This book contains the papers presented at the conferences of the International Association Vegetation Science of Pirenopolis (2016) on Applied Mapping for Conservation and Management: from Plant and of Palermo (2017) on Vegetation Patterns in relation to multi-scale levels of ecological complexity: from associations to geoseries. The reports refer to general themes (semiological bases of mapping, dynamic-catenal mapping, nature conservation, plant biodiversity, biogeography, and geosynphytosociology) and their application to vegetation in different parts of the world (Andes of Bolivia, California, Kaga Coast in Japan, Southeastern USA, Morocco, Europe: Carpathians mountains, Swiss Alps, Sicily, Southern Portugal, Spain, and French Atlantic coastal). One of the benefits of the book is that it offers the possibility of comparing the different methodologies used in very different types of vegetation in the world (Boreal, Mediterranean, Tropical, Neotropical, etc.). The book is intended for researchers, Ph.D. students, and university professors.
