A late flood of the Loire, whose peak was reached on Sunday July 3, submerged 58 km of sandbanks between Montsoreau (Maine-et-Loire), east of Saumur, and Les Ponts-de-Cé , near Angers, a Natura 2000 classified area. Results: three species of protected birds, emblematic of the river – terns, small plovers and stone curlews – are threatened because they nest on the ground. Eleven of their thirteen breeding sites may have been drowned.

The suddenness of the phenomenon may have surprised them. “The decline is as fast as the flood. Their sequence creates a gutter effect whose violence is formidable,” insists Damien Rochier. “The gradual disappearance of wetlands, which absorb this water, makes the situation even more complicated,” says Damien Rochier. The “wave” may have destroyed half of the populations. A first assessment will be established in the middle of the week.
This late flood is explained by heavy rainfall in the Massif Central. A phenomenon known but formerly spaced out in time. “But, for three years, it has been repeated regularly, laments Damien Rochier. And we are helpless. »
