Spatial risk analysis for Phytophthora pluvialis infection of Douglas fir and western hemlock in Scotland
Barwell, L.J., Turvey, K., Amankwaa, G., Asaaga, F., Cooke, D.E.L., Mitchell, R., Purse, B.V. (2025). Spatial risk analysis for Phytophthora pluvialis infection of Douglas fir and western hemlock in Scotland. NERC EDS Environmental Information Data Centre.

This dataset maps the risks of Phytophthora pluvialis infection for 11098 forest fragments in Scotland identified as containing the known hosts Douglas fir or western hemlock. Key risk factors and their scoring were agreed with 15 cross-sectoral stakeholders through a self-completion survey and two workshops. Fragment risk scores integrate climate suitability and proximity to other fragments/infected sites, recent planting of these hosts (forestry grant schemes), inspected premises and water courses. Infections of P. pluvialis have been reported on Douglas fir and Western hemlock in Cornwall, Devon, Cumbria, Wales and Scotland since the outbreak was first detected in 2021. Outside of the UK, pine species (Pinus radiata, P. strobus, P. patula) are also susceptible to the pathogen. The scored fragment data were intersected with the boundaries of conservancies, local authorities and active P. pluvialis demarcated areas to summarise the distribution of risks across regions in Scotland.
