This second edition of Greig-Smiths’ book on vegetation analysis has been clarified and improved as to methods and means of handling ecological data. The book is admittedly a statistical quantitative approach, and a non-statistician will have trouble understanding the book, at least in its details. However, ecology as a science has not advanced rapidly because of the complexity of its interrelating factors, and to workers in the field it is obvious that the statistical approach is the only solution to this complexity.
