This book contains a collection of articles by Thompson and coauthors with the stated purpose of describing the latest sampling designs and counting (estimation) techniques for reliably estimating occupancy, abundance, and other population parameters of rare or elusive plants and animals. It is written primarily for the field ecologist who has some background in population monitoring and survey sampling but who has not kept current of new developments in sampling and estimation concepts targeted specifically at rare and elusive species. After reading this book, you will have a good appreciation of general difficulties associated with monitoring rare species but also many ideas to accomplish the task.
