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.
620 species recorded within reach
186 protected animal species among them and 6 protected plants
14 animal species threatened on the national Red List, protected or not (vulnerable, endangered or critically endangered)
177 Birds
4 Reptiles
3 Amphibians
2 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 within reach 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 within reach 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 "within reach 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 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.

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.
