and surveillance in high-risk regions and high-value sites can lead to early detection of infestations. This, coupled with efficient sampling and diagnostic systems, will be important in minimising the spread within and from infested areas. The integration of P. cinnamomi surveillance into other field surveys, such as for weeds, would provide efficiencies in operational procedures as well as increased awareness of the pathogen and its impacts (Action 3.1).
State and territory governments offer training in natural resource, weed and pest management to farm and park managers. The integration of P. cinnamomi best practice management into such coursework is desirable (Action 3.2).
Land managers should have an understanding of the basic symptoms and management practices associated with introduction and spread of P. cinnamomi, based on up-to-date knowledge and operational experience (Action 3.3). The use of infested material for road works has historically been one of the primary mechanisms of spread of the disease. The use of pathogen-free material would reduce this mechanism of spread. However, existing industry-specific codes of practice for the management of P. cinnamomi are often ineffective and need to be targeted towards land managers or developers who supply nursery materials, transport soil, quarry, farm or build roads. Quarry material is not subject to voluntary certification. The Nursery and Garden Industry Association raises awareness of issues associated with plant growth media (including mulch sources) and facilities, however, availability of non-certified material elevates risk. Leisure activities, such as tourism, hiking and mountain-biking, also pose a threat and appropriate communication strategies need to be implemented. Government agencies will need to identify the gaps in implementing best practice and certification measures to institute safeguards against the inappropriate disposal of P. cinnamomi infested material.

Objective 4: To assess P. cinnamomi impacts in Australia.
 
The scope and significance of the impact of P.  cinnamomi on ecological communities and the landscape is poorly understood. An assessment of the environmental impact or the impact on more direct commercial activities is overdue. Quantitative analysis of the effects of P. cinnamomi on biodiversity, the environment, economy, and social and cultural values will provide an assessment of the environmental and community costs of the pathogen. This would provide a practical basis upon which to allocate resources to manage the problem.

3. Duration, implementation and evaluation of the Plan
3.1 Duration of the Plan
The TAP has been written to reflect the fact that the threat abatement process is likely to be ongoing, as there is no likelihood of nationally eradicating P. cinnamomi in the foreseeable future.
3.2 Cost of the Plan
.
Investment in many of the TAP actions will be determined by the level of resources that stakeholders commit to managing the problem. The total cost of implementation therefore cannot be quantified at the time of writing.
 
This TAP provides a framework for undertaking targeted priority actions. Budgetary and other constraints may affect the achievement of the objectives of this plan and, as knowledge changes, proposed actions may be modified over the life of the plan. Australian Government funds may be available to implement key national environmental priorities, such as relevant actions listed in this plan and actions identified in regional natural resource management plans.
3.3 Implementing the Plan
The Australian Government Department of the Environment, Water, Heritage and the Arts (DEWHA) will maintain its strong links with state and territory agencies and with local and regional bodies that are responsible for the management of Phytophthora incursions.
DEWHA will facilitate the implementation of this Plan, encouraging involvement of key stakeholders and experts in the research and management of P. cinnamomi. DEWHA will seek stronger coordination of national action on P cinnamomi under the AusBIOSEC national biosecurity arrangements. The Australian Government will implement the Plan as it applies to Commonwealth land and will act in accordance with the provisions of the Plan. DEWHA will draw on expertise from state and territory agencies, and non-government organisations.
 
The management of P. cinnamomi will be achieved primarily through informing the actions of land owners, leaseholders and parties who access or manage land. Recreational users, tourism, agricultural and horticultural industries will also be engaged. The TAP identifies the importance of collaboration between all stakeholders in implementing the TAP. Local governments assist in delivering state and territory priorities at a local and regional level and can create local laws to control certain aspects of land use which also has implications for the management of P. cinnamomi in the landscape. Land managers at all levels need to implement prevention and management actions.
 
Research priorities for P. cinnamomi should focus on susceptibility determination and improved management options. Longer-term research options will depend upon the success of other measures, and should include investigating natural selection for tolerance in threatened taxa and the transfer of resistant genes into those taxa that at present appear to have no resistance.
3.4 Evaluating, implementing and reviewing the Plan
Section 279 of the Environment Protection and Biodiversity Conservation Act 1999 provides for the review of this TAP at any time and requires that it be reviewed at intervals of no longer than five years. If evidence is found that the practices recommended in the TAP need to be updated or modified to prevent species or ecological communities becoming threatened, or that the effectiveness of the TAP can be improved, it can be revised within five years of the release of this Plan.

APPENDIX A
 
Threatened flora species known to be susceptible to Phytophthora cinnamomi
 
The following species listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 have been identified as being susceptible to Phytophthora cinnamomi. In the absence of complete research in this area, the list is limited and only indicative of susceptibility in specific areas. A list of over 1000 known native hosts of P. cinnamomi in Australia is contained in the National Best Practice Guidelines (O’Gara et al. 2005). Further research into susceptibility in different areas is desirable (see Research Actions for Objective 1).

The distribution of taxa is indicated by the state or territory in which they have been recorded: NSW/ACT: New South Wales and the Australian Capital Territory, Qld: Queensland, SA: South Australia, Tas: Tasmania, Vic: Victoria, WA: Western Australia.
 
The ‘isolation’ column indicates the circumstances under which susceptibility to P. cinnamomi was identified. Species from which P. cinnamomi has been isolated have been separated according to whether
·     Identification was made in plants growing in the wild
·     Identification was made in plants grown in cultivation (mostly botanic gardens)
·     Identification was made from ex situ laboratory tests, in a glasshouse environment. For species indicated by *, susceptibility was identified by inoculating propagated plants in the field.
