Atlas and Handbook of the Habitats of Spain
Description
Atlas that is part of the series that under the joint name of National Habitat Inventory and Taxons represent the range of syntaxonomic units (associations and alliances) corresponding to the Spanish habitat types of Annex I of Directive 92/43/EEC. It has the cartography of around 150,000 enclosures or representations of such units throughout the national territory, with 1,114 maps and 1,650,000 attributes and associated data. Carried out by the Ministry of the Environment. It is the result of the mapping of vegetation in Spain at a scale of 1:50,000, considering vegetation as an inventory unit. The realization of the Inventory used aerial photography and fieldwork for the delimitation of the enclosures, drawn on sheets of map 1:50,000 of the Army Geographic Service (SGE). In addition to polygons, conventional signs (asps, lines and crossed circles) were used for the representation of point, linear and cave Habitat structures. On the paper, a manual digitization of all the sheets was carried out, joining them later in maps by Autonomous Communities. An adaptation of the Habitat classification of Annex I was carried out to syntaxonomic units that can be mapped on the ground, resulting in the Technical Interpretation Document (TID), which disaggregated the 124 Spanish habitat types of Annex I into more than 1600 syntaxonomic associations and alliances. It includes the classification of the habitats of Spain with a file for each of them at Association level, a table of relationship of the habitats, descriptive sheets of them, the biogeographic classification of Spain and other information of phytosociological nature generated during the project. It includes habitat mapping and inventory rules as reference material.
