Le lac de Grand-Lieu, patrimoine naturel exceptionnel reconnu \u00e0 l\u2019\u00e9chelle nationale et internationale, est en danger. C\u2019est l\u2019alerte transmise par deux associations locales qui annoncent, ce lundi 8\u00a0juin, leur intention de d\u00e9poser, prochainement, un recours contentieux contre l\u2019\u00c9tat et le pr\u00e9fet de Loire-Atlantique concernant la gestion des niveaux d\u2019eau du lac.<\/p>\n
En juillet\u00a02025, plus de 3\u00a0000\u00a0cadavres d\u2019oiseaux, dont de nombreuses esp\u00e8ces prot\u00e9g\u00e9es, avaient \u00e9t\u00e9 ramass\u00e9s au lac de Grand-Lieu, au sud de Nantes\u00a0(Loire-Atlantique), en raison d\u2019une \u00e9pid\u00e9mie de botulisme<\/a>. Nos associations consid\u00e8rent que les prescriptions r\u00e9glementaires encadrant la gestion hydraulique n\u2019ont pas \u00e9t\u00e9 respect\u00e9es en 2025, alors m\u00eame que les conditions m\u00e9t\u00e9orologiques exceptionnelles et les effets du changement climatique imposaient une vigilance renforc\u00e9e, expliquent l\u2019Association d\u00e9partementale des chasseurs de gibier d\u2019eau de Loire-Atlantique\u00a0(ADCGELA) et l\u2019Association des sauvaginiers du lac de Grand-Lieu\u00a0(1).<\/p>\n Lire aussi\u00a0:<\/strong>\u00a0REPORTAGE.
