Work in collaboration with relevant organisations on a strategy to prevent spread via nurseries and to protect rare juniper habitats.

General Comments

Significant threat to juniper and need to work with stakeholder and statutory conservation bodies to mitigate risk and protect unaffected areas where possible. Keep EU informed because other countries may wish to establish pest fee areas. Given establishment in some areas of the wider environment, statutory action will be limited to findings on nursery plants for movement.
