Phytophthora Pluvialis Infection Risk Scores For 11,098 Scottish Forest Fragments

11,098 forest fragments in Scotland containing Douglas fir or western hemlock are mapped with risk scores for Phytophthora pluvialis infection. The dataset integrates risk factors like climate suitability, proximity to infected sites, and recent planting data, developed through stakeholder surveys and workshops. Risk scores are summarized across conservancies, local authorities, and active demarcated areas.

Use Cases

• Model infection spread by analyzing risk scores relative to proximity to other fragments and infected sites.
• Prioritize inspection resources by ranking forest fragments based on integrated climate suitability and recent planting data scores.
• Assess regional vulnerability by summarizing fragment risk score distributions across conservancy and local authority boundaries.
• Correlate outbreak patterns with environmental factors using risk scores that incorporate water course proximity.

Strengths

• Covers 11,098 distinct forest fragments, providing granular spatial coverage.
• Risk scores are derived from multiple integrated factors agreed upon by 15 cross-sectoral stakeholders.
• Data is intersected with administrative boundaries (conservancies, local authorities) for regional analysis.

Limitations

• Risk scores are model-based and integrate proximity factors, not direct field measurements of infection.
• Geographic scope is limited to Scotland, though the pathogen is present in other UK regions.
• The dataset focuses on two host species, though other pine species are known to be susceptible.
