Protected species recorded within reach

Observations recorded in the ten years before the flood, some known only to within a few kilometres, up to 10 km, when their published position is blurred or given by grid square. They tell which species were reported there, not what became of each animal.

  • 93 species recorded within reach

  • 28 protected animal species among them

  • 28 Birds

In the water's path

Establishments registered today within reach of the flood, at their declared address or at the point Géorisques gives. They were not necessarily there on the day of the flood, and the dataset does not say whether they were flooded. An ICPE-classified farm can also be in the SIRENE register: these counts do not add up.

  • No ICPE-classified livestock farm located within the flood's reach

    Géorisques · ICPE

  • No livestock business in the SIRENE register based within the flood's reach

    SIRENE register · Insee

  • No veterinary practice based within the flood's reach

    SIRENE register · Insee

  • No animal protection association based within the flood's reach

    National register of associations

  • No wildlife association based within the flood's reach

    National register of associations

A wildlife association is an association whose declared purpose in the national register of associations is the preservation of wildlife: the register does not say whether it runs an authorised care centre. Associations are counted at their declared address: an association or a care centre based outside the area can work across all of it.

Protected areas within reach

Area of each site within reach of the flood, and the share of the site it represents. Natura 2000 and regulatory protection first, then the ZNIEFF.

A marsh can be designated twice under Natura 2000, for its habitats and for its birds: when both sites carry the same name, or have the same extent and almost the same area here, they share one row. Natura 2000 areas overlap and do not add up. A ZNIEFF is a wildlife inventory, with no regulatory protection.
