Dans le cadre de la d\u00e9marche Natura 2000 les Usses, le Syr\u2019Usses, Syndicat de Rivi\u00e8res Les Usses, proc\u00e8de depuis 2017 \u00e0 des travaux de restauration de deux friches \u00e0 molinie pr\u00e9sentes sur les communes de Seyssel et d\u2019Usinens. Ces travaux sont rendus possible gr\u00e2ce \u00e0 l\u2019accord des propri\u00e9taires des parcelles, et \u00e0 la signature de contrats Natura 2000, permettant un financement \u00e0 100% de ces actions par l\u2019Etat Fran\u00e7ais.<\/p>\n\n\n\n

Ces friches, d\u00e9sign\u00e9es comme habitats naturels d\u2019int\u00e9r\u00eat communautaire du site Natura 2000, accueillent une faune et une flore typiques. Cependant, en l\u2019absence d\u2019entretien, les sites ont tendance \u00e0 se refermer (progression des ligneux) et la molinie, grande gamin\u00e9e typique de ces milieux, emp\u00eache les autres esp\u00e8ces v\u00e9g\u00e9tales de s\u2019exprimer pleinement.<\/p>\n\n\n\n

Ainsi, des interventions ont a eu lieu les 6 et 7 novembre 2023 par les Brigades Vertes du Genevois, entreprise d\u2019insertion sp\u00e9cialis\u00e9e dans la gestion des espaces naturels. Ces interventions ont consist\u00e9 \u00e0 faucher la molinie, en exportant la mati\u00e8re fauch\u00e9e en bordure du site. Ces pratiques permettent le maintien d\u2019un milieu ouvert, tout en limitant la formation de mati\u00e8re organique par d\u00e9composition des v\u00e9g\u00e9taux. Ces conditions s\u2019av\u00e8rent optimales pour le d\u00e9veloppement d\u2019une flore typique et d\u2019une faune rare et prot\u00e9g\u00e9e comme le Damier de la Succise (papillon dont la plante h\u00f4te est la Succise des Pr\u00e9s).<\/p>\n\n\n\n

Chaque ann\u00e9e, les sites sont suivis pour contr\u00f4ler les effets des interventions. Bien que le Damier de la Succise ne soit pas encore pr\u00e9sent, de fortes densit\u00e9s de Succises sont pr\u00e9sentes ainsi que plusieurs esp\u00e8ces v\u00e9g\u00e9tales d\u2019int\u00e9r\u00eat patrimonial, dont l\u2019Aster amelle (pr\u00e9sente \u00e0 Seyssel), ou des orchid\u00e9es.<\/p>\n\n\n\n
