Proposed Actions

 UK BAP Signposting Actions:

  1. Search the last known sites in Oxfordshire and Montgomery.  Sites are likely to require an abundance of veteran oak and adequate replacement trees.
  2. Research existing knowledge on the habitat requirements and threats to this species in Europe, to inform refinding and conserving this species in UK
