Actions Indicated

  • show / hide

Action

Statutory action against findings. Priority for additional regulation on imported plants to help further mitigate against introduction, as recommended in the UK PRA.

General Comments

Unlikely to kill elms but may defoliate. Could exacerbate damage already caused by Dutch Elm Disease (DED) and pose threat to small populations free from DED and resistant varieties. Additional requirements on plants for planting could help further mitigate against risk of introduction.
