Scotland has a remarkable assemblage of species and habitats with Atlantic, montane, boreal, arctic-alpine, and oceanic habitats in close proximity. However, pests and pathogens represent an increasing threat to these natural assets, and a particular challenge is the sheer complexity of the diversity of the natural environment in terms of the number of species that may be impacted.
Scotland is internationally important for its resources of blanket bog, heather moorland, Atlantic rainforests, montane native woodland (e.g. Caledonian Pine forests) and high nature value farmland (e.g. machair). These habitat types represent a major tourism draw to Scotland as well as being of significant value for biodiversity and ecosystem service provision. Increasing global trade is, however, resulting in native species encountering novel pests and pathogens, and in addition, changing climatic conditions can increase susceptibility of species in the natural environment to endemic plant health threats.

1. What is the overall goal and vision for PHC and how do we articulate this for different groups and sectors?
2. What do we want to communicate, when and to whom?
3. How do we want to communicate to different audiences and for these different purposes?
4. How do we optimise budget and human resource in communicating about plant health?
Impact: The outcome of this project will be a Communication Strategy outlining the goal of communication, roles and responsibilities and a process, including an annual cycle of reflection to permit update or modification on a regular basis and linking to the communication matrix.
Therefore, a small desk study was undertaken by Forest Research to provide a firmer evidence base and begin to identify the nature and scale of alder health problems in Scotland. A request to Scottish Forestry’s Tree Health team for information of sites at which alders are currently displaying symptoms of poor health identified 15 sites. The symptoms displayed at these sites differed widely and are a strong indication of different agents being associated with the decline of alders at different sites. Collation of the data for these sites is now complete and provides a firm basis upon which to carry out targeted field visits when fieldwork becomes feasible. Discussions are underway between experts at FR, RBGE, Hutton, and NatureScot to consider options for fulfilling the objectives of the original project call.
Impact: This fellowship will generate an increased understanding of current and future plant health threats to the natural environment in Scotland and identify key knowledge gaps, and deliver practical steps and actions to minimise risks and negative and provide evidence-based advice to inform future policies to help safeguard this sector.
Impact: Keep plant health and biosecurity at the forefront of our stakeholders’ minds, and a high priority for them, raising stakeholder awareness about the risks from plant pests and pathogens and the solutions available for their management and control, and raising the profile of the Plant Health Centre and our online resources.
This project is being conducted on behalf of the Plant Heath Centre, Scottish Forestry and NatureScot and aims to better characterise the threat of BBB to Scotland.
Impact: Draw together available evidence and, where feasible, gather new evidence relating to the threat of Bronze Birch Borer to Scotland; and provide information to inform contingency plans and make recommendations for further work to refine the evidence.
Impact: Identify accurate, efficient and trusted sources and test whether these sources are influential in appropriate usage of control options across key arable regions and crop types, plus intervention tools or methods that might be needed to manipulate or change how information flows; bespoke to the needs of the Scottish stakeholder network.
Impact: Deliver recommendations as to the suitability of vector trapping methods and eradication strategies, if deployed in Scotland.
Impact: Determine the main barriers to ensuring that future planting for environmental restoration and conservation will minimise plant health risks.
Impact: Provide Scottish Government policy with an assessment of the major biosecurity pitfalls and opportunities arising from large-scale landscaping plantings.
Impact: This project will enable policy to identify and prioritise plant biosecurity vulnerabilities from non-specialist and online horticultural sales.
Chemical forms of plant protection are widely used in Scottish agricultural, horticultural and forestry production plus for amenity and natural environment management purposes. The availability and use of active substances in pesticides are closely regulated and increasing concern over human health and environmental impacts has led to a greater likelihood that some existing approvals will be withdrawn and/or that approvals for new products will not be granted. Potential impacts from withdrawal of these pesticides are of policy interest and this summary report builds on the data and results from project PHC2018/15 (Potential impacts arising from pesticide withdrawals to Scotland’s plant health) and uses case studies to understand the likely magnitude and distribution of potential impacts and how they may be mitigated.
The use of pesticides to manage plant pests and diseases is a key management intervention across plant health sectors, particularly in agriculture, horticulture and commercial forestry production. Pesticide withdrawals through legislation, coupled with resistance development and their impact on plant health, have emerged as key concerns for Scottish plant health stakeholders. This project quantifies the impacts on Scottish plant health that will arise from pesticide withdrawal scenarios and sets this in the context and time frame of alternative management tools.
This project constructed a modelling framework which combined epidemiological and economic modelling. The modelling framework was used to study predictions of spread and economic impact of pests which are not currently in the UK, including Xylella fastidiosa, Candidatus Liberibacter solanacearum (Zebra chip) and Ips typographus (Eight toothed Spruce Bark Beetle).
Impact: A web/desktop application is available to the PHC and Scottish Government to analyse the effects of climate change on the spread and economic impact of new threats.
This project has expanded the PHC online Resource Bank for plant health threats to the Natural Environment sector in Scotland to include information sources for the remaining three sectors (Forestry, Agriculture and Horticulture). Information sources for Forestry, Agriculture and Horticulture were compiled and evaluated, and a Knowledge Bank relevant to each sector is now online at the PHC website, creating a comprehensive and unique signposting resource for plant health information with relevance to Scotland.
The Plant Health Centre completed an in-depth review of its first 18-months of activity for our funder (the Scottish Government through RESAS) in September 2019. While the full report is not yet available to the public, we have created a summary leaflet that outlines out achievements over this period.

Development of an online, user friendly plant health resource bank for the Scottish Natural Environment
The aim of the project PHC2018/11 was to compile a resource to be embedded within the Scottish Plant Health Centre (PHC) website, with the following three main purposes: 1) To direct users to existing, comprehensive and reliable plant health information resources; 2) To provide information on selected plant health threats to the natural environment, particularly invasive non-native species; and 3) To direct users to appropriate government agencies and resources and advise users on steps to take should a suspected statutory pest or disease be encountered.
Webpages have been developed which provide the following:
1) a listing of the first most pressing plant health threats to the natural environment in Scotland;
2) a user-friendly web template, populated with links to information about these major threats and other topics relevant to plant health in the Scottish natural environment; and
3) summary pages providing guidance on biosecurity and control of diseases in this sector, for which other resources were not easily available.
The aim of the project was to review existing websites and smartphone apps currently available and applied in the plant health sector and to assemble a detailed overview covering the following points:
- What options are available in terms of mobile software applications for plant health?
- What is their primary purpose?
- Who is the target audience (growers, plant health professionals, citizen science, …)?
- Which plant health sectors do they cover?
- Are they reliable and accurate?
- Is information submitted to a central database? If so, how is this information used?
- Could they be used globally, or are they limited to certain geographic regions?
Heritage gardens play an important role in plant conservation. They house collections gathered over decades or even hundreds of years, including varieties of plants that may be overlooked elsewhere, fostering heirloom varieties and preserving biological diversity that is the raw material of adaptation. As well as being beautiful and tranquil sites of cultural heritage, these ex-situ resources are treasure troves of biological diversity. Arduaine Gardens shows us that tough choices can be necessary and important to preserve these collections and the surrounding environment.
