Assessment of large-scale plant biosecurity risks to Scotland from non-specialist and online horticultural sales
Impact: This project will enable policy to identify and prioritise plant biosecurity vulnerabilities from non-specialist and online horticultural sales.
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 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.
