En d\u00e9pit d’un effort de recherche consid\u00e9rable \u00e0 l’\u00e9chelle mondiale, les r\u00e9sultats concrets des r\u00e9implantations de phan\u00e9rogames marines restent contrast\u00e9s. Bien que le pourcentage d’\u00e9chec soit \u00e9lev\u00e9, on peut consid\u00e9rer qu’il existe aujourd’hui un corpus m\u00e9thodologique fiable pour la r\u00e9implantation des principales esp\u00e8ces de phan\u00e9rogames marines (cf. exp\u00e9rimentations compar\u00e9es actuellement r\u00e9alis\u00e9es dans le cadre du programme RenforC en Corse). La croissance tr\u00e8s lente de Posidonia oceanica<\/em> fait que, apr\u00e8s plusieurs d\u00e9cennies apr\u00e8s les premi\u00e8res exp\u00e9rimentations en M\u00e9diterran\u00e9e, il n’existe pas encore de v\u00e9ritable herbier reconstitu\u00e9 \u00e0 partir de r\u00e9implantations. (La situation est diff\u00e9rente au Japon et aux USA o\u00f9 des r\u00e9implantations se sont faites \u00e0 une \u00e9chelle plus importante). Les co\u00fbts peuvent sembler \u00e9lev\u00e9s mais pourraient sans doute diminuer dans le cas d’op\u00e9rations de taille significative. Compar\u00e9s aux co\u00fbts d’autres op\u00e9rations de pr\u00e9servation de la qualit\u00e9 des milieux ou de restauration des \u00e9cosyst\u00e8mes littoraux, ils sont acceptables. En fait, le principal frein aux op\u00e9rations de r\u00e9implantations de phan\u00e9rogames marines n’est pas un obstacle m\u00e9thodologique ou financier. Trop souvent, les op\u00e9rations de r\u00e9implantation n’ont pas \u00e9t\u00e9 coupl\u00e9es \u00e0 une r\u00e9flexion globale sur la mitigation ou la r\u00e9habilitation. Un code de conduite pr\u00e9cis et un arbre d\u00e9cisionnel<\/a> ont \u00e9t\u00e9 r\u00e9dig\u00e9s \u00e0 la demande du Minist\u00e8re de l’Environnement par Boudouresque et al.<\/em>, 2021. La r\u00e9implantation des phan\u00e9rogames marines constitue un outil efficace, \u00e0 la condition qu’un processus d\u00e9cisionnel coh\u00e9rent<\/strong> soit mis en \u0153uvre, dans le cadre d’une gestion int\u00e9gr\u00e9e des milieux littoraux<\/strong> \u00e0 l’\u00e9chelle r\u00e9gionale.<\/p>\n\n\n\n
