Populations of endangered Ozark big-eared bats Corynorhinus townsendii ingens are restricted to 19 essential maternity caves or hibernacula in Oklahoma and Arkansas and total only 1,600-1,800 individuals. Effective conservation and management should encompass many aspects of the species natural history and genetics.

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.

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.

The Ozark big-eared bat (Corynorhinus townsendii ingens) is an endangered subspecies of the Townsend big-eared bat (Corynorhinus townsendii). Human disturbance along with other factors resulted in population declines of the Ozark big-eared bat that were significant enough for the United States Fish and Wildlife Service (US FWS) to list the species as endangered in 1979. The US FWS recovery goal for the Ozark big-eared bat was an increasing or stable population over a 10 year period. To evaluate the progress towards this goal, I performed a population trend analysis over the last 10, 20, and 33 year periods. The total Oklahoma OBEB maternity population trend analysis did not show a trend but indicated a stable population for all three time periods. In addition I helped develop and test a new method for counting Ozark big-eared bats at maternity sites in Oklahoma using night vision video cameras and infrared lights as a viable alternative to current Ozark big-eared bat census techniques. The video method helps minimize human disturbance at the cave and allows people with very little experience to perform a reliable maternity count.
