However,
Thousands birds victims botulism loire-atlantique:
In the Loire-Atlantique several birds are affected by an epidemic of avian botulism which strikes. Moreover, several areas of the region.
Recovered in a green marsh that has become fatal, hundreds of corpses of birds are piled up in trash cans. However, They were broke by the epizootic of avian botulism which affects several wetlands of Loire-Atlantique. For example, after a start of summer combining strong heat and waves of drought.
“In July, we should have birds that are stealing, singing. Moreover, There. However, it is silence, it is deadly,” describes Frédéric Richeux, president of the Union of Grande Brière Water Game.
“It’s a Crève-Coeur” – Thousands birds victims botulism loire-atlantique
In boots. Meanwhile, hugs, carefully gloved hands although the avian stump of botulism is not transmitted to man, some 150 hunters and volunteer fishermen crisscrossed the Brière marshes on Saturday. Similarly, In small groups, they disembark barges, counting the birds collected thousands birds victims botulism loire-atlantique before pouring the corpses in bins.
“Whatever the species we find, it is a Crève-Coeur. Moreover, This marsh which is our corner of paradise. we will have transformed it into real hell”, loose Frédéric Richeux.
In total, some 600 corpses, including a lot of collars, were picked up on this marshes on Saturday.
Thursday. more than 3,000 corpses of victims of avian botulism had already been gathered in Loire-Atlantique, notably in the Brière marsh and on Lake Grand-Lieu, southwest of Nantes, according to the prefecture of the department.
Threatened migratory birds
If some cases of avian botulism are not “unusual” in summer in Loire-Atlantique. such mortality had not been observed since 1995, specifies Eric Provost, president of the Brière regional park, which has some 25,000 hectares of wetlands.
In particular, in question a wave of heat and “sustainable” drought at the beginning of the summer, he explains. Considered as “the most important disease in thousands birds victims botulism loire-atlantique terms of mortality for water birds on a global scale”. avian botulism can cause the loss of tens of thousands of individuals during an episode, according to the ANSES (National Agency for Health Safety of Food, Environment and Work).
This disease is caused by a bacteria naturally present in these wetlands. which develops in hot weather in stagnant waters. It translates into volatiles by nervous involvement leading to progressive paralysis.
“An agony. ” laments Frédéric Richeux, who worries about seeing the disease touching migratory birds “will arrive in the coming weeks”. In an attempt to curb the propagation, the collections of the reached volatiles have multiplied since mid-July. They are even “almost daily” around Lake Grand-Lieu.
Because the asticots that develop on the carcasses of birds killed by botulism are carrying the bacteria. are likely to contaminate the birds that will eat them.
“An electric shock for this territory”
“We have been making thousands birds victims botulism loire-atlantique a big collection effort for three weeks. but with a fairly mixed success: we always collect as much. The usual episodes are circumscribed to an area. two around the lake, but this year the perimeter is very wide,” deplores Jean-Marc Gillier, director of the national reserve of Lac de Grand-Lieu.
Frédéric Richeux calls for “an electric shock for this territory” with “real hydraulic management” from next year. “Spring water should not go by millions of cubic meters at sea as it is currently done,” he insists.
The manager of hunters particularly points to agricultural uses which according to him a level of water too low in the marsh. for breeding and fodder. Eric Provost does not deny these “conflicts of uses”. but above all believes that it is a “water regulation” unsuitable for an exceptional year that is involved.
“In January, we have practically reached the highest levels of water known on the thousands birds victims botulism loire-atlantique marsh since we have made statements. And there. at the end of June, we got closer to the lowest water levels,” notes the president of the Brière regional park.
For him. “the water regulation, very clearly, is not designed for this type of year”, which may become more and more frequent with climate change.
