                  <gco:CharacterString>1) Acquisition :
Relevés réalisés à l'aide d'un GPS à main Magellan 315 engendrant une précision de l'ordre de 5 m.
Observations de terrain concernant la taille des clones, leur état et autres commentaires.

2) Traitement :
Synthèse des relevés de clones de Spartina anglica, maritima et cf maritima (spartine X) observés lors des levés de terrain réalisés par Yves-Michel Le Nindre entre 1999-2000, 2003-2004 et 2005-2006 sue les côtes Est et Sud du Bassin d'Arcachon.
Cette couche a été créée en rassemblant les points d'observation relatifs à cette thématique sélectionnés dans les couches/bases de données suivantes : "Obs_dpm_juin" (réf. [1]), "SIBA_Sud" (réf. [2]) et "Obs_2001_YMLN" (réf. [3]).
Les points de type SIBA concernent la côte Est (campagnes de 2003-2004).
Ceux de type SIBAS concernent la côte Sud du Bassin et ont été relevés en 2005-2006.
Ceux de type YLN concernent la côte Est (campagne de 1999-2000).

Plusieurs observations peuvent avoir été faites en un même point; on retrouve ces informations dans la liaison plusieurs-plusieurs qui lie cette couche à la table Espèces (Etat, Etat_Abrev, Taille_Cat, Espacement, Enlever, Commentaire).

5) Remarques :
Spartina cf maritima se distingue bien sur le terrain de la forme ubiquiste de S. maritima.
S. maritima apprait plus rase, vert sombre, avec une feuille enroulée, et ne fleurit qu'exceptionnellement à la latitude du Bassin où son développement est essentiellement végétatif. Bien que présentant le plus souvent 2 à 3 épillets seulement, sa description correspond à celle de S. alterniflora, qui est la forme envahissante des estrans américains. Cependant, des examens caryotypiques faits par le laboratoire de Botanique de l'Université de Rennes 1 (M. A. Ainouche) l'apparentrait également à l'espèce maritima. Malgré cela, cette variété s'identifie aisément et, par sa floraison et sa répartition verticale, possède un grand pouvoir colonisateur.</gco:CharacterString>
