About

The UK Plant Health Risk Register is a major step in implementing the recommendations of the independent Task Force on Tree Health and Plant Biosecurity. It is a tool for government, industry and stakeholders to prioritise action against pests and diseases which threaten our crops, trees, gardens and countryside. The Register is publicly available.

Plant pests not yet on the Risk Register may still be subject to plant health controls. The Plant Health Risk Register does not represent a comprehensive record of all pests of plant health concern, it is an evolving document to which more pests are being added every month.
