Mariella is a social anthropologist and senior social researcher at Forest Research with over 15 years of experience in agriculture, fisheries and forestry sectors in the UK and internationally. Mariella currently leads a number of interdisciplinary research projects and/or work packages related to the human dimensions of species management, tree and plant biosecurity, stakeholder engagement and risk management and communication. Recent projects have covered species such as Dothistroma needle blight, Asian longhorn beetle, Oak processionary moth, Emerald ash borer, Phytophthora sp., grey squirrels and rhododendron ponticum. Mariella also established and chairs the IUFRO Working Party on the “Social Dimensions of Forest Health” and is an Honorary Fellow at the University of St Andrews.
This project will extend the database, creating GIbase 2.0., establishing search functions for planning portals across Scotland, automatically generating notifications of projects that meet specific criteria relating to project scale and type. This will allow both higher resolution data to be recorded and also ensure that GIbase 2.0 captures the most current schemes under development or in early-stage planning.
This project will Map the diversity and abundance of plant species used in green infrastructure across Scotland, and record this data in GIbase 2.0. It will use the UK PHRR to create relative risk profiles for each plant species, and, for commonly planted species, create high quality data sheets using published research, providing a valuable asset to policy-makers, local planning authorities, Green Infrastructure designers and developers.
This project was selected for funding from the Project Call: “Enhancing preparedness against pests and diseases: plugging evidence gaps for Scotland”.
PHC2021/08 will implement an Action Research approach, delivered through workshops co-designed with network organisations, to better understand current plant biosecurity risks in several sectors, to identify their plant health knowledge needs, and to begin to embed biosecurity training within existing organisations, programmes and processes.
The outcomes of the project will be:
• An enhanced understanding of the knowledge and training needs of different sectors and the identification of biosecurity actions that will fill some of the gaps identified by PHC2019/04/05/06
• The identification of further training needs and potential approaches to address the problems identified
• A legacy of close working relationships between the PHC and several network organisations, key to future plant biosecurity research or training delivery activities
Drawing upon and summarise existing literature, in addition to engagement with experts and practitioners with knowledge of existing sectoral practices in Scotland, UK and internationally, as well as gap analysis, the project will generate a better understanding of the rationale for taking precautions and an improved evidence base with which to justify taking action, answering four main questions:
• What are the current barriers to adopting precautionary measures?
• How can barriers be reduced?
• What are the limitations of the current risk assessment process?, and
• What are the priority areas for action and further research?
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: 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.
Impact: Improved understanding of concepts and options amongst the Scottish stakeholder community; a basis for gap analysis by the PHC.
The Bronze Birch Borer (BBB, Agrilus anxius) is a major threat to birch trees. This project had co-funding from Scottish Forestry and NatureScot and undertook evidence gathering to assess the threat BBB poses to Scotland, inform risk assessment, surveillance and contingency planning, and identify key risks and knowledge gaps.
PHC commissioned an assessment of large-scale biosecurity risks with a focus on three areas of concern:
- non-specialist and online horticulture sales;
- landscaping and infrastructure;
- planting for environmental benefits.
An additional area was the potential for modelling to support decision making across these areas of concern. This policy report summaries each report and highlights the key findings and suggested actions.
Assessment of large-scale plant biosecurity risks to Scotland from non-specialist and online horticultural sales
This project focused on an initial exploration of tree and plant biosecurity risks to Scotland arising from large-scale movement of plants via non-specialist (those for which plants are not their primary product type, e.g., supermarkets, DIY and lifestyle stores) and online plant retailers. By better understanding the characteristics of these retailer types, the plant health behaviours they undertake, and the challenges they face, potential avenues were offered for greater engagement and collaboration on biosecurity with this important, but understudied and hard to reach sector.
Assessment of plant biosecurity risks to Scotland from large scale plantings for landscaping and infra-structure projects
Planting for large-scale landscaping and infrastructure can typically involve tens of thousands of individual plants, potentially threatening plant health in Scotland due to the biosecurity risks of imports and widespread planting of infested or diseased plants. This project aimed to understand the extent and means to mitigate against such plant biosecurity risks with a focus on mapping the pathways from plant specification through to planting and establishment and highlight different biosecurity awareness for actors, in decision-making and procurement processes.
Assessment of plant biosecurity risks to Scotland from large scale tree plantings for environmental benefits
This report features five case studies from across Scotland and examines risks associated with large scale tree planting schemes, levels of awareness around pests and diseases, and how the decisions and actions of those involved can serve to reduce or exacerbate pest and disease related threats and long-term tree health. Each case study was unique in respect to their combination of location, site conditions, ownership, management objectives, species choice, supply chains and management activities. By highlighting best practice and lessons learned, it was hoped to ensure that future planting schemes can be successful and, importantly, reduce the likelihood of pests and diseases being introduced and spread into the wider environment.
The potential of ecological and epidemiological models to inform assessment and mitigation of biosecurity risks arising from large scale planting
Large scale planting projects linked to infra-structure such as transport networks and major housing projects or to planting for environmental benefits (e.g., urban greening, woodland restoration) pose high biosecurity risks due to the high number and types of plants involved. This report focusses on whether and how ecological and epidemiological model frameworks can inform assessment and mitigation of biosecurity risks from large scale planting using a combination of literature review and stakeholder engagement. The project aimed to identify priority steps to develop more useful models and tools for assessing biosecurity risks from planting in the future.
