This book introduces the suite of techniques known as 'distance sampling'. Of particular significance in this update is the chapter on study design and field methods, which has been extensively re-written and extended. New technologies such as laser range finders, theodolites and the Geographical Postioning System (UPS) are discussed, and advice is given on a wide range of survey methods. Analysis methods have been generalised, throughout the use of various types of multipler.
