Using surveillance to monitor plant health

Biodiversity data collected through surveillance and monitoring can be applied to help to understand the spread and impact of plant diseases by establishing host distribution. Recent work includes:

  • An analysis of the distribution of important Ash in Great Britain, helping to determine areas at high risk from ash dieback (Chalara fraxinea).
  • A summary of the impacts of ash dieback on UK biodiversity, including the potential for long-term monitoring and further research on management scenarios.
  • Modelling to determine the co-occurrence of Rhododendron and Vaccinium myrtillus, to establish high priority areas for implementing control measures for Phytophthora infections.
  • An estimation of the area of UK Vaccinium myrtillus populations, which has helped to establish the scale of risk posed from the genus of Phytophthora pathogens.
  • Developing a national decision framework for deciding when to treat Vaccinium myrillus infected with Phytophthora, informed by evidence gathered through surveillance and monitoring.
  • Contributing to the Defra research project on “Future proofing plant health”, to enhance surveillance of plant disease, and ensure effective use of plant health data.
