The Bearing Witness for Wildlife Bat Roost Mitigation Project recognised that there is a lack of evidence and evidence-based guidance on how effective replacement bat roosts, provided during the development process, are. There is also a lack of evidence on how well mitigation designs are communicated and implemented on the ground. This could result in developers acting unlawfully.

The project delivered a Mitigation Case Studies Forum in January 2017, bringing together representatives from across the sectors to share experience and best practice. The proceedings document can be downloaded for free here: Mitigation Case Studies Forum 2017 proceedings document

The project collected evidence on the implementation and efficacy of bat roost mitigation and compensation through two seasons of fieldwork and produced a paper published by Conservation Evidence that will be used to update industry guidance:

"The implementation and effectiveness of bat roost mitigation and compensation measures for Pipistrellus and Myotis spp. and brown long-eared bat (Plecotus auritus) included in building development projects completed between 2006 and 2014 in England and Wales."

Finally, the project will also deliver a new 'Roost' website of bat roost mitigation case studies and an associated 'Roost' award for good practice.
