Map showing the spatial distribution of ecosystems identified in Sierra Nevada high mountain (southern Spain). Several sources were used to generate spatial distribution of ecosystem types. The Land Cover and Use Information System of Spain (SIOSE)(https://www.siose.es/) was used as base spatial information. Other technical reports also supported the spatialization and identification of the ecosystem types (e.g. Molero-Mesa, J.; Pérez Raya, F.; López Nieto, J.M.; El Aallali, A. & Hita Fernández, J.A. (2001). Cartografía y evaluación de la vegetación del Parque Natural de Sierra Nevada [Mapping and assessment of the vegetation of the Sierra Nevada Nature Reserve]. Department of the Environment. Regional Government of Andalusia). The main ecosystem types identified were: natural forests (Holm oak and Pyrenean oak forests [Quercus ilex and Q. pyrenaica], Scot pine forests [Pinus sylvestris var. nevadensis]), high-mountain shrublands (Juniperus communis), pine plantations, high-mountain grasslands ("borreguiles) among others. The data generated is stored as a vectorial file (shapefile). The coordinate reference system is UTM Zone 30N WGS84) (epsg:23030).
