Bat Roosts In Trees

This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.

This guide provides descriptions of when the bat species resident in Britain and Ireland use natural and human-made rock habitats, how they use them, and the environments each species occupies therein. For the first time it brings together findings from historical scientific investigations, useful photographic accounts and open-access biological records, along with a rich seam of new data – all in a practical and user-friendly structure. The book encompasses: ~ Descriptions of the features that a climber, caver or professional ecologist might encounter on and in rock habitats where bats roost. ~ Recording criteria for both the physical and environmental attributes of different features and situations. ~ Identification of suitability thresholds against which the recorded information can be compared to assess the likelihood that a specific feature might be exploited by a particular bat species. ~ Suggestions for how to avoid mistakes and difficulties when performing a survey. The intention is that using this book will help generate standardised biological records which can feed into the fully accessible online database at www.batrockhabitatkey.co.uk. These data will be analysed to search for patterns that can increase the confidence in the suitability thresholds and help build roost features that deliver the environment each species really needs. As well as offering many new insights, this book allows the reader to participate in cutting-edge research.

Although bats are often thought of as cave dwellers, many species depend on forests for all or part of the year. Of the 45 species of bats in North America, more than half depend on forests, using the bark of trees, tree cavities, or canopy foliage as roosting sites. Over the past two decades it has become increasingly clear that bat conservation and management are strongly linked to the health of forests within their range. Initially driven by concern for endangered species—the Indiana bat, for example—forest ecologists, timber managers, government agencies, and conservation organizations have been altering management plans and silvicultural practices to better accommodate bat species. Bats in Forests presents the work of a variety of experts who address many aspects of the ecology and conservation of bats. The chapter authors describe bat behavior, including the selection of roosts, foraging patterns, and seasonal migration as they relate to forests. They also discuss forest management and its influence on bat habitat. Both public lands and privately owned forests are considered, as well as techniques for monitoring bat populations and activity. The important role bats play in the ecology of forests—from control of insects to nutrient recycling—is revealed by a number of authors. Bat ecologists, bat conservationists, forest ecologists, and forest managers will find in this book an indispensable synthesis of the topics that concern them.

Beginning a new series, a handbook of information about the 16 species of bats in British Columbia, Canada, with an emphasis on identification, distribution, natural history, and conservation of these unique mammals. Includes an identification key, maps, and bandw drawings of each species, plus general information on the bat life cycle and the study of bats. Annotation copyright by Book News, Inc., Portland, OR

This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Following extensive feedback from different user groups the Bat Conservation Trust has produced Bat Surveys for Professional Ecologists: Good Practice Guidelines (3rd edition). The guidelines were revised, updated and reviewed by experts and feature new chapters and content. This is the essential reference guide for professional ecologists working with bats.

This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat songs, dialects and calls. Part III discusses the influence of the environment on bat behavior, particularly with regard to roosting and foraging. This book addresses the needs of researchers working in behavioral sciences, evolution and ecology.
