good work with a despèces representative selection of French mountain parks. Description, drawing and very good pictures. Color by viewing a + a distribution of species by environment. The choice of a distribution of cash by mid request an adjustment period but eventually we learned more effectively on the present case. The negative is the ergonomics of the book. Unlike some other comments, do not suggest that this is an identification book to take the field. Almost 700g it's heavy. The large format is quite useful but rather that format is not practical to put in the backpack. The "tabs" does not facilitate page flip, they would be deleted as it would be as well. One quickly learns the order of the chapters in a book, no need to tabs that tend to corner. Similarly, as is done in other works, the species may appear in multiple environments. So very good book but no need to consider during the walks, it is a book to savor at home.
