On 21st January 2014 the UK published a plant health risk register. This can be found at http://www.fera.defra.gov.uk/plants/plantHealth/pestsDiseases/riskRegister.cfm
It brings together the outputs from Pest Risk Analyses and other risk assessment work, carried out in the UK and elsewhere. It assesses the impacts and the possibility of establishment of nearly 700 organisms and will be used by policy makers, industry and academia in their work.
Production of the risk register was one of the recommendations of a task force on Tree Health and Plant Biosecurity set up by Ministers as one response to the outbreak of Chalara fraxinea in the UK in 2012.
