Iberian and Macaronesian Vegetation Information System (SIVIM)

Abstract

SIVIM (Sistema de Información de la Vegetación Ibérica y Macaronésica; GIVD ID EU-00-004) is an information system designed for capturing, hosting, editing, analysing and exporting georeferenced plot data of Iberian and Macaronesian vegetation. It currently hosts 125,000 relevés, mainly from the northern half of the Iberian Peninsula and the Balearic Islands, and will grow to 150,000 relevés in the near future. SIVIM has been conceived to offer direct and free on-line access to relevés, tables, as well as to floristic, syntaxonomical and bibliographical records. The system also offers on-line software for edition and analysis of vegetation data (http://www.b-vegana.info). Scope: SIVIM is an Iberian and Macaronesian Vegetation Information System that aims to host about 125.000 relevés mainly from the Iberian Peninsula and the Balearic and Canary Islands.
