From the reviews: "Population decline and extinction of many species is a worldwide phenomenon. Because quantitative methods are either lacking or not applied population declines are often poorly understood ... . The present book aims to contribute to close this gap by introducing several different quantitative methods that are useful to conservationists. ... The book has been written for graduate students and working conservation biologists. ... The authors succeeded ... in presenting the different methods in an understandable and simple way. ... I would recommend the book." (Michael Schaub, Basic and Applied Ecology, Issue 5, 2004)
