            <gco:CharacterString>Cette série de couches de données spatiales compilent les informations du thème "Sites protégés" dont les sites appartiennent au réseau Natura 2000 en Wallonie.

La Directive européenne 2007/2/CE - Directive INSPIRE - établit une infrastructure d'information géographique dans la Communauté européenne. INSPIRE s'applique à 34 domaines thématiques répartis en 3 Annexes. La présente série comprend les couches de données géographiques faisant référence aux sites protégés (Annexe 1.9).

Au sens de la Directive, les sites protégés sont : "des zones désignées ou gérées dans un cadre législatif international, communautaire ou national en vue d’atteindre des objectifs spécifiques de conservation". Chaque site protégé peut être attaché à un ou plusieurs mécanismes de désignation spécifiques. Parmi ces mécanismes se trouvent les sites protégés appartenant au réseau Natura 2000.

Natura 2000 est un réseau écologique européen de zones protégées naturelles (tourbières, forêts, rivières, rochers, grottes), semi-naturelles (prairies fleuries, pelouses sèches, landes, etc.) ou servant d'habitat propre à certaines espèces animales ou végétales. L'objectif global de ce réseau est de maintenir la biodiversité des milieux en définissant un cadre commun pour la conservation des habitats naturels ainsi que de la faune et de la flore sauvages sur le territoire des États membres.

Les sites "Natura 2000" sont proposés par les États membres, en application des directives européennes "Oiseaux" (2009) et "Habitats" (1992) qui constituent la base légale du projet. De 2002 à 2005, Le Gouvernement wallon a ainsi défini 240 sites Natura 2000 (Décision du GW - 24 mars 2005), ce qui représente quelques 221.000 ha, soit 13% du territoire wallon. Ces sites sont composés de forêts (feuillus, résineux, mixtes), terres agricoles, zones humides et cours d’eau. 

Les sites désignés comme appartenant au réseau Natura 2000 sont extraits de la série de couches de données INSPIRE "Sites protégés en Wallonie" qui reprend l'ensemble des sites protégés. La sélection se base sur le mécanisme utilisé pour procéder à la désignation des sites protégés et dont la valeur correspond aux sites appartenant au réseau Natura 2000.</gco:CharacterString>
