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.

  • 341 species recorded within reach

  • 104 protected animal species among them

  • 93 Birds

  • 4 Reptiles

  • 3 Amphibians

  • 2 Insects

  • 2 Mammals, bats included

The most notable protected animal species

Species with at least three observations (for a bird, three in the months that give it its category, and no bird without a record at the flood's season), the most threatened first, then the most recorded. An observation is a published record: it can count one or several animals, and the same animal can be noted several times. When their published position is imprecise, blurred or given by grid square, they are said to be "within reach or nearby".

Insects

Birds

The observations cover every season: a migrant bird recorded there may have been away on the day of the flood.

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.

The declared communes

173 communes declared a natural disaster (flood) for this flood, région by région, then département by département.
