Ecological Cartography

This volume is a description of the principles and purpose of vegetation mapping at thelandscape unit scale. The mapping process is based on the principles of phytosociology. Wedistinguish four nested typological vegetation units from the plant community to the landscape cell from the series to the vegetation geoseries. Mapping aims to delimit landscape cells as a priority andto relate them to a known habitat typology.Before the start of the mapping of an area it is essential to have a good knowledge of thevegetation units that are present. In this regard the catalogs prepared by Dr. Aouadj and Khatir (2017-2024) which describe the vegetation units their distribution their ecology and their floristicprocession are essential. Vegetation mapping at the scale of landscape units is based on the physiognomy map and theecological envelope map. These maps propose a homogeneous spatial division of the territory basedon physiognomic and ecological criteria respectively. The physiognomy map is based on photo-interpreting imagery and analyzing satellite imagerytime series.
