UK Bat Mitigation Guidelines 2023

The Bat Mitigation Guidelines reflect the significant changes in our understanding of bat ecology and mitigation practice since the publication of English Nature’s (now Natural England’s) Bat Mitigation Guidelines (Mitchell-Jones, 2004). They have been produced by synthesising the most up-to-date research evidence available at this time and the expertise of bat ecologists drawing on decades of experience. That they have been almost five years in the drafting reflects both the extensive amount of additional information available and the complexities of delivering successful bat mitigation and compensation. It also highlights the dedication and huge time commitment volunteered by the authors, supported by the steering group and all those who responded in detail during the consultation phase.

As practitioners, you can help us to develop the evidence base for future editions by monitoring and recording the outcomes of projects you have been involved in and sharing your successes and failures. You can submit your case study examples of project design, novel approaches and outcomes using this form.
