This book is the result of my interest, love and dedication to South American camelids. In this book the reader will find valuable information about this species of animal commonly known as guanaco, which is found in the National Reserve of Calipuy between the provinces of Santiago de Chuco and Viru in the Department of La Libertad-Peru. This work is divided into 4 chapters: To know the characteristics and social behavior of this species; it shows in detail what is the Calipuy National Reserve; the current legal regulations that exist for this species and shows a glossary of ecological terms that are used when working with this species and in these areas. It will also serve as a reference work for students, technicians, professionals and interested people who want to learn about this species.
