Project :A470 Penloyn – Tan Lan Trunk Road Improvement Scheme

Between 2004 and 2009 PENNINE Ecological undertook a combination of dusk and dawn surveys in relation to habitat use by bats along a new road alignment proposed as part of the Welsh Assembly A470 Trunk Road improvement scheme in the Conwy valley.

The surveys identified the presence of nationally important colonies of Lesser Horseshoe bats (Rhinolophus hipposideros) in the vicinity of the road. The surveys also established that Lesser Horseshoe bats were using the narrow section of the road at Plas Madoc as a crossing point.  

PENNINE Ecological advised a comprehensive mitigation package as part of a Countryside Council for Wales (CCW) European Protected Species licence application. This work was completed under licence and the new road section is now fully open.

To comply with the requirements of the Welsh Assembly & Countryside Council for Wales at this nationally important stronghold of Lesser Horseshoe bats, we continue to monitor the scheme to establish if impact upon bats has occurred since the completion of the work.
