| Abstract: | Bats are ecologically and economically important mammals. The life histories of bats (particularly their low
reproductive rates and the need for some species to gather in large aggregations at limited numbers of roosting sites) make their
populations vulnerable to declines. Many of the species of bats in the United States (U.S.) and territories are categorized as
endangered or threatened, have been candidates for such categories, or are considered species of concern. The importance and
vulnerability of bat populations makes monitoring trends in their populations a goal for their future management. However,
scientifically rigorous monitoring of bat populations requires well-planned, statistically defensible efforts. This volume reports
findings of an expert workshop held to examine the topic of monitoring populations of bats. The workshop participants included
leading experts in sampling and analysis of wildlife populations, as well as experts in the biology and conservation of bats. Findings
are reported in this volume under two sections. Part I of the report presents contributed papers that provide overviews of past and
current efforts at monitoring trends in populations of bats in the U.S. and territories. These papers consider current techniques and
problems, and summarize what is known about the status and trends in populations of selected groups of bats. The contributed
papers in Part I also include a description of the monitoring program developed for bat populations in the United Kingdom, a
critique of monitoring programs in wildlife in general with recommendations for survey and sampling strategies, and a compilation
and analysis of existing data on trends in bats of the U.S. and territories. Efforts directed at monitoring bat populations are
piecemeal and have shortcomings. In Part II of the report, the workshop participants provide critical analyses of these problems
and develop recommendations for improving methods, defining objectives and priorities, gaining mandates, and enhancing information
exchange to facilitate future efforts for monitoring trends in U.S. bat populations. |
