Contingency planning



Protecting the nation against natural threats (including plant health) and hazards is one of Defra’s top priorities. Under the Plant Biosecurity Strategy for Great Britain strengthening protection against plant pests and diseases inland includes a commitment to develop effective contingency plans and clear governance to help eradicate or minimise the impact when outbreaks occur.

The Defra Generic Contingency Plan describes how Defra and operational partners prepare for, and would respond to, an outbreak of a plant or bee pest or disease in England.

Pest specific response plans prepared by Defra and the Forestry Commission describe how the plant health service for England will respond to outbreaks of certain high risk pests where additional measures over and above those set out in the overarching Defra contingency plan for plant health in England are required.

Please see the reporting a pest and disease webpage for the most up-to-date contact details for the UK Plant Health Services.
