The Lesser Horseshoe Bat Conservation Handbook Includes Advice on Greater Horseshoe Bat Conservation

About this book

The first edition of The Lesser Horseshoe Bat Conservation Handbook was published in 2008 and has been widely used by ecological consultants and planning authorities in Britain and Ireland, as well as further afield in mainland Europe. The work of Vincent Wildlife Trust (VWT) on this species has continued and developed following the original publication, complemented by workshops and training courses delivered by the Trust to a wide range of stakeholders. The Trust has hosted teams working on horseshoe bat conservation projects from across Europe and has, in turn, visited these projects. This exchange of ideas, along with the extensive feedback received over the years, has led to the production of this second edition of the handbook.

Although some of the conservation interventions in this new edition will be familiar to readers of the original handbook, ideas have developed and moved on, and new approaches to enhancing roosts have been included. The Trust has also strengthened the landscape-scale perspectives in addressing various conservation issues. Feedback on a few of the ideas suggested in the first edition has led to their withdrawal – such as the cool tower, which did not prove as effective as was hoped – and more sustainable alternatives have been suggested. Issues that were slightly off our radar in 2008, such as the threats around artificial lighting at night and the increasing effects of our changing climate, have been addressed. With so much sharing of ideas and discussions with colleagues on the Continent, this edition has a much more pan-European scope than its earlier counterpart.

VWT is very much an evidence-led organisation, which is reflected in its approach to trying to solve conservation issues for lesser horseshoe bats. The first part of this handbook lays out the ecology of the species in detail, as the Trust believes having a sound ecological knowledge base is essential to the delivery of effective conservation. Although the ideas presented here are based on real-life examples, no two situations are the same. It is hoped that, taking the knowledge of the species’ ecology and the concepts here presented, practitioners will adapt the ideas for their unique circumstances.

While this handbook focuses on the lesser horseshoe bat, it also contains information on managing roosts for greater horseshoe bats. The two species have very similar roosting requirements, and if practitioners are seeking to enhance roosts for greater horseshoe bats, there is much that is interchangeable. Throughout this new handbook, guidance is provided on the modifications for lesser horseshoe bats that can be used in greater horseshoe bat roosts and on where adjustments for the larger species are necessary.

Biography

Henry Schofield joined Vincent Wildlife Trust (VWT) in 1990, researching the conservation biology of lesser horseshoe bats. He set up the first of VWT’s lesser horseshoe bat reserves, focusing on providing evidence-led conservation interventions to enhance the roosts for their resident bat populations. Horseshoe bat conservation has been a lifelong passion for Henry, but along the way, he has also worked on rare tree bats and small carnivores. Although recently retired from VWT, Henry is still active in bat conservation and is an Honorary Fellow at the University of Sussex, carrying out conservation-directed bat research on a range of European species.
