Summary

In an attempt to protect the nationally rare red helleborine Cephalanthera rubra from herbivory by slugs and snails during the growing season, copper rings were placed over emerging shoots in the spring and summer. Subsequent monitoring revealed that there was no evidence of any slug damage to plants protected by such rings.
