Protected species recorded in the declared communes
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.
2,660 species recorded in the declared communes
259 protected animal species among them and 15 protected plants
24 animal species threatened on the national Red List, protected or not (vulnerable, endangered or critically endangered)
186 Birds
28 Mammals, bats included
17 Reptiles
11 Amphibians
9 Fish, molluscs and crayfish
8 Insects
For birds, the category is the one of their population at the flood's season (breeding, wintering or passage birds): a bird with no dated record in the declared communes in that season in the GBIF data has none, and the breeding category needs at least two dated records in June or July. In the migration season (March, August to October), a bird that neither the passage list nor the wintering list assesses takes its breeding category only if it was recorded at least twice in the declared communes in June or July. The list used is named under each species.
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 "in the communes or nearby".
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 in the communes declared for this flood, taken whole, 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.

National register of associations
Of the 460 livestock businesses in the SIRENE register: 216 cattle, sheep, goat or pig farms, 47 horse farms, 64 poultry farms and 133 farms of other animals.
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 declared communes can work in them.
Protected areas in the declared communes
The sites the communes declared for this flood extend over, taken whole, dry sectors included. Natura 2000 and regulatory protection first, then the ZNIEFF, each by its area in these communes. These are not flooded areas: they are not given.
